Common Mistakes to Avoid

Using gets()

One common mistake is using gets() for input, which is unsafe and can lead to buffer overflows. Beginners often overlook this due to its simplicity. Instead, use fgets() to ensure safety and prevent potential vulnerabilities in your code.

Not Checking for Self-Assignment

Another frequent error is neglecting to check for self-assignment in operator overloading. Beginners may forget this step, leading to unexpected behavior. Always include a check like if (&other == this) to avoid issues when assigning objects to themselves.

Improper Memory Management

Failing to set pointers to NULL after deletion is a common pitfall. New programmers might not realize the risks of dangling pointers. Always set pointers to NULL after using delete or free to prevent accidental reuse and memory leaks.

Ignoring Constants

Many beginners overlook the importance of defining constants properly. Using #define can lead to hard-to-debug issues. Instead, use const for defining constants, which provides type safety and better readability in your code.
