Thread: Need help with C program

Yes, it should. From my "int main() {" line and on. Let me know if it doesn't.

Edit: If it doesn't, maybe this will:

Code:

#include <stdio.h>

int main() {
	// The file
	FILE *transactions;
	// The numbers
	float cost, payment, change;
	// The remainder in depth
	int penniesInTill = 0, nickelsInTill = 0, dimesInTill = 0, quartersInTill = 0;
	int dollarsInTill = 0, fivesInTill = 0, tensInTill = 0, twentiesInTill = 0;
	
	transactions = fopen ("transactions.dat", "r");
	if (transactions == NULL) {
		printf ("File, transactions, could not be opened\n");
	}

	fscanf(transactions, "%f\n", &cost);
	printf("The cost is %g\n", cost);
	fscanf(transactions, "%f\n", &payment);
	printf("The customer's payment was %g\n", payment);
	change = cost - payment;
	printf("The change due is %g\n", change);

	while (change >= 20.0f) {
		change -= 20.0f;
		twentiesInTill++;
	}
	while (change >= 10.0f) {
		change -= 10.0f;
		tensInTill++;
	}
	while (change >= 5.0f) {
		change -= 5.0f;
		fivesInTill++;
	}
	while (change >= 1.0f) {
		change -= 1.0f;
		dollarsInTill++;
	}
	while (change >= 0.25f) {
		change -= 0.25f;
		quartersInTill++;
	}
	while (change >= 0.10f) {
		change -= 0.10f;
		dimesInTill++;
	}
	while (change >= 0.05f) {
		change -= 0.05f;
		nickelsInTill++;
	}
	while (change >= 0.01f) {
		change -= 0.01f;
		penniesInTill++;
	}

	printf("In Detail\n\nTwenties: %d\nTens: %d\nFives: %d\nOnes: %d\nQuarters: %d\nDimes: %d\nNickels: %d\nPennies: %d\n",
	twentiesInTill, tensInTill, fivesInTill, dollarsInTill, quartersInTill, dimesInTill, nickelsInTill, penniesInTill);

	return 0;
}
