Teaching/refreshing myself the essential elements of C, to build experience with the underlying functional structures of software and the limitations of low-level languages. Long-term plan is to translate knowledge of C into other "modern" descendants of the C family (Go, etc.).
Lessons and problems are based on Stephen Kochan's "Programming in C", with the folders number accordingly
All basic aspects of the language were covered, with particular emphasis placed on:
'char' arrays and their limitations vis-a-vis modern implementations of strings
'pointers' and their importance for memory manipulations
'bitwise' operations and what they reveal about underlying 32 and 64-bit processor architectures
