C Programming Tutorial Tricks and Recursion Recipes

Short-form recipes for recursion, optimization, and practical C and C++ coding patterns.

Every entry in /tricks is a short-form recipe for the hard parts inside the notebooks — recursion, optimizations, defensive I/O patterns, and other practical hacks.

• Recursive base cases: explicit guard blocks with early returns to keep stack depth under control.
• Tail recursion notes in C: convert to iteration by reusing local buffers so that compilers can optimize.
• Divide & conquer: map a problem to halves, derive recurrence, and estimate the stack footprint before coding.
• Stack diagrams: draw function frames with parameter values to debug tricky call orders.

These pocket recipes live outside the core notebooks so they can stay concise while still powering every project and example.

Use them as a supplement during practice, interviews, and while extending the CLI projects.
