Relational operators in c programming; Through this tutorial, you will learn about relational operators in c programming and how to use them in c programs.
Relational Operators In C Programming
A relational operator checks the relationship between two operands. If the relation is true, it returns 1; if the relation is false, it returns value 0.
The below table shows all the Relational Operators in C programming with examples.
| Operator | Meaning of Operator | Example |
|---|---|---|
| == | Equal to | 7 == 3 is evaluated to 0 |
| > | Greater than | 7 > 3 is evaluated to 1 |
| < | Less than | 7 < 3 is evaluated to 0 |
| != | Not equal to | 7 != 3 is evaluated to 1 |
| >= | Greater than or equal to | 7 >= 3 is evaluated to 1 |
| <= | Less than or equal to | 7 <= 3 is evaluated to 0 |
Note that:- Relational operators are used in decision making and loops.
Example 1 – Relational Operators
// Working of relational operators
#include <stdio.h>
int main()
{
int a = 5, b = 5, c = 10;
printf("%d == %d is %d \n", a, b, a == b);
printf("%d == %d is %d \n", a, c, a == c);
printf("%d > %d is %d \n", a, b, a > b);
printf("%d > %d is %d \n", a, c, a > c);
printf("%d < %d is %d \n", a, b, a < b);
printf("%d < %d is %d \n", a, c, a < c);
printf("%d != %d is %d \n", a, b, a != b);
printf("%d != %d is %d \n", a, c, a != c);
printf("%d >= %d is %d \n", a, b, a >= b);
printf("%d >= %d is %d \n", a, c, a >= c);
printf("%d <= %d is %d \n", a, b, a <= b);
printf("%d <= %d is %d \n", a, c, a <= c);
return 0;
}
Output
5 == 5 is 1 5 == 10 is 0 5 > 5 is 0 5 > 10 is 0 5 < 5 is 0 5 < 10 is 1 5 != 5 is 0 5 != 10 is 1 5 >= 5 is 1 5 >= 10 is 0 5 <= 5 is 1 5 <= 10 is 1
Note that:- Relational operators in C are commonly used to check the relationship between the two variables
Example 2 – C Relational Operators with If else Statement
/* C Relational Operators in If Condition */
#include <stdio.h>
void main()
{
int x = 10;
int y = 25;
if (x == y)
{
printf(" x is equal to y \n" );
}
else
{
printf(" x is not equal to y \n" );
}
}
Output
x is not equal to y
