==Mod down by integer==

<source lang="cpp">#include <iostream>
using namespace std;
int main()
{
cout << "How many pennies do you have? ";
int pennies;
cin >> pennies;

cout << "How many nickels do you have? ";
int nickels;
cin >> nickels;
cout << "How many dimes do you have? ";
int dimes;
cin >> dimes;
cout << "How many quarters do you have? ";
int quarters;
cin >> quarters;
int value = pennies + 5 * nickels + 10 * dimes
+ 25 * quarters;
int dollar = value / 100;
int cents = value % 100;
cout << "Total value = " << dollar << " dollar and "
<< cents << " cents\n";
return 0;
}</source>

==Modular operator==

<source lang="cpp">#include <iostream>
using namespace std;
int main(void)
{
int num;
cout << "Enter a whole number: ";
cin >> num;
if ( num % 2 == 0 )
cout << "The number is even" << endl;
return 0;
}</source>

==Read int type variables and calculate mod value==

<source lang="cpp">#include <iostream>
#include <string>
using namespace std;
int main(void)
{
int total, dollars, quarters, dimes, nickels, leftover;
cout << "Enter number of pennies to make change for: ";
cin >> total;
dollars = total / 100;
leftover = total % 100;
quarters = leftover / 25;
leftover %= 25;
dimes = leftover / 10;
leftover %= 10;
nickels = leftover / 5;
leftover %= 5;
cout << "Dollars: " << dollars << endl;
cout << "Quarters: " << quarters << endl;
cout << "Dimes: " << dimes << endl;
cout << "Nickels: " << nickels << endl;
cout << "Pennies: " << leftover << endl;
return 0;
}</source>

==The modulus operator.==

<source lang="cpp">#include <iostream>
using namespace std;

int main()
{
int x, y;

x = 10;
y = 3;
cout << x << " / " << y << " is " << x / y <<
" with a remainder of " << x y << "\n";

x = 1;
y = 2;
cout << x << " / " << y << " is " << x / y << "\n" <<
x << " y;

return 0;
}</source>
<pre class=codeResult>10 / 3 is 3 with a remainder of 1
1 / 2 is 0
1 % 2 is 1"</pre>
