The Evolution and Core Principles of C++

C++ is a powerful, object-oriented programming language that has played a significant role in software development since its inception. Developed by Bjarne Stroustrup at Bell Labs (now AT&T Labs) between 1983 and 1985, C++ built upon the foundations of the C language. C itself has a rich lineage, tracing back to the B language (1970) by Ken Thompson and ultimately to the BCPL language.

Test code example of cout, which should be highlighted, the using namespace call should also be highlighted:

// Hello World Application
#include <iostream>             // 1
using namespace std;            // 2

int main() {                    // 3
    cout << "Hello world!\n";   // 4
    return 0;                   // 5
}

Test rust code with a diff:

// Enum for messages in a game, with tuple-like data
enum Message {
    Quit, // No data
    Move(i32, i32), // Holds x and y coordinates
   Write(i32), // Holds a int message
   Write(String), // Holds a String message
    ChangeColor(i32, i32, i32), // Holds RGB values
}

What is true regarding the shortest valid C++ program?

derekmolloy.ie

It requires the iostream header.

It must contain a main() function.

It must explicitly return 0.

An empty method body is valid.
