You should be comfortable with C pointers, <code>malloc</code>/<code>free</code>, and basic struct usage before working through the code here.<h2>Big Picture</h2>Knowing what a stack does is half the picture. The other half is knowing how to build one in C. This set of notes walks through three implementations you are likely to see on an exam: an array-based stack, a linked list-based stack, and a practical application (balanced…
