READING AND WRITING FROM A FILE(WRITTEN IN ANOTHER LANGUAGE)

Question

# Comment
INTEGER Declares integer type variable
STRING Declares string type variable
LET Assigns a variable
CALCULATE Performs an arithmetic calculation
PRINT Writes data to the console
PRINTLN As print, but followed by a new line
END Terminates the program
Each line of the program must begin with one of these words, and the language should not be case sensitive.

COMMENT
Any line beginning with the # character is completely ignored.
Example:
# ignore this line!
INTEGER
The INTEGER reserved word declares an Integer variable, and assigns a default value of 0 to it.
Example:
INTEGER myInt
This example is equivalent to the Java statment "int myInt=0;"
STRING
The STRING reserved word declares a String variable, and assigns an empty string to it.
Example:
STRING myString
This is equivalent to the Java statement "String myString;"
LET
This assigns values to variables (either integers, or strings enclosed
in double quotes).
Examples:
LET myInt=42
LET myString="Hello World!"
CALCULATE
This performs numeric calculations upon values or variables, and assigns the result to a variable (which must have
been declared earlier). Four operators are supported: + *
and / (for addition, subtraction multiplication and
integer division respectively).
Examples:
CALCULATE myInt=2*2
CALCULATE myInt=myInt+24
CALCULATE myInt=intA/intB
PRINT and PRINTLN
These words both print to the console the
only difference being that PRINTLN appends a new line (as does
System.out.println in Java). These can print either text provided as an argument, or variables (string or integer).
Examples:
PRINTLN "Hello World!"
PRINT myString
PRINTLN myInt
END
This terminates the program, and prints a message to that effect.
TPL Example
To the left is an example TPL input file , to
calculate the factorial of 5. This should produce
an output similar to that shown overleaf (except
that calculates the factorial of 10).
# A TPL Program to calculate the factorial of 5
INTEGER myInt
INTEGER factorial
STRING myString
LET mystring="Factorial Program"
LET myInt=5
CALCULATE factorial=myInt*4
CALCULATE factorial=factorial*3
CALCULATE factorial=factorial*2

PRINTLN mystring
PRINTLN
PRINT "The factorial of "
PRINT myInt
PRINT " is "
PRINTLN factorial
END
Documentation
Document your code by writing instructions explaining how to run it, listing all of the files you have submitted,
and specifying any limitations (eg you might want to say what platforms you would expect it to run on, and what
platforms you have tested it on). This document should be written as a plain text file (ie ASCII � MS Word binary
files are not acceptable) � and this file should be called README.TXT. This file should constitute the user
manual of your program, and should explain exactly how to use your program.
The README file should be the user manual for your language as implemented.
NB:
I want it to read values from the file as given above and execute the answer in the command prompt( as intented in the file above)
Thanks

Hai I have one doubt in doing other peoples homework for them. Why bother?
