## Introduction

Arithmetic operators are used to perform calculations.

Operator | Significance |
---|

+ | Addition |

- | Subtraction |

* | Multiplication |

/ | Division |

% | Remainder |

## Demo

#include <iostream>
using namespace std;
int main() /*w ww.j a v a2 s. co m*/
{
double x, y;
cout << "\nEnter two floating-point values: ";
cin >> x >> y;
cout << "The average of the two numbers is: "
<< (x + y)/2.0 << endl;
return 0;
}

## Result

## Note

Divisions performed with integral operands will produce integral results; for example, 7/2 equals to 3.

If at least one of the operands is a floating-point number, the result will be a floating-point number; e.g., the division 7.0/2 produces 3.5.

Remainder division is only applicable to integral operands and returns the remainder of an integral division. For example, 7%2 returns 1.
