Converting int[] to String in C++

Question

I have a string defined as std::string header = \"00110033\"; now I need the string to hold the byte values of the digits as if its constructed like this

Answer 1

you could write a little function

string int_array_to_string(int int_array[], int size_of_array) {
  string returnstring = "";
  for (int temp = 0; temp < size_of_array; temp++)
    returnstring += itoa(int_array[temp]);
  return returnstring;
}

^untested!

a slightly different approach

string int_array_to_string(int int_array[], int size_of_array) {
  ostringstream oss("");
  for (int temp = 0; temp < size_of_array; temp++)
    oss << int_array[temp];
  return oss.str();
}
