## C – Relational Operators

#### 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.
 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:

• 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

 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
