LeeCode-Number of 1 Bits

Write a function that takes an unsigned integer and returns the number of ’1' bits it has

For example, the 32-bit integer ’11' has binary representation 00000000000000000000000000001011,

so the function should return 3.

 int hammingWeight(uint32_t n)
 {
     int count=;
     while(n)
     {
         n=n&(n-);
         count++;
     }
     return count;
 }
