Statement of C Program: This Program illustrates the logical ANDing and ORing operations:

#include<stdio.h>

#include<conio.h>

void main()

{

int a , b , c;

clrscr();

a = 4 , b = 3;

c = a && b;

b = a||b||c;

a = a && b||c;

printf("%d" , a\n);

printf("%d" , b\n);

printf("%d" , c\n);

}

Output:

1

1

Example:

Let   a=2    b=4    c=3

Solve the Logical Expression:     a && b||c && (!b)

Solution:

2 && 4||3 && (!4)

2 && 4||3 && (0)

1||3 && 0

1||0

Practise Questions:

What is the Output of the Following Programs:

1. 

main() 

{

int a = 10 , b = 12 , c = 15;

a = a && b || c;

b = a || b && c;

c = a && b && c;

printf("%d" , a\n);

printf("%d" , b\n);

printf("%d" , c\n);

}

2. 

 main() 

{

int x = 2 , y = 3 , s1 , s2 ;

s1 = x + (++y);

s2 = ++x + y++ ;

printf("%d\n%d\n" , s1 , s2);

}
