Bit Toggle

Code

#include <stdio.h>

int toggleFifthBit(int n) {
    // Use XOR bitwise to solve this problem , according to XOR rule we can toggle
    //bit in reg if that bit XOR with the bit of 1. Example: 1 XOR 1 = 0, 0 XOR 1 = 1
    n = n ^ (1 << 5);
    return n;
}

int main() {
    int n;
    scanf("%d", &n);
    printf("%d", toggleFifthBit(n));
    return 0;
}
