Today's starter for ten:

In C++, just how is one meant to go about transforming an integer into a string? Almost every other language I've used can do this in one statement, without having to preallocate the string.

If you're using STL:

int value = 42;
string string;

stringstream ss; // 1st statement
ss << value; // 2nd statement
ss >> string; // 3rd statement

If you're doing Windows programming with MFC:

int value = 42;
CString string;

string.Format("%d", value); // 1 statement
