What are some common debugging errors in C++ and Java?

Common debugging errors in C++ include memory leaks, segmentation faults, and uninitialized variables. In Java, you might encounter null pointer exceptions, array index out of bounds, and class cast exceptions.

How can I fix a segmentation fault in C++?

To fix a segmentation fault, check for dereferencing null pointers, ensure proper memory allocation, and validate array indices.

What about null pointer exceptions in Java?

In Java, null pointer exceptions can be avoided by initializing objects before use and using optional types or null checks.

Are there tools to help with debugging in these languages?

Yes, tools like GDB for C++ and built-in debuggers in IDEs like Eclipse or IntelliJ for Java can help identify and fix errors.
