Integer variables can be converted to strings using one of two methods. The two methods are described below along with a sample of the code.

Approach-1

#include<iostream> 

#include<string> 

using namespace std;

void main() 

{ 

     int n= 1; 

    string s= to_string(n); 

    cout << s;

}

Approach-2

#include<iostream> 

#include <sstream>  

#include <string> 

using namespace std; 

int main() 

{ 

     int n = 17; 

     // declaring output string stream 

     ostringstream s1; 

     // Sending a number as a stream into output str

     s<< n; 

     // the str() converts number into string 

     string fin = s.str(); 

     // Displaying the string

     cout << fin; 

     return 0; 

}
