Showcase

Small C programming exercises from my early CS50 learning phase.

Contents

• credit.c: credit card validator using Luhn's algorithm
• readability.c: Coleman-Liau readability index calculator
• substitution.c: substitution cipher tool

Build Requirements

These files use the CS50 library (cs50.h), so compile with CS50 tooling.

Example:

clang credit.c -lcs50 -lm -o credit
clang readability.c -lcs50 -lm -o readability
clang substitution.c -lcs50 -lm -o substitution

Why This Repo Exists

This repository is kept as a record of my first programming projects and learning progression.
