# Arithmetic Operators in C

Advertisements

The following table shows all the arithmetic operators supported by the C language. Assume variable **A** holds 10 and variable **B** holds 20, then −

Operator | Description | Example |
---|---|---|

+ | Adds two operands. | A + B = 30 |

− | Subtracts second operand from the first. | A − B = -10 |

* | Multiplies both operands. | A * B = 200 |

/ | Divides numerator by de-numerator. | B / A = 2 |

% | Modulus Operator and remainder of after an integer division. | B % A = 0 |

++ | Increment operator increases the integer value by one. | A++ = 11 |

-- | Decrement operator decreases the integer value by one. | A-- = 9 |

## Example

Try the following example to understand all the arithmetic operators available in C −

Live Demo#include <stdio.h> main() { int a = 21; int b = 10; int c ; c = a + b; printf("Line 1 - Value of c is %d\n", c ); c = a - b; printf("Line 2 - Value of c is %d\n", c ); c = a * b; printf("Line 3 - Value of c is %d\n", c ); c = a / b; printf("Line 4 - Value of c is %d\n", c ); c = a % b; printf("Line 5 - Value of c is %d\n", c ); c = a++; printf("Line 6 - Value of c is %d\n", c ); c = a--; printf("Line 7 - Value of c is %d\n", c ); }

When you compile and execute the above program, it produces the following result −

Line 1 - Value of c is 31 Line 2 - Value of c is 11 Line 3 - Value of c is 210 Line 4 - Value of c is 2 Line 5 - Value of c is 1 Line 6 - Value of c is 21 Line 7 - Value of c is 22
