C Programming Fundamentals: Pointers, Memory and Files

What you'll learn

• Compile and run C programs and use variables, types and control flow.
• Write functions, arrays and strings and handle input safely.
• Use pointers, pointer arithmetic and function pointers confidently.
• Model data with structs, unions and enums and manage heap memory without leaks.
• Read and write files, use the preprocessor and debug with gdb and sanitizers.
