Bit Toggle

Code

#include <stdio.h>

int toggleFifthBit(int n) {
    if(n>=0){
   if(n<32){
    n|=(1<<5);
   }
   else {
    n&=~(1<<5);
   }
    }
    else {
        n=-n;
     if(n<32){
    n|=(1<<5);
   }
   else {
    n&=~(1<<5);
   }
   n=-n;

    }
   return n;
}

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