COIT11133, Lecture 24
- Revision
2
Overview
- What did you learn
- statements
- expressions
- variables and types
- I/O
- design
- functions
- skills
- Study suggestions
3
Statements
switch/for
4
Examples
- What is the output from the following C
program? - include
- using namespace std
- void main()
- int score 2
- for (int i 0 i
- score 3
- cout
5
Examples
- Write a program to display the following pattern.
Your program should use at least one for loop. - 1 2 3 4
- 5 6 7 8
- 9 10 11 12
6
Variables and Types
- declaration and initialisation
- valid operations
- int double float char string
- Arrays
- subscripts and elements
- manipulating arrays
7
Examples
- The syntax of the following declaration and
initialisation is incorrect. Rewrite the
statement with the correct syntax. - char Initial A
8
Expressions
- Operators
- arithmetic
- relational
- boolean
- Expression evaluation
9
Examples
- Simplify the following logical expression
- !((Val 99) (Val
- Add parentheses to the following expression to
demonstrate explicitly the order in which the
mathematical operations are performed - 1 / 3 7 4 3
10
Advanced I/O
- Problems with cin and input of various types
- Formatting output
- I/O Manipulators
11
Example
- Given the definition
- string PlayerNameWrite a C statement to
accept input, possibly including blanks, from the
keyboard into the string PlayerName
12
Functions
- What is a function?
- Parameter passing
- by value (copy)
- by reference
- Return values/types
13
Example
- Write the definition for a function
CapitalFirst(). CapitalFirst() accepts one
string parameter by value and returns a string
return value. CapitalFirst() returns a string
that has the first letter of every word in
capital case and every other letter, lower case.
Thus if the string cENTRAL qUeenSLand
UNIversity was passed to CapitalFirst() it
would return the string Central Queensland
University
14
Structured Design
- Why top-down design?
- Structure charts
- How to design structured programs
15
Example
- A golfer wants to buy a golf club that is between
220 and 240 grams in weight. The golfer will
keep inspecting the available golf clubs until a
club of the correct weight is selected. Write a
C program to model this process. Your program
should ask the customer to enter the weight of
the current club, report That club is too heavy
if the club weighs more than 240grams or That
club is too light if the club weighs less than
220 grams. If a club weighs between 220 and 240
grams, the program should report This club is
the correct weight. The program should loop
until a correct club is obtained. It should then
terminate.
