I spend the coding session cleaning the project from needed lines of code and looking for bugs. I ended up finding a bug where if there were multiple URLs, then, the last one only was being executed.
I tried to create a vector to push back threads into it but had a linker error because I didn't initialize it. I got stuck because I was unsure how to initialize a vector of thread objects.
So, for the next session, I must find a solution to this thread issue.
