Relational operator

Relational operators are used to find the relation between two variables. i.e. to compare the values of two variables in a C program.

Operators	Example/Description
>	x > y (x is greater than y)
<	x < y (x is less than y)
>=	x >= y (x is greater than or equal to y)
<=	x <= y (x is less than or equal to y)
==	x == y (x is equal to y)
!=	x != y (x is not equal to y)

EXAMPLE PROGRAM FOR RELATIONAL OPERATORS IN C:

• In this program, relational operator (==) is used to compare 2 values whether they are equal are not.
• If both values are equal, output is displayed as ” values are equal”. Else, output is displayed as “values are not equal”.
• Note : double equal sign (==) should be used to compare 2 values. We should not single equal sign (=).

C

1 2 3 4 5 6 7 8 9 10 11 12 13 14

#include <stdio.h>   int main() {    int m=40,n=20;    if (m == n)    {        printf("m and n are equal");    }    else    {        printf("m and n are not equal");    } }

OUTPUT:

m and n are not equal
