Thread: why is math not calculating properly

In my code, I cannot figure why it still is calculating wrong:

here is the execute:

BANK RECONCILIATION FOR: 10/21/98

Ending balance on statement:350
Enter Outstanding dep (or 0 to quit)>75
Enter outstanding dep (0 to quit)>20
Enter outstanding dep (0 to quit)>150
Enter outstanding dep (0 to quit)>25
Enter outstanding dep (0 to quit)>0
Outstanding withdrawal (or 0 to quit)>57.85
Enter withdrawal (0 to quit)>200
Enter withdrawal (0 to quit)>50
Enter withdrawal (0 to quit)>125.38
Enter withdrawal (0 to quit)>0
Your final balance in your checkbook should be $ 169.62

Why is this happening it should be: 186.77

Code:

#include <stdio.h>

#define SENTINEL 0

float finbal, outdep, withdraw;

int main (void)


{

		  printf("BANK RECONCILIATION FOR: 10/21/98");


	      printf("\n\nEnding balance on statement:");
		  scanf ("%f", &finbal);



		  printf("Enter Outstanding dep (or %d to quit)>", SENTINEL);
		  scanf ("%f", &outdep);

while (outdep!= SENTINEL)
	{

		printf("Enter outstanding dep (%d to quit)>", SENTINEL);
		scanf("%f", &outdep);
		finbal = finbal + outdep;

	}

printf("Outstanding withdrawal (or %d to quit)>", SENTINEL);
scanf ("%f", &withdraw);

while (withdraw!=SENTINEL)
	{

		printf("Enter withdrawal (%d to quit)>", SENTINEL);
		scanf("%f", &withdraw);
	    finbal = finbal - withdraw;
	}
    /* the outstanding deposits and withdrawals, are already sub-totaled
    into finbal. So this is all you need:
    */


	printf("Your final balance in your checkbook should be $ %.2f\n" , finbal);

	return 0;

  }

Do you have any plans to add the first deposit and subtract the first withdrawal?

I do not understand.

The first deposit. You don't add it in, you go straight to asking for the second deposit.

The first withdrawal. You don't subtract it out, you go straight to asking for the second withdrawal.

I see what you mean but I do not know how to fix this

Order the three statements in your loop in the correct order (i.e., the first thing you must do is process the validated transaction, then print a prompt, then get input).

Adak,

I changed it back to my original, It does work. Thank you. I made other changes that were commented on im the thread and that threw me way off.
