Tag: inequality operator

Relational Operators in C programming language return true(non-zero number) or false(0) value. They operate on 2 operands.

Relational Operators

== equality operator.
!= inequality operator.
> greater than operator.
< less than operator.
>= greater than or equal to operator.
<= less than or equal to operator.

== equality operator

 
#include < stdio.h >

int main()
{
    //Relational Operators

    int a = 10, b = 10;
    int temp;

    temp = (a == b);

    printf("value of temp is %d\n", temp);

    return 0;
}

Output:
value of temp is 1

 
#include < stdio.h >

int main()
{
    //Relational Operators

    int a = 10, b = 20;
    int temp;

    temp = (a == b);

    printf("value of temp is %d\n", temp);

    return 0;
}

Output:
value of temp is 0

!= inequality operator

 
#include < stdio.h >

int main()
{
    //Relational Operators

    int a = 10, b = 10;
    int temp;

    temp = (a != b);

    printf("value of temp is %d\n", temp);

    return 0;
}

Output:
value of temp is 0

 
#include < stdio.h >

int main()
{
    //Relational Operators

    int a = 10, b = 20;
    int temp;

    temp = (a != b);

    printf("value of temp is %d\n", temp);

    return 0;
}

Output:
value of temp is 1

> operator

 
#include < stdio.h >

int main()
{
    //Relational Operators

    int a = 20, b = 10;
    int temp;

    temp = (a > b);

    printf("value of temp is %d\n", temp);

    return 0;
}

Output:
value of temp is 1

< operator

 
#include < stdio.h >

int main()
{
    //Relational Operators

    int a = 20, b = 10;
    int temp;

    temp = (a < b);

    printf("value of temp is %d\n", temp);

    return 0;
}

Output:
value of temp is 0

>= operator

 
#include < stdio.h >

int main()
{
    //Relational Operators

    int a = 20, b = 10;
    int temp;

    temp = (a >= b);

    printf("value of temp is %d\n", temp);

    return 0;
}

Output:
value of temp is 1

<= operator

 
#include < stdio.h >

int main()
{
    //Relational Operators

    int a = 20, b = 10;
    int temp;

    temp = (a <= b);

    printf("value of temp is %d\n", temp);

    return 0;
}

Output:
value of temp is 0

Scanf(): For user input

In above c program we are asking user to enter the values for variable a and b. You can know more about scanf() method/function in this video tutorial: Using Scanf in C Program

Relational Operators In C

Note: = is assignment operator. == is equality operator.
