Study Notes
Introduction to Computer Systems and C Programming
- CMSC 216 Introduction to Computer Systems is a course that covers basic Unix commands and C programming.
- Lectures are recorded and posted online, there are no pop quizzes, and no collaboration on projects is allowed.
- The website sign-in for the course is cmsc216/sprcoredump, and office hours are immediately after class in IRB 2210.
- Everyone in the course will receive an Arduino to be used later in the course.
- Unix commands such as pwd, ls, ls -al, ls -F, and cd are useful for writing and executing C programs.
- C programming in CMSC216 is different from Java as it is not object-oriented and lacks concepts of classes, objects, polymorphism, and inheritance.
- The #include allows the compiler to check argument types, and main() function is where all C programs begin, and return 0 is used to end the program.
- C programs need to be compiled before they can be executed, and the gcc compiler is used to compile a C program.
- Some more compilation options are -g, -Wall, and -o filename, which generate symbols, warn about common problems, and place an executable in the file name, respectively.
- Returning 0 in the main() function is independent of the void that appears in the main's header.
- Unix commands such as cp, rm, mv, and cat are useful for copying, removing, renaming, and displaying file contents, respectively.
- There are three compilation stages for C programs: preprocessor stage, translation stage, and linkage stage, which verify program parts, create an object file, and bring together one or more object files to create an executable file.
