The setting is a computer lab on campus. The assignment was due tomorrow and I was just finishing up the code. I was a novice at C and programming in general at that time. I finish the ~250 lines of functions or so but behavior of the simple library isn't right. I'm getting wrong values and I cannot find the source - I hate myself for not testing incrementally. Then, after looking for hours piece by piece while looking at references and StackO, I realized that I improperly dereferenced a pointer, something like *(this) instead of (*this) in a function. I didn't even know that I was making a mistake because I missed one of the relevant lectures. After that I realized that the errors thrown by the compiler weren't all that bad...
