Topical Information

This test will cover the blank and welcome/hello programs — that is, the basic structure of all C++ programs including standard library usage, cout and displaying things on the screen, the twelve built-in data types and declaring variables and constants of those types, cin and basic input techniques and properties, and building a program from scratch.

In more detail, we've talked about:

• background:
  • computer parts: CPU, RAM, disk, monitor, keyboard
  • languages: machine, assembly, procedural, object-oriented, symbolic, functional
  • programming process: high-level language --> compiler --> executable
  • errors: syntax vs. logic
• C++ basics:
  • main, iostream, #include, return, ;
  • console, cout, <<, "string", '\t', '\n', cin, >>
  • data types: short, long, (int), double, char, bool, etc.
  • arithmetic: (), -, *, /, +, -, =
  • literals vs. constants vs. variables
  • importance of order:
    • edit [create/change], save, compile, run
    • declare, read, calculate, print
  • style: comments (//...\n as well as /*...*/), naming (A-Z, a-z, 0-9, _; not too short, but not too long), indention ({}!; tabs vs. spaces), other spacing (in code vs. on screen; blank lines, operator spacing, etc.)
• standard library:
  • libraries:
    • iostream: cout, cin, <<, >>

Bonus Information

Possible bonus questions from above or the following:

• more arithmetic:
  • integer division
  • modulo (%):
    • unit conversion
    • digit [group] extraction
    • random number generation
  • type casting (static_cast<desired type>(expression))
• more standard libraries:
  • ctime:
    • time(nullptr)
  • cmath:
    • floor(x)
    • ceil(x)
    • fabs(x)
    • sqrt(x)
    • pow(base, exponent)
    • exp(x)
    • log(x)
    • log10(x)
    • sin(r)
    • cos(r)
    • tan(r)
    • asin(t)
    • acos(t)
    • atan(t)
    • atan2(y, x)
  • cstdlib:
    • srand(seed)
    • rand()
    • RAND_MAX
    • abs(n)
    • labs(n)
  • limits:
    • numeric_limits<streamsize>::max()
  • more iostream:
    • using the dot (.) operator with cin to call its class functions
    • ignore:
      • no arguments
      • two arguments: count and terminating character
      • ...and when the count is numeric_limits<streamsize>::max()...
• object oriented basics:
  • a class describes a group of things' general characteristics
  • a class is a data type
  • variables of a class type are called instances or objects
  • cin is an object of a class
  • cout is an object of a class
  • in particular a class describes behaviors or actions a groups' members may be involved with as functions
  • such member functions (aka methods) are called via the dot (.) operator
  • dot operator syntax to call a member function with respect to a class object is: object.function(arguments)

Temporal Information

The first test will be Thursday of week 3 — September 6^th during the last 45 minutes of lecture.
