<ul><li>The given problem is to count the number of set bits in a given number when represented in binary format.</li><li>Two methods to solve this problem are by using the inbuilt library function and by using bit manipulation.</li><li>The first method makes use of the bitset<32>() function in C++ to convert the number to binary and then uses the count() method to find the number of set bits.</li><li>The second method involves using bitwise and (&) and right shift (>>) operations to check and count the set bits.</li></ul>
