Question

Is this example code valid?

std::string x ="There are";
int butterflies = 5;
//the following function expects a string passed as a parameter
number(x + butterflies + "butterflies");

The main question here is whether I could just pass my integer as part of the string using the + operator. But if there are any other errors there please let me know 🙂

Answer 1

A safe way to convert your integers to strings would be an excerpt as follows:

#include <string>
#include <sstream>

std::string intToString(int x)
{
  std::string ret;
  std::stringstream ss;
  ss << x;
  ss >> ret;
  return ret;
}

Your current example will not work for reasons mentioned above.
