Common Mistakes to Avoid

Forgetting to Free Memory

One common mistake is neglecting to free memory allocated with malloc or similar functions. Beginners often overlook this, leading to memory leaks that can crash programs. To avoid this, always use free() after you're done with allocated memory, ensuring efficient memory management.

Incorrect String Handling

Many beginners mistakenly allocate insufficient memory for strings. For example, using malloc(strlen(src)) instead of malloc(strlen(src) + 1) can cause undefined behavior. Always remember to allocate an extra byte for the null terminator when dealing with strings.

Misunderstanding Array Decay

New programmers often confuse the types of arrays and pointers. For instance, passing a two-dimensional array to a function expecting a pointer can lead to errors. Understanding the difference between Type and Type[M][N] is crucial to avoid compilation issues.

Improper Use of scanf

Using scanf without proper input handling can lead to unexpected behavior, such as leaving newline characters in the input buffer. This can cause subsequent input functions to fail. Instead, consider using fgets for safer input handling.
