Functional and structural testing

Question

Hello,
I would appreciate some information about functional and structural (white box and black box testing).
Could someone please give a brief example of each or any other information or tell me if the following 2 paragraphs make sense:
Structural testing is testing individual bits of code e.g. testing if a array holds the right information. Not sure how I would go about doing this tho, example would help.
Functional testing is more simple as this involves valid or invalid input into the program e.g. if a program compares 2 ages input by the user then functional tests would involve entering non valid ages (ages out of range and the wrong format) or correct ages.
Thanks anyone

Hello,
I would appreciate some information about functional
and structural (white box and black box testing).
Could someone please give a brief example of each or
any other information or tell me if the following 2
paragraphs make sense:
Structural testing is testing individual bits of code
e.g. testing if a array holds the right information.
Not sure how I would go about doing this tho, example
would help.System.out.println(aVariable);
Or:
if (obj.getSomeValue != x) System.out.println("Houston, we have a problem.")
Functional testing is more simple as this involves
valid or invalid input into the program e.g. if a
program compares 2 ages input by the user then
functional tests would involve entering non valid
ages (ages out of range and the wrong format) or
correct ages.It's just about calling a method to see whether it provides the correct results on good input and a defined error state on bad input.
