Default code in C++ for VSCode

Sure, here is a response:

#include <iostream>

int main() {
    std::cout << "Hello, world!" << std::endl;
    return 0;
}

Explanation: - #include <iostream>: This line includes the Input/Output Stream Library, which allows us to perform input and output operations in C++. - int main() { ... }: This is the main function where the program begins its execution. - std::cout << "Hello, world!" << std::endl;: This line outputs the text "Hello, world!" to the standard output (usually the console). - return 0;: This line indicates that the program has terminated successfully.
