change int to string cpp

To change an int to a string in C++, you can use the std::to_string() function. Here are the steps to do so:

1. Declare an int variable and assign it a value: cpp int num = 42;

2. Use the std::to_string() function to convert the int to a string: cpp std::string strNum = std::to_string(num);

3. The std::to_string() function takes the int value as an argument and returns a string representation of that value.

4. Now, strNum will contain the string representation of the int value 42.

5. You can use strNum as a regular string variable, performing string manipulation or printing it to the console as needed.

That's it! By following these steps, you can easily convert an int to a string in C++.
