My professor required we make a LinkedList class with a bool add(in newEntry) method.
Two things I'm questioning my choices on is the variable name temporary and instances of how to return False if it isn't successfully added. Or is simply not returning True is going to return something False?

I wrote a method that finds the maximum sum of consecutive decreasing sequence of odd integers.
For example: if sequence is 13 9 7 12 13 15 13, then sum is 29 (13 + 9 + 7).

I would like to expose a nullable referance of a "mesh" object, so I am returning a const pointer. However, I explicitly want to prevent anyone handling this from deleting the object. The following is my solution.

In the following I reimplement the Walker-Vose Alias method for sampling from nonuniform, discrete probability distributions.
I am well aware that there is https://en.cppreference.com/w/cpp/numeric/random/discrete_distribution
which I would use for production code.
alias_lib.h contains the main logic.

size_t search_no_recursion(int *arr, int target, int start, int end) {
size_t middle;
while(start < end) {
middle = (start + end) / 2;
if(target == arr[m... |
