C++ - Decimal to binary converting

Question

I wrote a \'simple\' (it took me 30 minutes) program that converts decimal number to binary. I am SURE that there\'s a lot simpler way so can you show me? Here\'s the code:<

Answer 1

std::bitset has a .to_string() method that returns a std::string holding a text representation in binary, with leading-zero padding.

Choose the width of the bitset as needed for your data, e.g. std::bitset<32> to get 32-character strings from 32-bit integers.

#include 
#include 

int main()
{
    std::string binary = std::bitset<8>(128).to_string(); //to binary
    std::cout<(binary).to_ulong();
    std::cout<

EDIT: Please do not edit my answer for Octal and Hexadecimal. The OP specifically asked for Decimal To Binary.
