SOFT3410 Tutorial 2 Standard Library, Files and Function Pointers Question 1: Files We are able to access files on your system using the file api functions and types. The FILE type is a portable abstraction for interacting with files and streams on your system. Once opened, you can use functionslikefwrite, fgets, fread, fputs, …toreadorwrite. int

SOFT3410 Tutorial 4 Measuring, Graphing and Techniques We will be looking into performance analysis of applications. We are mostly concerned with the cpu usage but we will check out memory usage. Question 1: Time Command To get a rough idea of the real time implications of our application, we can utilise a unix command to

SOFT3410 Tutorial 7 Atomics You have a quiz today and we will look into atomics Question 1: Atomic Operations, Counting and Stacks As we have noted prior, race conditions occur when we have more than one thread mutating shared memory. Atomics actually allow us to deal with this situation by making the write visible to
