What are some common Valgrind error messages I might encounter in C++?
Common Valgrind error messages include 'Invalid read', 'Invalid write', and 'Memory leak detected'. Each indicates a specific issue.
What does 'Invalid read' mean?
'Invalid read' means your program is trying to read memory that it shouldn't, often due to accessing uninitialized or freed memory.
How can I fix a memory leak?
To fix a memory leak, ensure that every allocated memory block is properly deallocated using 'delete' or 'free' when it's no longer needed.
Can Valgrind help with performance issues too?
Valgrind primarily focuses on memory management issues, but it can also help identify performance bottlenecks with tools like 'Callgrind'.
