Midterm Exam
Review - Fall 2008
Material covered: Savitch, Chapters 1-4
Introduction to Computers and C++ Programming
Know the basic principles of computers and computing, including
hardware (i/o, memory, CPU) and software (machine, assembly, and
high-level languages, compilers, operating systems).
Chapter 1 - C++ Basics
Know the basic components of a C++ program:
header files (e.g., #include<iostream>)
main() function
I/O (cin and cout objects)
// comment statements
variables
assignment statement
data types
arithmetic operators
formatting output with stream functions: precision()
and
setf() with flags ios::showpoint, ios::fixed and ios::scientific.
formatting output with the stream manipulator setw().
Be able to define the following terms relating to representation of
numbers in a computer:
Precision (the number of digits in the mantissa of a
floating
point number)
Range
Exponent
Roundoff and relative errors
Underflow and overflow errors
Chapter 2 - Flow of Control
Know how to build boolean expressions using relational operators
(<, ==, <=, etc.) and logical operators (&&, ||, !).
Know how and when to use the following control structures:
Branching structures - if
and if-else statements, switch statement
Looping structures - while, do-while, and for loops
Be able to define the following terms:
Pre- and post-test loops
Fixed count loops (counter controlled repetition)
Sentinel controlled loops
Chapters 3 & 4 - Functions
You will be asked to write a function to do some task. You
will
have to provide the function's declaration, header, definition
(header + body), and call.
Know the difference between parameters and arguments and their
relationship. Know what it means to call-by-value and to call-by-reference
using reference parameters. Know how to use the return
statement to pass a value back to the calling program.
You should be able to define (and use, if appropriate) the following
terms: global variable, local variable, scope.
Finally:
Be able to write a complete C++ program that includes these
components.
There will not be any
questions about: random numbers, Trapezoidal Rule, Newton-Raphson
method, recursive functions.
