Bit Toggle

#include <stdio.h>

int toggleFifthBit(int n) {
    // Write your code here
        int bit = (n >> 5) & 1;

    if (bit)
    {
        n &= ~(1 << 5);
    }
    else
    {
        n |= (1 << 5);
    }

    return n;
}

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

1. extract bit 5: int bit = (n >> 5) & 1;
2. if it is 1, reset it:     if (bit)
       {
           n &= ~(1 << 5);
       }
3. if it is 0, set it:     else
       {
           n |= (1 << 5);
       }
4. return the value: return n;
