C projects

Three projects that pull your C together: a calculator, rebuilding printf and reviewing it with AI, then a simple shell from scratch.

OverviewThree C projects that pull together what you learned: a calculator, then your own printf reviewed with AI help, then a small shell from scratch.
Simple CalculatorYour first real C program that reads input, handles it with multi-branch logic and prints a result, pulling all of C's basics into one small program.
Rebuilding printf and Reviewing It with AI AssistanceYou build a simplified printf from scratch, then use AI as an extra reviewer (not a replacement) to improve it.
Building a Simple ShellThe hardest project of this track: a shell from scratch that reads commands and runs them, applying everything you learned about processes in the operating system.
