Learning to program: A starter guide to stacks and command-line calculators
Curious about how old-school Unix tools can sharpen your programming skills today? This guide walks you through the classic dc command-line calculator, showing how Reverse Polish Notation (RPN) and stacks, power its design. You’ll not only explore the fundamentals, but also build your own simplified version of dc in C—managing input, math operations, and stack manipulation along the way.
It’s a hands-on way to strengthen your command-line chops while deepening your understanding of core programming concepts.
