C++ conversion

Question

How would you convert an int to string in C++?
/******************************************************************************************************\
Edit: itoa worked but it made the numbers be in a char array, i wanted it to be a string, to fit my project(Getting a squared number, turning into a string to get the middle numbers then turning these middle numbers into an int and so on), if anyone came here to see the answer and have the same problem, use:

#include <sstream> //We need this lib
using namespace std; //So we dont use std::

int i = 12; //Any int value, can be double(I think)

ostringstream buffer; //we need sstream for this

buffer << i; //put the number in the var

string numString= buffer.str(); //conversion happens here

Answer 1

On desktop compilers, you may use itoa() function.

Answer 2

int variable = 5;
std::string foo = std::to_string(variable);

Answer 3

I got it to work with the itoa, but if you are planning to use itoa() function, don't use it on this website's compiler, it doesn't work on here for some reason.

Answer 4

the only way I know is what is called "type casting". I only used it once or twice, but it's pretty well documented online

Answer 5

I can't remember what language it belongs to, but I know there is also a function called "stringify", I'm just not sure if that was in c++ or not

Answer 6

Could you provide me a link or an example so I can look at it myself?

Answer 7

I found an even easier way, cplusplus.com states that there are functions provided to do specifically what you need to do in the string library. http://www.cplusplus.com/articles/D9j2Nwbp/

Answer 8

I tried the first example as it seemed the easiest and less confusing, but I get this error:
..\Playground\:10:15: error: aggregate 'std::ostringstream convert' has incomplete type and cannot be defined
ostringstream convert;

Answer 9

Did you import the string library?

@Jakub Stasiak
Error: to_string is not a member of std
Error2: to_string was not declared in this scope
@Ethan
Yes, I did import the string lib
