I'm not using whole numbers in my program though. I'm using real numbers.
I also initialized my totals for each category to 0.00 so that it has a value to start off with before accumulations. However, this doesn't solve the problem as my program is still giving me crap values.
Here's the code to make it more easier:
/* Prob 10-3

*/
#include <stdio.h>
#include <stdlib.h>
double Get_Opening_Balance(); /* Gets the user's opening account balance */
void Choice_Menu(); /* Displays a menu for choices */
void Validate_Choice(double); /* Validates the user's choice from the menu */
double Deposit(double, double); /* Gets the user's deposit amount */
double Withdrawal(double, double); /* Gets the user's withdrawal amount */
double Check(double, double); /* Gets the user's check amount */
void Display_Results(double, double, double, double, double); /* Displays all results and totals */
main()
{
double open_balance_amount; /* The user's opening account balance */
/* Call functions */
open_balance_amount = Get_Opening_Balance();
Choice_Menu();
Validate_Choice(open_balance_amount);
}
double Get_Opening_Balance()
{
double open_acct_balance; /* The user's opening account balance */
/* Prompt the user */
printf("\nEnter the opening account balance: $");
scanf("%lf", &open_acct_balance);
if (open_acct_balance < 0.00)
exit(0);
else
return open_acct_balance;
