Brainfuck Interpreter in C - second day

Image
Hello everyone Yesterday I made some magic in our code and today I want to show you this. The most important thing that I wrote is the implementation of the linked list which can store all instructions from the file. Let's see what we already have. We have these functionalities: - a file has to be read as an argument - react if the file is not specified - react if the file extension is not right - react if the file is not found Today we will add these to our interpreter: - read brainfuck instructions from a file - check if the char from the file is brainfuck instruction - if it is brainfuck instruction then add it to the linked list
