Programming in "C‟ | List various logical operators and describe use of each with suitable example.

The logical operators are:

&&-logical AND

|| - logical OR

! – logical NOT

&&-logical AND. Used when we want more than one condition to be checked and also the statements should be executed only if all the conditions are true.

Eg : for &&(and)

#include<stdio.h>

#include<conio.h>

void main() {

int i,j;

clrscr();

printf("Enter two values");

scanf("%d%d",&i,&j);

if(i<=5 && j<=7)

printf("i and j are less than 5");

getch();

}

|| - logical OR - Used when we want more than one condition to be checked and also the statements should be executed if either of the conditions are true.

Eg: for ||(or)

#include<stdio.h>

#include<conio.h>

void main() {

int i,j;

clrscr();

printf("Enter two values");

scanf("%d%d",&i,&j);

if(i<5 || j<7) {

printf("The values are%d%d",j,j);

}

getch();

}

! – logical NOT – used we want to negate a condition.

Eg: for !(Not)

#include<stdio.h>

#include<conio.h>

void main() {

int i,j;

clrscr();

printf("Enter two values");

scanf("%d%d",&i,&j);

if(!(i<=5 && j<=7)) {

printf("the values are %d%d",i,j);

}

getch();

}
