**ARITHMETIC OPERATORS**

The symbols of the arithmetic operators are:-

Operation |
Operator |
Comment |
Value of Sum before |
Value of sum after |

Multiply | * | sum = sum * 2; | 4 | 8 |

Divide | / | sum = sum / 2; | 4 | 2 |

Addition | + | sum = sum + 2; | 4 | 6 |

Subtraction | - | sum = sum -2; | 4 | 2 |

Increment | ++ | ++sum; | 4 | 5 |

Decrement | -- | --sum; | 4 | 3 |

Modulus | % | sum = sum % 3; | 4 | 1 |

The following code fragment adds the
variables *loop* and *count* together, leaving the
result in the variable *sum*

sum = loop + count;

Note: If the modulus **%** sign is needed to be displayed
as part of a text string, use two, ie %%

#include <stdio.h> main() { int sum = 50; float modulus; modulus = sum % 10; printf("The %% of %d by 10 is %f\n", sum, modulus); }Sample Program OutputThe % of 50 by 10 is 0.000000

**CLASS EXERCISE C5**

What does the following change do to the printed output of the
previous program?

printf("The %% of %d by 10 is %.2f\n", sum, modulus);
