Is there a pre-defined built-in function to convert a number to its binary format in C++?

Question

Integer.toString(n,8) // decimal to octal

Integer.toString(n,2) // decimal to binary

Integer.toString(n,16) //decimal to Hex

We have these functions in java ... do we have such built-in functions in c++

Answer 1

You can use std::bitset to convert a number to its binary format.

Use the following code snippet:

  std::string binary = std::bitset<8>(n).to_string();
