• Guide: Valgrind

• Exercise 54: Memory

  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 without using std::unique_ptr. 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.

  Once done, tag this in Git as memoryfixed.

• Demo: Too many open files
• Notes: Dependencies

Unless otherwise noted, exercises are due by 4:30 pm on Mon, Mar 17 Wed, Mar 19.
