C Program | Logical Operator

Example 1: Write a program to explain the Logical AND Operator(&&) 1

#include<stdio.h>
void main()
{
    int a;
    a = (10<20);
    printf("\n(10<20) = %d",a);
    a = (10>20);
    printf("\n(10>20) = %d",a);
    a = (10<=20);
    printf("\n(10<=20) = %d",a);
    a = (10>=20);
    printf("\n(10>=20) = %d",a);
    a = (10==20);
    printf("\n(10==20) = %d",a);
    a = (10!=20);
    printf("\n(10!=20) = %d",a);	
}

Example 2: Write a program to explain the Logical OR Operator(||). 1

#include<stdio.h>
void main()
{
    int a;
    a = (2<1) || (4<3);
    printf("\n(2<1) || (4<3) = %d",a);
    a = (2<1) || (4>3);
    printf("\n(2<1) || (4>3) = %d",a);
    a = (2>1) || (4<3);
    printf("\n(2>1) || (4<3) = %d",a);
    a = (2>1) || (4>3);
    printf("\n(2>1) || (4>3) = %d",a);
}

(2<1) || (4<3) = 0
(2<1) || (4>3) = 1
(2>1) || (4<3) = 1
(2>1) || (4>3) = 1

Example 3: Write a program to explain the Logical NOT Operator(!). 1

#include<stdio.h>
void main()
{
    int a;
    a = !(2<1);
    printf("\n!(2<1) = %d",a);
    a = !(2>1);
    printf("\n!(2>1) = %d",a);
}

!(2<1) = 1
!(2>1) = 0
