What you will learn

  • Describe pointer validity and release responsibilities.
  • Build and test several translation units together.
  • Handle allocation and file failures deliberately.

  1. Pointers, Object Lifetime, and Aliases

    Reason about what a pointer may designate, how long that object exists, and which operations stay within its bounds.

    Start learning

  2. Dynamic Allocation and Ownership

    Design allocation, resizing, and cleanup as one ownership protocol, including every failure path.

    Start learning

  3. Structures and Data Models

    Group related values without confusing an in-memory representation with ownership, equality, or an external file format.

    Start learning

  4. Files, Streams, and Error Handling

    Handle a file as a fallible resource and preserve the difference between end of input, invalid data, and I/O failure.

    Start learning

  5. Modules, Headers, and Reproducible Builds

    Give components one source of interface truth and understand how declarations, definitions, and build dependencies fit together.

    Start learning

  6. Testing, Diagnostics, and Debugging

    Combine executable checks with contract reasoning, and investigate the first point where a program violates its invariant.
