My program converts decimals to binary, hex etc. The output of the
binary numbers are to be in the form 0000 0000 for all numbers from 0

between each 4 bits?
You may use std::bitset to store the number, and use to_string member
function.
#include <string>
#include <bitset>
#include <iostream>
int main()
{
std::bitset<8> number(145);
std::string representation(number.to_string());
std::cout
<<representation.substr(0,4)<<' '
<<representation.substr(4)<<std::endl;
}
using bitset and its to_string()
in this way, you have to ignore all the heading '0's
No, because t to_string generates exactly eisht characters, as
requested by OP
Well,
if "0011 1100" is OK, then OK
I thought for a binary number it would prettier to write "11 1100"
