Toggle the last n bits

Here given code implementation process.

// C Program 
// Toggle the last n bits
#include <stdio.h>

// Change last n bits of a given number
void changeLNBits(int num, int n)
{
	// Display given number
	printf("\n Number : %d", num);
	// Change last n bit
	int result = num ^ (1 << n) - 1;
	// Display calculated result
	printf("\n After change last %d bits : %d\n", n, result);
}
int main()
{
	// (15) 1111 => 1000  n=3
	changeLNBits(15, 3);
	// (100) 1100100 => 1111011  n = 5
	changeLNBits(100, 5);
	// (10) 00001010  => 11110101 (1s) => 11110110 (2s)
