Question

Write a program that helps a young student learn to make change. Use the random number generator to generate change amounts between1¢ and 99¢. Ask the user how many quarters, dimes, nickels and pennies they need to make that amount. Determine whether the coins specified by the user total the specified amount and give them feedback on their answer including whether they used the minimum or optimum number of coins to produce the amount.

Answer 1

Answer:

#include <iostream>

#include <stdlib.h>

using namespace std;

int main()

{

srand(time(0));

 

int coins = rand()%99 + 1;

int temp = coins;

cout<<"Enter the coins needed to make $0."<<coins<<"?"<<endl<<endl;

int a, b, c, d;

cout<<"Quarters? ";

cin>>a;

cout<<"Dimes? ";

cin>>b;

cout<<"Nickles? ";

cin>>c;

cout<<"Pennies? ";

cin>>d;

 

int quarters = coins/25;

 

coins = coins%25;

 

int dimes = coins/10;

 

coins = coins%10;

 

int nickles = coins/5;

coins = coins%5;

 

int pennies = coins/1;

 

if(((a*25) + (b*10) + (c*5) + (d*1))==temp)

{

cout<<"That's correct"<<endl;

 

if(a!=quarters || b!=dimes || c!=nickles || d!=pennies)

{

cout<<"The optimized solution is "<<endl;

}

}

else

{

cout<<"Not correct"<<endl;

cout<<"The solution is "<<endl;

 

}

 

cout<<"\tQuarters: "<<quarters<<endl;

cout<<"\tDimes: "<<dimes<<endl;

cout<<"\tNickles: "<<nickles<<endl;

cout<<"\tPennies: "<<pennies<<endl;

return 0;

}

Explanation:

• Use the built-in rand function to generate a random coin.
• Get all the required values for quarters, dimes, nickles and pennies and store them in variables.
• Check if the coins give a value of temp, then answer is correct and the values of user will be added.
• Optimum solution is displayed  If it does not matches with the optimum solution. Display that the answer is wrong along with solution.
