Common Pitfalls

• Pitfall: Misunderstanding pointer arithmetic can lead to segmentation faults and memory access violations during array manipulation exercises. To avoid this, always verify pointer bounds and use printf debugging to trace memory addresses step by step.
• Pitfall: Forgetting to free dynamically allocated memory results in memory leaks that compromise program efficiency and stability. Develop a habit of pairing malloc() with free() and tracking allocations systematically throughout your code.
• Pitfall: Overlooking null terminators in C strings causes unexpected behavior in input/output operations and string processing. Always ensure buffers are properly sized and terminated, especially when reading user input with functions like scanf().
• Pitfall: Incorrectly implementing recursive functions without base cases leads to infinite loops and stack overflow errors. Always define clear termination conditions and test recursion depth with small inputs before scaling up.
• Pitfall: Ignoring compiler warnings often masks subtle bugs that only appear during runtime execution. Treat all warnings as errors and resolve them immediately to build robust and reliable programs.
• Pitfall: Copying code without understanding leads to poor retention and inability to debug independently. Instead, type every example manually and modify it slightly to observe how changes affect behavior.
• Pitfall: Skipping the Seven Steps problem-solving method results in disorganized code and inefficient solutions. Always follow the structured approach to break down problems before writing any code.
