## Relational Operators

Relational Operators are used to determine relationship between two operands. The output of the operation performed by relation operators on the operand is either 0 or 1. The different types of relational operators are as follow:

## i. is equal to

`==`

operator :Checks whether the operands on either sides are equal or not and returns 1 if equal else returns 0. For Example:

`Consider A = 20 and B = 10 A==B would results 0`

## ii. is not equal to

`!=`

operator :Checks whether the operands on either sides are equal or not and returns 1 if not equal else returns 0. For Example:

`Consider A = 20 and B = 10 A!=B would results 0`

## iii. is greater than

`>`

operator :Checks whether the operand on left side is greater than operand on right side and returns 1 if true. For Example:

`Consider A = 20 and B = 10 A>B would results 1`

## iii. is less than

`<`

operator :Checks whether the operand on left side is less than operand on right side and returns 1 if true. For Example:

`Consider A = 20 and B = 10 A<B would results 0`

## iii. is less than or equal to

`<=`

operator :Checks whether the operand on left side is less or equal to the operand on right side and returns 1 if true. For Example:

`Consider A = 20 and B = 10 A<=B would results 0`

## iii. is greater than or equal to

`>=`

operator :Checks whether the operand on left side is greater or equal to the operand on right side and returns 1 if true. For Example:

`Consider A = 20 and B = 10 A>=B would results 1`

### Program example of relational operators

```
//An example of relational operators
#include<stdio.h>
int main()
{
int A= 20, B=10;
printf("Consider A = %d and B = %d \n",A,B);
printf("is equal to operator (A==B) = %d \n",A==B);
printf("is not equal to operator (A!=B) = %d \n",A!=B);
printf("is greater than operator (A>B) = %d \n",A>B);
printf("is less than operator (A<B) = %d \n",A<B);
printf("is less than or equal to operator (A<=B) = %d \n",A<=B);
printf("is greater than or equal to operator (A>=B) = %d \n",A>=B);
return 0;
}
```

### Output

```
Consider A = 20 and B = 10
is equal to operator (A==B) = 0
is not equal to operator (A!=B) = 1
is greater than operator (A>B) = 1
is less than operator (A<B) = 0
is less than or equal to operator (A<=B) = 0
is greater than or equal to operator (A>=B) = 1
