105 Topics, Midterm 1 concept of an "operating system" compilation editor shell parts of the computer (computer organization) 4 kinds of memory pre-processor directives resources in computer science six stages of a C program expressions statements data types variables (and memory) assignment statements math operators recognize function calls logical operators, and operator precedence constants truth values, boolean expressions, logical operators conditionals (if, if/else, switch, ) printf, scanf, format control statements, format specifiers iteration definite iteration (for loops, while loops) indefinite iteration (while loops, sentinel loops) nested loops pre-defined function libraries, including stdio.h binary, hex, octal, decimal number systems shell commands: cp, mv, rm, ls, cat, mkdir directories structured programming (sequence, selection, and repetition) finding min, max, count, sum, average of a sequence of data values return value from main program ************************************************************ future topics: arrays structs pass-by-reference vs. pass-by-value addresses pointers functions write function prototypes write function definitions distinguish betweeen function prototype, definition and call. distinguish between actual and formal parameters/arguments ternary operator indefinite iteration (do while) recursion malloc and free file I/O pre-defined function libraries, including math.h C-strings, and string functions DeMorgan's law functional decomposition dereferencing operators pointer expressions shell commands: cp, mv, rm, chmod, ls, cat, more basic html and chmod to create simple web pages directories compiler commands command line arguments scope linear search binary search sorting: either selection or insertion sort finding min, max, count, sum, average of a sequence of data values (from either an input file or an array). menu driven programs return value from main program, and relation to shell scripts. linked lists optional (covered in CISC181)
