Why this one create wrong answer?

    uint32_t reverseBits(uint32_t n) {
            uint32_t res;
            if(n&1==0) res=0;
            else res=1;
            for(int i=1;i<32;i++){
            return res;

    If I made some modification on the if statement, it is correct. Can anyone tell me why this happened? Thanks.

    if(n&1==1) res=1;
    else res=0;

    Check out Operator precedence table, and you should find out why.
