C++ basic

I just start playing around with C++ and how to combine it with Emacs. This website on cpp-programming and Intro to C++ are the starting point for me. The extended aim is to be able to write some C++ codes that can be part of R.

Standard Hello World!.

#include <iostream>

using namespace std;

int main(){
    cout << "Hello World!" << endl;
    return 0;
}

To compile this basic code in Emacs then use make with the following:

• M-x compile or SPC c c in Doom.
• type make basic. This will use Makefile to find basic.cpp file to compile and use g++.
• An executable file named basic will be produced.
• Run the file eg. ./basic
• If you alter the file then you can M-x recompile or SPC c C

A nice description on using Makefile can also be found here doc.ic.ac.uk
