2.1 Introduction In this problem, you are required to implement a word counter with two processes to automatically count the number of words in text files (with suffix .txt). You should achieve this with a C program that uses two processes (named parent process and child process respectively, both of which use only one thread). …

COMP2017 / COMP9017 Tutorial 2 Addressable Memory and Standard Library Functions The Preprocessor and Function Prototypes The preprocessor is part of the compilation pipeline that allows functions from separate translation units to be utilised in your source files and linked together. We are also able to define compile time constants and compile code based on …

COMP2017 / COMP9017 Tutorial 3 Structs, Unions, Bitfields and Files Structs and Unions Within C you can declare a new ‘type’ using structs. A struct is a collection of existing types with a constant size in memory defined at the time of compilation, and with a packing that is consistent within the architecture of the …

COMP2017 Week 5 Tutorial Dynamic Memory One of the most important uses of dynamic memory is to create a dynamically sized array at run time. Up until C99 it was impossible to do this without calling malloc. For an array with some length ‘length’, we can create a dynamically sized array as follows: int* my_arr …
Memory Allocator with FIFO Free List Create your GitHub repo for this lab here: https://classroom.github.com/a/eMu4D7oX In this lab, we’ll build our own memory allocator that serves as an alternative to the default malloc family of functions. If we take a look at the man pages for malloc et al., we’ll find that we need to …
