write a program for an automatic teller machine that dispens

write a program for an automatic teller machine that dispenses money. the user should enter the amount of desired (a multiple of 10 dollars) and the machine dispenses this amount using the last number of billes. the bills dispensed are 50\'s, 20s, and 10s. write a function that determines how many of each kind of bill to dispense

Solution

#include <stdio.h>

float     amount;

int        fifties, twenties, tens, fives, ones;

float     cents;

int *fiftyDollarBills,*twentyDollarBills,*tenDollarBills,*fiveDollarBills,*oneDollarBills;

void displayTotals(float);

void myMain();

int main(int argc, const char *argv[])

{

cents                = 0;

// printf(\"PLease...\");

// scanf(\"%f\",&amount);

// printf(\"amount %f\",amount);

inputAmount();

}

void inputAmount()

{
