Write a program with total change amount as an integer input, and output the change using the fewest coins, one coin type per line. the coin types are dollars, quarters, dimes, nickels, and pennies. use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies.

The C code is given below with appropriate comments

Explanation:

#include<stdio.h>

//defining constants

#define DOLLAR 100

#define QUARTER 25

#define DIME 10

#define NICKEL 5

#define PENNIES 1

//converting method

void ExactChange(int userTotal,int coinVals[])

{

//checking dollars

if (userTotal >=100)

{

coinVals[0]=userTotal/DOLLAR;

userTotal=userTotal-(100*coinVals[0]);

}

//checking quarters

if (userTotal >=25)

{

coinVals[1]=userTotal/QUARTER;

userTotal=userTotal-(25*coinVals[1] );

}

//checking dimes

if (userTotal >=10)

{

coinVals[2]=userTotal/DIME;

userTotal=userTotal-(10*coinVals[2]);

}

//checking nickels

if (userTotal >=5)

{

coinVals[3]=userTotal/NICKEL;

userTotal=userTotal-(5*coinVals[3]);

}

//checking pennies

if (userTotal >=1)

{

coinVals[4]=userTotal/PENNIES;

userTotal=userTotal-coinVals[4];

}

}

//main method

int main() {

//defining the variables

int amount;

//asking for input

printf("Enter the amount in cents :");

//reading the input

scanf("%d",&amount);

//validating the input

if(amount<1)

{

//printing the message

printf("No change..!");

}

//when the input is >0

else

{

int coinVals[5]={0,0,0,0,0};

ExactChange(amount,coinVals);

//checking dollars

if (coinVals[0]>0)

{

//printing dollars

printf("%d Dollar",coinVals[0]);

if(coinVals[0]>1) printf("s");

}

//checking quarters

if (coinVals[1]>0)

{

//printing quarters

printf(" %d Quarter",coinVals[1]);

if(coinVals[1]>1) printf("s");

}

//checking dimes

if (coinVals[2]>0)

{

//printing dimes

printf(" %d Dime",coinVals[2]);

if(coinVals[2]>1) printf("s");

}

//checking nickels

if (coinVals[3]>0)

{

//prinitng nickels

printf(" %d Nickel",coinVals[3]);

if(coinVals[3]>1) printf("s");

}

//checking pennies

if (coinVals[4]>0)

{

//printing pennies

printf(" %d Penn",coinVals[4]);

if(coinVals[4]>1) printf("ies");

else printf("y");

}

}

//end of main method

}

i don't understand really? can u provide more information

u should make a machine that can make ice cream fresh!
