C Fundamentals & Tooling

Compile C programs from the command line using gcc with standard warning flags (-Wall, -Wextra, -Werror).

Explain the purpose of separating a C program into multiple source (.c) and header (.h) files.

Use header guards to prevent multiple inclusion errors.

Explain C integer types (short, int, long, unsigned), their sizes, and verify with sizeof.

Predict and handle integer overflow behavior for signed and unsigned types.

Identify implicit type conversions and integer promotions in C expressions.

Write a number-based game (e.g., dice roller) using loops, conditionals, and functions as a warm-up.
