In the previous article we covered C conditionals theory. Now it’s time to write real programs. In this article we build three programs from scratch using gedit and gcc in Fedora — a grade classifier, a number guessing game and a calculator with a menu. Each one uses if/else if/else and switch in situations where…
Conditionals in C if else switch work with the same logic as Python — same concept, different syntax. If you understood if/elif/else in Python, you already understand how decisions work in C. What changes is the notation: curly braces instead of indentation, else if instead of elif, and a switch that works identically to the…
Types and variables in C exercises are where printf, scanf and the type system stop feeling foreign. You’ve seen the theory and built three complete programs. Now it’s time to solve challenges on your own in Fedora. In this article you’ll find four exercises across three levels — from a BMI calculator to geometric shapes,…
In the previous article we covered types and variables in C theory. Now it’s time to write real programs. In this article we build three programs from scratch using gedit and compile them with gcc in Fedora, the exact workflow you’ll use in every IC2 lab. Each program uses all the main types and shows…
Types and variables in C are the first real shock when you move from Python to C in IC2. In Python you wrote x = 5 and Python figured everything out. In C you have to declare the type, the size and the format specifier for every variable, and if you get any of them…
Setting up C in Fedora is the first practical step in IC2. Before you write a single line of C code you need two things: a text editor to write the code and a compiler to turn it into an executable program. In Fedora that means gedit and gcc. This article walks you through the…
