What is the easiest way to convert from int to equivalent string in C++?
I am aware of possible methods. Is there any easier way to implement it?

int a = 10;

char *intStr = itoa(a);

string str = string(intStr);

stringstream ss;

ss << a;

string str = ss.str();

I normally apply the following process:

#include <sstream>



template <typename T>

  std::string NumberToString ( T Number )

  {

     std::ostringstream ss;

     ss << Number;

     return ss.str();

  }

We also had to_string() built-in method in c++ that accepts a value of any basic data type and converts it into a string.

Below is an example:

#include <iostream>
#include<string>
using namespace std;

int main() {
int num = 100; // a variable of int data type

string str; // a variable of str data type
str = to_string(num); // using to_string to convert an int into a string
cout << "The integer value is " << num << endl;
cout << "The string representation of the integer is " << str << endl;
}
