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);
	multiplyBy8(10);
	multiplyBy8(7);
	multiplyBy8(-3);
	return 0;
}

Output

 (6 x 8) 48
 (10 x 8) 80
