Left-shift an integer by two bits

Write a C program to shift given data by two bits to the left.

Sample Solution:

C Code:

#include<stdio.h>
int main() {
    int a, b;

    // Prompt user to input an integer
    printf("Read the integer from keyboard-");
    scanf("%d",&a);

    // Display the original integer value
    printf("\nInteger value = %d ",a);

    // Left shift 'a' by 2 bits and assign it to 'b'
    a <<= 2;
    b = a;

    // Display the left shifted data
    printf("\nThe left shifted data is = %d ",b);

    return 0;
}

Sample Output:

Read the integer from keyboard-
Integer value = 2 
The left shifted data is = 8
