I need someone to look it over.. I have no clue how to post the coding up on this thing .. so please help!!!

Copy and paste the code, then highlight it and click the symbols that look like this: <> on the right.

Then post it.

yup

But you need to make sure your computer is on.
By the way did you know all your source code files can be opened with Notepad?

oh thanks! ..

i updated it now..

I really have no clue how to fix it to work.

Can you post the nature of this assignment? I'm having a hard time deciphering what the code is supposed to do.

I'll write out the question...

"You are to write a program that will do two things for the user: it will help them to evaluate how long it will take to achieve a certain investment goal given an annual investment amount and an annual rate of return; also, it will help them to evaluate how long it will take to pay off a loan given a principal amount, an annual payment amount and an annual interest rate. When the user runs the program, the program should ask which one of these procedures the user wants to perform, and then do that procedure. If the user wants to do another set of calculations (for example: for a loan instead of an investment, or for a loan followed by another loan), they will have the option of doing another set of calculations."
bool maybe (93)
For repeating a calculation multiple times you could try something like this:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
 
do
{
   // ....perform some sort of calculation....
   // ....
   // ....


   char repeat;
   cout << "would you like to repeat? (y/n)";
   cin >> repeat;
   while((repeat != 'y') && (repeat != 'Y') && (repeat != 'n') && (repeat != 'N'))
   {
        cout << "Invalid input. would you like to repeat? (y/n)";
        cin >> repeat;
   }
}while((ans == 'y') || (ans == 'Y'))
;

The do-while loop will execute the body at least once and then it may execute it several more times depending on if the argument inside "while" is true. I think you should think about starting the code over again and this time test the code whenever you get a little bit done. So first I would write a code making sure the program allows you to perform the calculation multiple times, then I would add the code that lets you calculate the investment and make sure THAT works and finally I would include the code that does the calculation for the loan. This may sound time consuming but I think it'll save you more time in the end.

I handed in as what I have it, I didn't understand anything~
Thanks for trying to help though!

you should learn the basics of c++ first, i see you have syntax errors...

like this:
 
 
loop = int loop()


you should write it like this:

1
2
3
4
5
6
7
8
9
10
11
12
 
//declare it first
//and don't forget the semicolon
int loop();

//as far as i know, you can't use the same name with function
int loop_one;

//don't forget to define you loop() function
loop_one = loop();

//you can declare it like this too:
//int loop_one = loop();
