print (i * j)
I am not interested in an answer; I am able to type in to Java and see what the answer is. I want some ideas in relation to the approach in solving this problem in an examination.

Java code to pseudocode

Hi, i have written this program but I also need to submit the pseudo code for it and i'm not really sure how to do this.
Here is a sample of the code I have written, if someone could please get me on the write track so i can write the pseudocode for the whole thing that would be great.
Java code;
import TerminalIO.*;
public class MyFutureTIO
KeyboardReader reader = new KeyboardReader();
ScreenWriter writer = new ScreenWriter();
public void run()
// global instance variables
char keepdepositing='N';
double deposit, rate, balance=0 , withdrawals=0, interest=0, withdrawalyears=0, finalbalance=0, counter=0;
int age, years=0, continuedyears=0;
// Initial inputs to be able to determine when the loan matures
writer.print("Amount deposited per month: ");
deposit = reader.readDouble();
writer.print("Your age: ");
age = reader.readInt();
writer.print("Interest rate: ");
rate = reader.readDouble();
deposit = deposit*12;     // This is the yearly deposit amount
rate = rate/100;          // To convert the rate to a decimal
if (age >=60){      // This if statement is used when the age is over 60 years
years = 0;
for (int i = 0; i < years; i++)
balance = (balance + deposit) * (1 + rate);
if (counter % 10==0)
rate = rate + 0.01;
counter++;
writer.print("As you are 60 or older, your account is at maturity\n");
writer.print("Your account has a $" + balance +", but you can choose to deposit money from this point onwards\n");
writer.print("Would you like to start depositing?\n");
keepdepositing = reader.readChar();
if (keepdepositing == 'N'){ //the user doesn't want to open an account
writer.print("As you don't want to start depositing and your account has a $0 balance no account has been opened\n");
else if (keepdepositing == 'Y'){   //the user wants to start depositing into the account
writer.print("How many years would you like to deposit for? ");
continuedyears = reader.readInt();
for (int i = 0; i < continuedyears; i++)
balance = (balance + deposit) * (1 + rate);
writer.print("Your balance at this time will be: $" + balance);
interest = (balance*rate)/12;
writer.print("Your account will earn $" + interest + " per month in interest after this point\n");
writer.print("How much would you like to withdraw per month? ");
withdrawals = reader.readDouble();
writer.print("How many years would you like to withdraw for? ");
withdrawalyears = reader.readDouble();
for (int i = 0; i < withdrawalyears; i++) // do i need the counter here?
finalbalance = (balance - withdrawals*12)*(1 + rate);
writer.print("After this time your account will have a balance of: $" + finalbalance + "\n");
}

Yeah i did write this program, and i have actaully started to write the pseudocode but it doesn't seem write, i'm not sure if i'm putting to much in or not enough.
All of my notes say not to use any java key words in pseudocode, and this is confusing me a bit.
This is what I started to write for the psuedocode;
Get deposit
Get age
Get rate
If (age >= 60
years = 0
for (int 1=0;
Balance = (balance + deposit)*(1+rate)
Print As you are 60 or older, your account has reached maturity
Print Your account has a $0 balance, but you can choose to deposit money from this point onwards
Print Would you like to start depositing?
if (keepdepositing == �N�)
Print As you don�t want to start depositing and your account has a $0 balance no account has been opened�
else if (keepdepositing == �Y�)
     Print How many years would you like to deposit for?
     Balance = (balance + deposit) * (1 + rate)
     Print Your balance at this time will be $balance
     interest = (balance*rate)/12
     Print Your account will earn $interest per month after this point
     Print How much would you like to withdraw per month?
     Print How many years would you like to withdraw for?
     final balance = (balance � withdrawals*12)*(1 + rate)
     Print After this time your account will have a balance of $finalbalance

What is the standards to write pseudocode

Hi all,
If any one knows about standards of Pseudocode
plz pass it to me.
I need to write some pseudocode with proper standards.
Thanks.

There isn't really a "standard" for pseudocode per se. Pseudocode is just a term that describes something that's between natural language and programming source code. It tends to be somewhat like one or more actual programming languages, but without worrying about precise details of syntax, semicolons, etc., and there will be natural language thrown in for things that are tedious to write in a more computer-ish style.
For example:
fetch all students and their courses from database where student's registration status is complete
for each combination of student and class
if student has not completed prerequisites for class, email notice to student that he must get instructor's written permission.

Confusing with these pseudocode

I never write the psedocode for instantiable classes, so I am pretty confused at this time. For example, the following codes, how to convert them to pseudocode?
public class Invoice
     private String numb;
     private String descr;
     private int qu;
     private double pr;
     public Invoice()
          numb="";
          descr="";
          qu=0;
          pr=0;
    public void setPartNumber(String numb)
      this.numb=numb;
    public String getPartNumber()
        return numb;
    public void setDescription(String descr)
      this.descr=descr;
    public String getDescription()
        return descr;
    public void setQuantity(int qu)
        this.qu=qu;
    public int getQuantity()
        return qu;
    public void setPrice(double pr)
        this.pr=pr;
    public double getPrice()
        return pr;
    public double getInvoiceAmount()
        return qu*pr;
}Thanks

Check out the wikipedia definition of pseudocode:
Pseudocode (derived from pseudo and code) is a
compact and informal high-level description of a
computer programming algorithm that uses the
structural conventions of programming languages, but
omits detailed subroutines, variable declarations or
language-specific syntax.
I put in bold the key phrase to me. It is useful in
simplifying the description of programming
algorithms. Your code above algorithm-deficient.
It's not bad code, and it's not wrong code. It is
just not a good example of what pseudocode is useful
for.I have gone through with this and now understand when I have to use pseudocode.
thx:)

Help with pseudocode

hi. can someone helpe me translate this pseudocode please:
for each vertex v
        set kv to false
        set pv to unknown (or none, if v is the start vertex)
        set dv to infinity (or 0, if v is the start vertex)
    PriorityQueue pq = new PriorityQueue()
    pq.enqueue(start vertex, 0)
    while (!pq.isEmpty())
        vertex v = pq.dequeueMin();
        if (kv is false)
            kv = true
            for each vertex w such that edge v -> w exists
                if (dw > dv + C(v, w))
                    dw = dv + C(v, w)
                    pw = v
                    pq.enqueue(w, dw)
    }

Care to tell me what's wrong with this.
I was showing him what a for loop looks like and what
a for each looks like.Norweed,
Your code snippet is liable to cause far more confusion than clarity, for the following reasons:
The OP's pseudocode references "v" as an individual vector; your suggested code uses "v" as the collection of vectors.
The OP makes no mention of his collection of vectors being stored in an ArrayList; your code could be interpretted as "one must use an ArrayList in order to do a for loop".
Your ArrayList is not initialized, yet you make no "do initialization stuff" indication between its declaration and usage.
ArrayList does not have a component "size".
The usage of an index, "i", is extraneous as the pseudocode has no requirements for tracking a numeric index as the code loops through the collection of vectors. I find your later comment "I was showing him what a ... for each looks like." puzzling. Indeed, a for each style loop would have been appropriate, but it is missing from your post.
In short, to someone who has expressed confusion over how to wrie a for-loop, I cannot fathom how the following four lines of text would do anything but confuse that person even further:
ArrayList v;
for(int i=0; i<v.size; i++){
do stuff;

Translating pseudocode??

"left" is an int parameter in my method...
"k" is an int representing the middle index of an array called "a"...
Here is the pseudocode....
if searchValue < a[k]
return the result of searching the array from left to k - 1
if searchValue > a[k]
return the result of searching the array from k + 1 to right
Thanks for any help!!!!

Ok here we go
if searchValue < a[k]
return the result of searching the array from left to k - 1
if searchValue > a[k]
return the result of searching the array from k + 1 to rightpublic int[] searchFunction(int left) {
//Assuming searchvalue a global parameter...
//Assuming array also global..
int k = a.length/2;
int left = 3 //HardCoded.
int right = 7; // this i have assumed a variable cos left has also been assumed as an variable
int start = 0;
int stop = 0;
int len=0;
if (searchValue < a[k]) {
if (left < k) {
len = k - left;
start = left;
stop = k;
} else if (searchValue > a[k]) {
len = right - k;
start = k+1;
stop = right;
String str = new String[len]; //Assuming a as an String array.
for (int i=start; i<stop; i++) {
str[i] = a;
return str;
I don't know that this will work or not.. It might have some errors also but atleast try it out.. i have not compiled it .. may i'll be able to solve the problem.

Oracle : Flow for the Concep and Pseudocode

Hi,
Consider there are 4 jobs A,B,C and MAIN.The MAIN Job will call other subroutines based on the some condition.The Main Job will call the Job A on the first business day of the every week.also it will call JOB B on every business day.Also it will call the Job C on the first day of the every month. Can anyone suggest me the flow to do it?
I am using oracle 10g

Hi,
You do not need the MAIN job. You just need to create 4 scheduler jobs which each have a different schedule. See the Scheduler chapter of the Administrator's guide or the dbms_scheduler package documentation for help in setting up the exact schedules you need.
If you really want a main job, create a single main job which runs daily and then spawns the other tasks based on what day it is. You can have the other tasks be single one-time jobs if you want extra parallelism or just have the code inline in the main job
Hope this helps,
Ravi.

I don't even know why they offer Java courses at colleges. Students see it and think it will be like other classes (something that they have a chance in hell of understanding let alone passing).
I think Java 101 is the "flunk course" for computer science majors.
Like calculus is for business majors.
That way they know everyone will not pass and it will lend credability (in theory) to the degree.

Javascript - is there something like an "active row count" property??

Lets say I have a tabular form. Every time I use the form, the # of rows returned by the query will vary. Maybe first time I go to the page, the select statement returns only 5 rows, but the next day it returns 25 rows.
Is there some type of system variable to stores the # of rows visible on the page at a given time within this tabular form?
I realize that if I have an tabular form item with an id of f03 for example, then on each row it will be referenced as f03_0001, then f03_0002 on the next row and then f03_0003 on the next row etc...
In pseudocode, here is what I want to do:
For i = 1 to ACTIVE_ROW_COUNT (assuming this is the # of rows in the HTML table)
perform some operation on 'f03_000' + ACTIVE_ROW_COUNT
Do you see what I'm after? I checked the APEX api, but I couldn't find such a property. It seems like you can't do much if you can't figure out this current index # or the max on the page.
Also, I tried playing around with the "this" keyword in hopes of finding a pointer to the "current item" that would have triggered the onchange event, but no luck either.
Thanks in advance.

Hi:
Within javascript you can reference the columns of the tabular form as
<script>
col1 = document.forms0.f01; // the first updateable column of your report
alert (col1.length) ; // number of rows
</script>varad

How do i transfer funds from one account to another in the same table?

Say for example i want to transfer funds from UserID 1111101 to UserID 1111103.
Anyone know the procedure for this. I use php/mysql and dreamweaver.

Here's a very basic method. Note that this is just pseudocode - you'll need to work out the actual code (I assume you've learned how in your course studies). Keep in mind this is a very simplified workflow - a real bank transaction would be MUCH more complex.
Create a form that has fields for debit account, credit account, amount
In your script, assign the values from the form to local variables
$debit_acct
$credit_acct
$amount
I'll assume you have an account balance table 'acct_bal'. Have a journal table to store those values along with the date and autonumber transaction id.
Begin Trans
INSERT into journal (credit_acct, debit_acct, amount, trans_date) VALUES ($credit_acct, $debit_acct, $amount, NOW())
Get the transaction_id ($trans_id) from the INSERT statement- the method depends on which MySQL interface you are using.
UPDATE acct_bal SET balance = (balance + $amount) WHERE acct_id = $debit_acct
UPDATE acct_bal SET balance = (balance - $amount) WHERE acct_id = $credit_acct
Rollback on any SQL error else Commit Trans.
