## Relational Operators in C

Relational operators in C are used to check the relation between two operands. **0** and **1** are the results given by relational operators. If the relationship comes out to be **true**, it returns **1**. If the relationship is **false**, it returns **0**.

The list of relational operators is given below:

Operator | Description |

== | Equal to: To check whether two operands are equal or not. |

!= | Not equal to |

> | Greater than |

< | Less than |

>= | Greater than or equal to |

<= | Less than or equal to |

## Example

Let’s understand all operators through a program.

#include<stdio.h> int main() { int a=8; int b=3; printf("%d",a==b); printf("\n%d",a!=b); printf("\n%d",a>b); printf("\n%d",a<b); printf("\n%d",a>=b); printf("\n%d",a<=b); }

## Output

## Explanation

Equality operator returns 0 since 8==3 is false.

Not equal to operator returns 1 since 8!=3 is true.

Greater than operator returns 1 since 8>3 is true.

Less than operator returns 0 since 8<3 is false.

Greater than or equal to operator returns 1 since 8>=3 is true.

Less than or equal to operator returns 0 since 8<=3 is false.

*Note: If either of the relations in ‘>=’ and ‘<=’ is true, the result will be 1. In ‘8>=3’, 8 is greater than 3, but 8 equals 3 is false. However, the overall output is true. In ‘8<=3’, both relations are false. Hence, the output is 0.*

## Difference Between ‘=’ and ‘==’

Most of the users always have confusion in ‘=’ and ‘==’ operators. However, both look the same but work differently in our programming languages.

‘**=**’ is the **assignment operator** that assigns a value to a variable.

‘**==**’ is the **equality operator** that compares the equality of two operands.

For example,

**Y=5;**

The above statement means we are assigning ‘5’ in the variable ‘Y’. Always remember that assignment is done from right to left.

Y==5;** **

Here, we compare whether ‘5’ is equal to ‘Y’ or not.
