Step 1: Remainder when 10 is divided by 2 is zero. The standard solution to convert a number to its binary format in C++ is using std::bitset.The idea is to construct a bitset container object with the bit values of the specified number and invoke the to_string function to get a std::string representing the bits in the bitset, with leading-zeros.
