Explanation:
The following code is written in Java. It asks the user to enter the amount of change needed. This is done as a double since we are dealing with coins and not full dollar values alone. It then makes the necessary calculations to calculate the number of each coin needed and outputs it back to the user. A test case has been provided in the picture below with a sample output.
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
int dollars = 1;
double quarters = 0.25;
double dimes = 0.10;
double nickels = 0.05;
double pennies = 0.01;
Scanner in = new Scanner(System.in);
System.out.println("Enter Change Value: ");
double change = in.nextDouble();
int numDollars, numQuarters, numDimes, numNickels, numPennies;
double newChange;
numDollars = (int) (change / dollars);
newChange = change % dollars;
numQuarters = (int) (newChange / quarters);
newChange = newChange % quarters;
numDimes = (int) (newChange / dimes);
newChange = newChange % dimes;
numNickels = (int) (newChange / nickels);
newChange = newChange % nickels + 0.001;
numPennies = (int) (newChange / pennies);
newChange = newChange % pennies;
System.out.println("Minimum Num of Coins needed: ");
if (numDollars != 1) {
System.out.println(numDollars + " Dollars");
} else {
System.out.println(numDollars + " Dollar");
}
if (numQuarters != 1) {
System.out.println(numQuarters + " Quarters");
} else {
System.out.println(numQuarters + " Quarter");
}
if (numDimes != 1) {
System.out.println(numDimes + " Dimes");
} else {
System.out.println(numDimes + " Dime");
}
if (numNickels != 1) {
System.out.println(numNickels + " Nickels");
} else {
System.out.println(numNickels + " Nickel");
}
if (numPennies != 1) {
System.out.println(numPennies + " Pennies");
} else {
System.out.println(numPennies + " Penny");
}
}
}
The program is an illustration of conditional statements
Conditional statements are used to make decisions
The program in C++ where comments are used to explain each line is as follows
#include<iostream>
using namespace std;
int main() {
// This line declare all the variables
int amount, dollar, quarter, dime, nickel, penny;
// This prompts the user for input (i.e. the amount)
cout<<"Amount: ";
//This gets the amount from the user
cin>>amount;
// This checks if the amount is 0 or less
if(amount<=0) {
//This prints "No Change"
cout<<"No Change";
}
//If the amount is greater than 0
else {
// These convert the amount to various coins
dollar = amount/100;
amount = amount%100;
quarter = amount/25;
amount = amount%25;
dime = amount/10;
amount = amount%10;
nickel = amount/5;
penny = amount%5;
// The next lines print the coins
if(dollar>=1) {
if(dollar == 1) {
cout<<dollar<<" dollar\n"; }
else {
cout<<dollar<<" dollars\n"; }
}
if(quarter>=1) {
if(quarter== 1) {
cout<<quarter<<" quarter\n";
}
else {
cout<<quarter<<" quarters\n";
}
}
if(dime>=1) {
if(dime == 1) {
cout<<dime<<" dime\n";
}
else {
cout<<dime<<" dimes\n";
}
}
if(nickel>=1) {
if(nickel == 1) {
cout<<nickel<<" nickel\n";
}
else {
cout<<nickel<<" nickels\n";
}
}
if(penny>=1) {
if(penny == 1) {
cout<<penny<<" penny\n";
}
else {
cout<<penny<<" pennies\n";
}
}
}
return 0;
}
