# Multiply a number by 8 using bitwise operator

Here given code implementation process.

``````// C Program
// Multiply a number by 8 using bitwise operator
#include <stdio.h>

void multiplyBy8(int num)
{
// Shift given number to left by 3
int result = ((num) << 3);
// Display calculated result
printf(" (%d x 8) %d\n", num, result);
}
int main()
{
// Test
multiplyBy8(6);

#### Output

`````` (6 x 8) 48
