Answer 1

If you're using the C++11 standard or newer (Code Playground doesn't), just #include <string> and use to_string():

int a = 10;
String str = to_string(num);

Otherwise you can #include <sstream> and work with a stringstream:

int a = 10;
stringstream ss;
ss << a;
string str = ss.str();

If you want to reuse the stringstream, write the following to empty it:
ss.str(string()); // string() is an empty string

Actually, Code Playground supports to_string now.

Answer 3

If you don't want to use library code or you own wish to use strings that you process, this code provides both options. I coded it a while ago, but got interrupted so I didn't post it here.

hey there my friend use should use string header file which is normally not a standard c++ header file but from c++ 11th standard all compilers have it

to covert into to string
u need to use to_string() function

eg:
#include<string>
int n;
void main()
{
cin>>n;
String n=to_string(n);
}

but u should know some bit about string class u can't use char array since to_string() return String type

which is a class in string header file

sorry for a little big answer
