Is there a function or a formula to convert string"of letters" to hexadecimal in c++

Question

i tried to convert the string to ASCII but couldn't convert the ASCII to hex

#include <stream>
#include <string>
using namespace std;
int main()
{
    string x="hello";
    string x_as_cii[10];
  for(int i=0;i<x.length();i++)
  {
      x_as_cii[i]= int(x[i]);
      cout<<x_as_cii[i]<<endl;
   }
return 0;


}

What exactly do you mean by "ascii to hex"? The ascii string you have shouldn't convert to hex, as there is no "h", "l", or "o" in the hex character set. Maybe I'm missing something? — , Oct 17 '19 at 21:17

Boost.Algorithm has boost::hex (and the inverse boost::unhex), which should do what you want.
