Assignment

• Log in to the server.

• Copy the file mem.exe from the /public/classwork/week14/wed/ directory into your directory.

This assignment will be graded by hand.

Run mem.exe with valgrind. In a new file called mem.txt in your csci112_fall2023/classwork/week14/wed/ directory, answer the following questions:

1. How many memory errors are there?
2. How many memory leaks are there?
3. Describe the memory errors. What sort of thing do you think caused them? How do you know?
