Relational Operators in C Language

Relational operators in C Language:

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

S.no	Operators	Example	Description
1	>	x > y	x is greater than y
2	<	x < y	x is less than y
3	>=	x >= y	x is greater than or equal to y
4	<=	x <= y	x is less than or equal to y
5	==	x == y	x is equal to y
6	!=	x != y	x is not equal to y

Example program for relational operators in C language:

• 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

#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

 Continue on types of C language operators:

S.no	Types of Operators	Description
1	Arithmetic_operators	These are used to perform mathematical calculations like addition, subtraction, multiplication, division and modulus
2	Assignment_operators	These are used to assign the values for the variables in C programs.
3	Relational_operators	These operators are used to compare the value of two variables.
4	Logical operators	These operators are used to perform logical operations on the given two variables.
5	Bit wise operators	These operators are used to perform bit operations on given two variables.
6	Conditional (ternary) operators	Conditional operators return one value if condition is true and returns another value is condition is false.
7	Increment / decrement operators	These operators are used to either increase or decrease the value of the variable by one.
8	Special operators	&, *, sizeof( ) and ternary operators
