How do I reverse only the last 8 bits of an integer (32 bit) in C?

Question

I have implemented the below function in C but it is not working properly.

int reverse(int org_num){
   int rev_num=0;
   int i=1;
   while(i<=8){
       int last_bit=org_num&1;
       rev_num=rev_num|last_bit;
       rev_num=rev_num<<1;
       org_num=org_num>>1;

       i=i+1;
   }
   return rev_num; }

Answer 1

I solved the problem by breaking the loop for the last bit since that is not required.

    int reverse(int org_num){
       int rev_num=0;
       int i=1;
       while(i<=8){
          int last_bit=org_num&1;
          rev_num=rev_num|last_bit;
          if(i==8) {
            break;
          }
          rev_num=rev_num<<1;
          org_num=org_num>>1;
    
          i=i+1;
       }
       return rev_num;
   }
