Hello C++

Start with a tiny C++ program that stores a name and prints a greeting.

hello.cpp

#include <iostream>
#include <string>

int main() {
    std::string name = ;
    std::string message = "Hello, " + name + "!";

    std::cout << message << std::endl;
    return 0;
}

#include <iostream>
#include <string>

int main() {
    std::string name = ;
    std::string message = "Hello, " + name + "!";

    std::cout << message << std::endl;
    return 0;
}

#include <iostream>
#include <string>

int main() {
    std::string name = ;
    std::string message = "Hello, " + name + "!";

    std::cout << message << std::endl;
    return 0;
}

cout `std::cout` writes text so you can see what the program produced.
