    This week in CS107e

    Week 2
    Lecture
    Mon 4/6    		 From Assembly to C ( slides, code )

    Moving up from assembly to C. Implementation of C expressions and control structures.

    Readings:

    • Brush up on C basics (syntax, data types, operators, control structures) via your favorite C reference; sections 1-2 of Nick Parlante's EssentialC; or chapters 1, 2, and 3 of K&R. Skip content on I/O and standard libraries (we are bare metal!)
    • Read Dennis Ritchie's account of the history of C
    • Try out the Compiler Explorer demoed in lecture
    • Read our guides on make and gcc
    Lab/assign Lab 1: Getting to know your Mango Pi ( writeup )

    Please do the Lab 1 prelab preparation before coming to lab.

    		 Assignment 1: Larson Scanner
    Lecture
    Fri 4/10     		C Pointers and Arrays ( )

    Memory, addresses, and pointers. Address arithmetic, layout of arrays and structures. Typecast and volatile.

    Readings:

    • Review EssentialC chapters 3 and 6 (postpone heap and memory management for later) or K&R 5.1-5.4.
    • C volatile can be subtle and tricky. See GeeksForGeeks advice on correct use and John Regehr's blog on what NOT to do with volatile

    See schedule for entire quarter.
