int to string Using to_string method

To convert an integer to a string in C++, you can use the to_string method. Here are the steps involved:

  1. Include the necessary header file: To use the to_string function, you need to include the <string> header file in your C++ program.
#include <string>
  1. Declare an integer variable: Declare an integer variable that you want to convert to a string.
int num = 12345;
  1. Convert the integer to a string: Use the to_string function to convert the integer to a string. Pass the integer variable as an argument to the to_string function.
std::string str = std::to_string(num);
  1. Use the string variable: The converted string value will be stored in the str variable. You can now use this string variable in your program as needed.
std::cout << "The converted string is: " << str << std::endl;

Here's a complete example:

#include <iostream>
#include <string>

int main() {
    int num = 12345;
    std::string str = std::to_string(num);
    std::cout << "The converted string is: " << str << std::endl;
    return 0;
}

This program will output:

The converted string is: 12345

That's it! You have successfully converted an integer to a string using the to_string method in C++.
