SOLID principles: from C++ classes to plain C
· 19 min read
Five letters that every job interview in software engineering seems to contain. S, O, L, I and D. The principles were described for object oriented languages, so the common conclusion is "SOLID is for C++ and Java, we write C, so we are done". That conclusion is wrong, and I will try to show why. For every principle you will find the original idea with a C++ example, and then the same idea in C, without classes, without inheritance and without a single virtual.
