C/C++ [C++] Problems with strings MinGW

[utkarshakash]

I'm trying to convert an integer variable to a string using to_string function of string.h header file.
Here's the part of code:

string numToStr=to_string(num);

However, when I try to compile my program I get the following error:
"error:to_string was not declared in this scope"

I'm using CodeBlocks as my IDE and my compiler is MinGW 4.8.1-4. Can anyone tell me why is this error showing up and how to fix this issue?

string.h contains functions for C-style char* "strings", not C++ strings. Try using '#include <string>' instead of '#include <string.h>'. (or in addition to it, in case you're using both C-style and C++ strings.)

In addition to what jtbell said, you probably need to include the namespace std as in the example shown here: http://www.cplusplus.com/reference/string/to_string/.

string.h contains functions for C-style char* "strings", not C++ strings. Try using '#include <string>' instead of '#include <string.h>'. (or in addition to it, in case you're using both C-style and C++ strings.)

If you want to use the C string functions in a C++ program, #include <cstring> is cleaner than #include <string.h>. The same naming system applies to any other C standard headers you want to use in C++.

<string.h> is "really" C and not C++, even if your C++ compiler eats it without producing any error messages.

Of course you also need #include <string> to use the C++ string functions.
