How to convert int to string in C++?

In C++, you can convert an int to a string using the std::to_string() function from the <string> header. Here's how you can do it:

cpp

#include <iostream>
#include <string>

int main() {
    int number = 42;
    std::string numberString = std::to_string(number);

    std::cout << "Integer: " << number << std::endl;
    std::cout << "String: " << numberString << std::endl;

    return 0;
}

In this example, the std::to_string() function is used to convert the int variable number to a string called numberString. The resulting string can then be printed or manipulated as needed. The output of the program will be:

makefile

Integer: 42
String: 42

The std::to_string() function is convenient and commonly used when you need to convert numeric types to strings in C++.
