LOGICAL OPERATORS IN C

Logical Operators in C

In C programming, the logical programming are used to perform logical operations like a boolean values that are either true or false. The three logical operators are:  

&&  logical AND : Returns true if both operands are true.

||      logical OR : Returns true if at least one of the operands is true.

!      logical NOT : Returns the opposite boolean values of the operand.

Examples for logical AND (&&) operator:

Program 1:

#include<stdio.h>
int main()
{
    int a,b;
    a=10; // true
    b=20; // true
    printf("The value for AND operator:%d",a&&b);
}

Output:

The value for AND operator:1

Program 2:

#include<stdio.h>
int main()
{
    int a,b;
    a=1; // true
    b=0; // false
    printf("The value for AND operator:%d",a&&b);
}

Output:

The value for AND operator:0

Examples for logical OR (||) operator:

Program:

#include<stdio.h>
int main()
{
    int a,b;
    a=10; // true
    b=0; // false
    printf("The value for OR operator:%d",a||b);
}

Output:

The value for OR operator:1

Examples for logical NOT(!) operator:

Program:

#include<stdio.h>
int main()
{
    int a,b;
    a=1; // It gives opposite value 0
    b=0; // It gives opposite value 1
    printf("The value for NOT operator:%d",!a);
}

Output:

The value for NOT operator:0
