How to convert an integer to a string [duplicate]

Question

I want to convert an integer to a string. I tried it this way but this didn't work

void foo()
{
    int y = 1;
    string x = static_cast<string>(y);

}

Answer 1

The std::to_string function should do it:

string x = std::to_string(y);

For the opposite, it's std::stoi:

int z = std::stoi(y, nullptr, 10);

Answer 2

No that will not work since int and std::string are not related in any class heirarchy. Therefore a static_cast will fail.

An easy way (though not necessarily the fastest way) is to write

std::stringsteam ss;
ss << y;
std::string x = ss.str();

But, if you have a C++11 compiler, Joachim Pileborg's solution is much better.

Answer 3

Can have this :

  template <typename T>
  string CovertToString ( T Number )
  {
     ostringstream ss;
     ss << Number;
     return ss.str();
  }
