Question

Is there an easy way to append an integer to a string?

I have a for loop like this:

for (int i = 0; i < text.length(); i++) {
  for (int g = 0; g < word.length(); g++) {
    if (text[i] == word[g]) {
      kodas.append(g);
    }
  }
}

and I need to get the index of the array which is equal, and the index of course is an integer type. But as I do this I get an error:

invalid conversion from ‘int’ to ‘const char*’ [-fpermissive]|

is there a way to fix this?

Use stringstream if you are working with std::strings: #include <sstream>

#include <sstream>
using namespace std;
string oldString = "old";
int toAppend = 5;
stringstream ss(toAppend);
string newString = oldString + ss.str();

newString will be "old5"
