Four basic data types
Character integer float boolean
//
/*
*/
Comments - compiler ignores everything after the comment until the end of the line.
Single line comment
Start multiple line comment
Stop multiple line comment
Four essential Loop actions
I
C
C
B
Initialization: assigns initial value
Condition: evaluate the control variable to determine whether the loop should execute or not
Change: changes the value of the control variable to ensure the loop as a means to exit.
Body: statements defined between the opening and closing curly braces of the for Loop.
If
Else if
Else
Are all what?
If statements
!
&&
| |
These are what kind of statements and what are their names.
Decision statements
Not
And
Or
What is a constant?
A named memory location whose value cannot change
What is a variable
A named memory location
What are the four program structural components?
D
I
P
O
Declarations: storage for data being workedwith.
Input: allows acquisition of data from a source.
Processing: manipulating data to arrive at a result.
Output: provides processed data to find a destination. Could be a monitor a file on the hard drive or a web page

What is this symbol called?
flow line
It shows the direction of program flow on a flowchart.
What is the flowchart symbol for a predefined process?
The symbol should be a rectangle with two thin vertical rectangles on either side.
What is the flowchart symbol for decision?
The symbol is a daimond it represents Branch based boolean decision making. Has a true or false output.
What is the flowchart symbol for input/output?
It should look like a parallelogram and represents input from user or output to a display.
What is the flowchart symbol for terminal?
Terminal is represented by an oval and represents a programs start or stop point.
What is the flowchart symbol for process?
The symbol is a rectangle and it represents an action to be executed.
int my number = 0;
Is a?
Integer
float myNumber = 0.0;
Is a?
Float
char meLetter = ‘A’
Is a?
Character
bool mybool = true;
Is a?
Boolean variable
Two terms associated with strings?
Index and element
What does concatenation do?
Ex below
std: :String str1 = “you got “;
std: :String str2 =”that right”;
std: :String str3 = str1+” “+str2;
It’s the process of joining two strings.
Name the symbols and the group they belong to. \n \t \0 \" \\
Group is escape characters. New line Tab Null if it's inside a string Double quote if inside a string Single slash back inside a string
What type and what do they represent?
STDOUT
STDERR
STDIN
They are input/output types
STDOUT- OUTPUT TO A MONITOR
STDERR-STANDARD ERROR
STDIN-STANDARD INPUT
What is
COUT
Output to display
What is
CERR
Displays error messages on the screen.
What is
CIN
Input, program received information.
What does,
std::cin
do?
Reed’s numbers single line characters and strings of letters stops at White spaces if multiple lines are typed
What does get line() Do?
Reads all data including white spaces.
What is
ws()
used for?
It’s placed on the line previous to getline() when using a program that mixes both getline() and cin when receiving an input. Reads white spaces.
