It was my first day to class so having missed the first day I feel a little behind/overwhelmed but I'm working to catch up. From the notes I had taken, one concept of significance would be learning the printf format specifiers. Some concepts I'm dealing with that are not making perfect sense yet would be the unsigned, signed, short and long aspect. The challenges i'm facing as of now with respect to the course would be managing my overall workload. Figuring out how to manage my time will be a struggle until I get a system down that accounts for all the newly acquired work from this class.
