Welcome to the board/community! When posting code please use code tags as discussed in the watermark in the Message box, or in the announcement section at the top of the board. This will preserve the indentation you use (hopefully) when writing code. Without the indentation many of the more experienced people who frequent this site won't look at your code and you may miss valuable opportunities for assistance.

You compiler should be able to handle the use of namespaces and up to date header files. It is to your distinct advantage to use them. That would change your header files to iostream instead of iostream.h, etc. You will need to include material from namespace std either by writing an using statement of by using the scope operator.

Your program so far doesn't need a header file other than iostream.

Don't use void as the return type for main(). It's not standard. Your compiler will handle int as the return type without a problem.

Don't redeclare the following functions in main():
double monthly_income() ;
double loan() ;
double outstanding_credit_card_balance () ;
double loan_commitment () ;

If you want to call the functions leave the double off the front of each line above.

Minimize use of global variables. Make them local if at all possible.

Your functions return type double. Storing the return values in local variables for later use is best. Right now you are ignoring the return values because you are using global variables. If you really want to do that, then use type void for the function return values, though that is no the best solution.
