Common Mistakes to Avoid

Ignoring Compiler Optimization Options

Many beginners overlook the importance of compiler optimization options. This mistake often stems from a lack of understanding of how these options can enhance performance. To avoid this, always review and enable relevant optimization flags in your compiler settings, such as -O2 or -O3, to maximize efficiency.

Overusing Dynamic Memory Allocation

New developers frequently rely on dynamic memory allocation, which can lead to performance bottlenecks. This occurs because managing memory on the heap incurs overhead. Instead, prefer stack allocation or fixed-size arrays where possible, as they are faster and more efficient.

Neglecting Code Profiling

Failing to profile code before optimization is a common pitfall. Beginners often optimize based on assumptions rather than data, leading to wasted effort. Use profiling tools to identify bottlenecks and focus your optimization efforts where they will have the most impact.

Using Inefficient Data Structures

Choosing the wrong data structures can severely impact performance. Beginners may not understand the trade-offs between different structures. To avoid this, familiarize yourself with the characteristics of various data structures and select the most appropriate one for your specific use case.
