CPSC 421-010 Object-Oriented Programming Spring 2026

The file Memory.cpp in the repository Memory contains many memory resource problems described in the notes.

Compile and run the program on your platform (i.e., your compiler and operating system). You may or may not see a memory-related issue during the build and run.

Go to a system where you can run valgrind. Following the instructions in the Guide: Valgrind, compile and run valgrind on the program.

Fix the memory resource problems in Memory.cpp by:

• Change or add additional new and delete operators
• Fix incorrect index values to fit the comment

Do this for each section one by one committing each section separately. Get the code to the point where it compiles and runs successfully, and you have a clean Valgrind run. For a commit message, use the verb "Fix" and the error given in the // @error comment.

If you do any of the following, your score will be a 0:

• Remove/add calls to producer() and consumer()
• Change producer() or consumer()
• Change the existing comments
• Use std::unique_ptr
• Add any functions
• Fix more than one block in a single commit
• Improper commit messages

Once done, tag this in Git as memoryfixed. Make sure to git push before you create the tag.

Note: The function consumer() is not just a function for deleting memory. That is not the entire purpose of consumer(). This is indicated by the:

which is the universal (code example) symbol for "Other processing will occur, but we are ignoring it for now to make a point". Some example of what could occur in producer/consumer, in addition to memory allocation/deallocation:
