Count Set Bits in an Integer

Code

#include <stdio.h>

int countSetBits(unsigned int n) 
{
    unsigned int count=0;
    unsigned int t = n;
    while(t>=1)
    {
        if((t%2)!=(0))
        {
            count++;
        }
        t = (t/2);
              
    }

    return count;
}

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