Relational operators in C:
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 (=).

#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

Types of Operators

Description
|
| Arithmetic_operators | These are used to perform mathematical calculations like addition, subtraction, multiplication, division and modulus |
| Assignment_operators | These are used to assign the values for the variables in C programs. |
|
These operators are used to compare the value of two variables.
|
|
|
These operators are used to perform logical operations on the given two variables.
|
|
|
These operators are used to perform bit operations on given two variables.
|
|
|
Conditional operators return one value if condition is true and returns another value is condition is false.
|
|
|
These operators are used to either increase or decrease the value of the variable by one.
