Topical Information

Since the last exam, we've talked about:

• 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)

And any of that could be on this exam in the credit section.

Bonus Information

Possible bonus questions may come from the above topics or from the following topics:

• cctype: is___ and to___er functions
• if and else for simple decision making
• factoring code from a branch structure
• ==, !=, <, etc. for comparing values
• &&, ¦¦, ! for manipulating logical values
• DeMorgan's Laws for negating logical combinations
• while for simple repetition
• the accumulation loop pattern (including counting)
• domain validation loop pattern
• peek for detecting input before it is processed
• fail/clear for detecting numeric input failure and correcting it

Temporal Information

The second test will be Tuesday of week 5 — September 18^th during the last 45 minutes of lecture.
