Question
I need to modify my code, but am having trouble with having it compile correctly. Here are the requirements I must follow. Any help would be so appreciated!There should be at least three non-trivial functions in the program! (by that I mean a function that does more than just print a line of text). For example, one function may be to find out how many deposits will be entered, , or the opening balance, or the message before the bank record. etc.
Outputting the contents of the arrays in "record form" is pretty straightforward, and should be done in a loop. (This could be a good place for a function.)
For example: I can use void as the function type and use an argument(s) (e.g. you can have void print_deposits_out ( float deposits [ ], int number_of_deposits) as a prototype.) And you could use a similar one for the withdrawals. Or, I could put the comment before the bank record into a function by sending the closing balance into the function.
#include <stdio.h>
