C Program to Multiply given Number by 4 using Bitwise Operators

 

#include 

#include

void main()

{

    long number, tempnum;

    clrscr();

    printf("Enter an integer \n");

    scanf("%ld", &number);

    tempnum = number;

    number = number << 2;

    printf("%ld x 4 = %ld\n", tempnum, number);

    getch();

}

Output

Enter an integer

450

450 x 4 = 1800
