Why pointers

Recently I’m messing around with historical code in my lab, written in c++. Dealing with pointers is inevitable. As I’m not a c++ native,pointers give me some trouble.

Then I run into this post, which explains all those gimmicks behind the widely abused used pointers. Good read.

The basic idea behind pointer is simple: a variable that stores the address of another variable.

But when pointers were used to implement features which c lack, pointers quickly became a nightmare to haunt innocent young programmers like me.

I’ve also noticed a trend in SO, regarding the same problem in different language, c/c++ programmers do like re-inventing the wheels:

in C/C++: “how do I do dis”

in R/python/whatever: “How do I do dat”


Oh, and I also learned to use makefile.
