# Answered Essay: practice using cout, cin, getline, setprecision() and basic Mathematical operations

practice using cout, cin, getline, setprecision() and basic Mathematical operations such as divide and modulus.
Your program should ask for a name and amount in dollars and cents.
It will then do the division and output the name, dollars, quarters, dimes, nickels, and pennies.
It must ask this 3 times.
An example output is below: Please enter your name and the amount: Gabriel 1.42 Hello Gabriel! You have 1 dollar, 1 quarter, 1 dime, 1 nickel, and 2 penny.

## Expert Answer

Here is the code for you:

#include <iostream>
using namespace std;
int main()
{
double amount;
string name;
//Reads input.
cout << “Please enter your name and the amount: “;
cin >> name >> amount;

//Count the possible number of dollars.
int dollarCount = 0;
while(amount >= 1)
{
dollarCount++;
amount -= 1;
}
//Count the possible number of quarters.
int quarterCount = 0;
while(amount >= 0.25)
{
quarterCount++;
amount -= 0.25;
}
//Count the possible number of dimes.
int dimeCount = 0;
while(amount >= .10)
{
dimeCount++;
amount -= 0.10;
}
//Count the possible number of nickels.
int nickelCount = 0;
while(amount >= 0.05)
{
nickelCount++;
amount -= 0.05;
}
//Count the possible number of pennies.
int pennyCount = 0;
while(amount > 0.01)
{
pennyCount++;
amount -= 0.01;
}

//Displays the data to screen.
cout << “Hello ” << name << “!” << endl;
cout << “You have ” << dollarCount << ” dollar, “;
cout << quarterCount << ” quarter, “;
cout << dimeCount << ” dime, “;
