Easiest way to convert int to string in C++

Question

What is the easiest way to convert from int to equivalent string in C++. I am aware of two methods. Is there any easier way?

Answer 1

Using stringstream for number conversion is dangerous!

See http://www.cplusplus.com/reference/ostream/ostream/operator%3C%3C/ where it tells that operator<< inserts formatted output.

Depending on your current locale an integer greater than 3 digits, could convert to a string of 4 digits, adding an extra thousands separator.

E.g., int = 1000 could be convertet to a string 1.001. This could make comparison operations not work at all.

So I would strongly recommend using the std::to_string way. It is easier and does what you expect.

Updated (see comments below):

C++17 provides std::to_chars as a higher-performance locale-independent alternative
