This task will involve understanding the use way in which virtual method dispatch works, and how it is implemented. Answer the following questions:
- Why aren't all functions made virtual in C++?
- What is a vtable?
- Use g++ to get the mangled name of the function. What is the mangled name?
- Use c++filt to get the de-mangled name of the function. What is the demangled name?
Create a tarball consisting of a single directory with all of your work in it,
such as code or written answers.
If you have any auxiliary files (READMEs, Makefiles, etc.), be sure
to include those as well.
Name your work directory
l9 and name
Upload your tarball to the L9 Canvas assignment.
Labs will be graded under one of following criteria:
- Effort: You will automatically be given full credit for the labwork if the GTA determines that your participation in the lab was meaningful - i.e. you attended the lab session and used the time to make a good-faith attempt to complete the work. It is the sole discretion of the GTA to determine if you put in sufficient effort. Even if you expect an effort-based grade, you should turn in your (possibly incomplete) work.
- Correctness: If you do not participant meaningfully in lab (i.e. you do not attend the lab session), your grade will be assessed based on the correctness of your lab submission.
The two-criteria grading scheme above is designed to avoid wasting your time. You should not feel obligated to attend the lab, and in fact should only do so if you want help from the GTA on the labwork assignment or whatever project is currently in progress. Here's a handy flowchart for how I suggest you approach lab:
