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;
}
