Midterm Exam
1
Review - Spring 2009
Material covered: Savitch, Chapters 1 and 2
Here are some sample exam
questions.
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) components, and the
stages of problem solving.
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 to use the following control structures:
Branching structures - if, if-else, and switch statements
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
Finally:
Be able to write a complete C++ program that includes these
components.
There will be some definitions on the exam - these can appear
in
TRUE/FALSE or "match-the-term" questions or will have to be explicitly
written
by you.
