Question

You work at a bank and needs to automate the bills that are given to a customer when they cash a check. When the check is cashed, the system should automatically break down the dollar amount into the smallest number of $20, $10, $5, and $1 bills. Specifications: Write a program that prompts the user to enter a U.S dollar amount and then shows how to pay the customer using the smallest number of bills. After the program runs, prompt the user if he/she needs to enter another dollar amount, and repeat as necessary. After prompting the user to enter the dollar amount, scan it in and calculate the number of twenties, tens, fives, and ones that are necessary to pay to the customer. You may assume that the dollar amount is always an integer value. Since the program should allow the user to input multiple dollar amounts, use a do-while loop to help solve the problem. As an example, if you execute the program with the following underlined inputs, the output will be: -> main.o Enter a dollar amount : 93 $20 bills: 4 $10 bills: 1 $ 5 bills: 0 $ 1 bills: 3 Convert another dollar amount? (Y/N): Y Enter a dollar amount : 42 $20 bills: 2 $10 bills: 0 $ 5 bills: 0 $ 1 bills: 2 Convert another dollar amount? (Y/N): N >

Screenshot:

main.c WNE Ovau #include <stdio.h> int main() char choice; int amt, countTwenty=0,countTen=0,countFive-0,countone=0; printf("Enter a dollar amount: "); scanf("%d",&amt); if(amt>=20) countTwenty=amt/20; amt=amt-countTwenty*20; if(amt>=10) countTen=amt/10; amt=amt- countTen*10; 23 if(amt>=5) countFive=amt/5; amt=amt - countFive 5; if(amt>=0) countOne amt; amt=0; print("\n$20 bills: %d",count Twenty: printf("\n$10 bills: %d",countTen); printf("\n$5 bills: %d",countFive); printf("\n$1 bills: %d", countOne); printf("\nConvert another dollar amount? (Y/N): "); //Note the space before %C scanf("%c",&choice); }while(choice=='Y'); return 0;

Output:

Enter a dollar amount: 93 $20 bills: 4 $10 bills: 1 $5 bills: 0 $1 bills: 3 Convert another dollar amount? (Y/N): Y Enter a dollar amount: 42 $20 bills: 2 $10 bills: 0 $5 bills: 0 $1 bills: 2 Convert another dollar amount? (Y/N): N ...Program finished with exit code o Press ENTER to exit console.

Code:

#include <stdio.h>

int main()
{
char choice;
  
do
{
int amt,countTwenty=0,countTen=0,countFive=0,countOne=0;
printf("Enter a dollar amount: ");
scanf("%d",&amt);
if(amt>=20)
{
countTwenty=amt/20;
amt=amt-countTwenty*20;
}
if(amt>=10)
{
countTen=amt/10;
amt=amt- countTen*10;
}
if(amt>=5)
{
countFive=amt/5;
amt=amt- countFive*5;
}
if(amt>=0)
{
countOne=amt;
amt=0;
}
  
printf("\n$20 bills: %d",countTwenty);
printf("\n$10 bills: %d",countTen);
printf("\n$5 bills: %d",countFive);
printf("\n$1 bills: %d",countOne);
  
  
printf("\nConvert another dollar amount? (Y/N): ");
//Note the space before %c
scanf(" %c",&choice);
  
  
}while(choice=='Y');

return 0;
}
