#define DIME 10

#define NICKEL 5

#define PENNY 1

void calculatedChange(int userAmount,int coinValues[])

{

if (userAmount >=100)

{

coinValues[0]=userAmount/DOLLAR;

userAmount=userAmount-(100*coinValues[0]);

}

if (userAmount >=25)

{

coinValues[1]=userAmount/QUARTER;

userAmount=userAmount-(25*coinValues[1] );  

}

if (userAmount >=10)

{

coinValues[2]=userAmount/DIME;

userAmount=userAmount-(10*coinValues[2]);

}

if (userAmount >=5)

{  

coinValues[3]=userAmount/NICKEL;

userAmount=userAmount-(5*coinValues[3]);

}

if (userAmount >=1)

{

coinValues[4]=userAmount/PENNY;

userAmount=userAmount-coinValues[4];

}

}

int main() {

int amount;

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

scanf("%d",&amount);

if(amount<1)

{

printf("No change..!");

}

else

{

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

calculatedChange(amount,coinValues);

if (coinValues[0]>0)

{

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

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

}

if (coinValues[1]>0)

{

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

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

}

if (coinValues[2]>0)

{

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

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

}

if (coinValues[3]>0)

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

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

}

if (coinValues[4]>0)

{

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

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

else printf("y");

}

}

}

  • Use conditional statements to check dollars , quarters , dimes , nickels  and penny.
  • Inside the main method , validate the input  and then  print dollars , dimes , nickels after checking them.
