What 4 pieces of information do you need to declare an array?
|
Type, Name, Dimensions, and Size
|
|
|
What are the four types of arrays?
|
Single-Dimension, Jagged, Two-Dimensional, & Multi-Dimensional
|
|
|
This array is initialized at declaration time with explicit values.
|
Single Dimension Array ex: int[] myInts= {5, 10, 15 };
|
|
|
This is an array of arrays which consists of the primary array and sub arrays. This array will only allocate memory for the size of each array in each dimension that you define.
|
Jagged Array
|
|
|
In this array where each dimension is seperated by a comma and must also be instantiated by the "new" operator.
|
Two-Dimensional Array
|
|
|
This array will allocate memory for every element of each dimension.
|
Multi-Dimensional Array
|
|
|
A storage location for data. You can place data within them and retrieve their contents.
|
Variable
|
|
|
List the 5 simple types
|
Boolean, Integrals, floating point, decimal & string
|
|
|
List the 5 different integral types.
|
byte, short, int, long, char
|
|
|
When are floating point types used?
|
when you need to perform operations requiring fractional representations.
|
|
|
when are decimal types used?
|
when you need to perform financial calculations to avoid rounding errors.
|
|
|
How do you represent the verbatim literal in a string
|
with the @ symbol
|
|
|
What is the if statement
|
allows you to take different paths of logic, depending on a given condition.
|
|
|
What are the three types of if statements?
|
if, else if, & else
|
|
|
What is the difference between regular OR ( | ) and conditional OR ( || )
|
The boolean expression will evaluate to true if either of the two sub expressions on either side of the operator evaluate to true. The difference is the regular OR operator will evaluate both sub expressions every time. However the conditional OR will evaluate the second sub expression only if the firs expressions evaluates to false.
|
|
|
What type of values can a switch statement operate on
|
booleans, enums, integral types, and strings.
|
|
|
What are the four types of loops?
|
While, Do, for, foreach
|
|
|
This loop will check a condition and then continue to execute a block of code as long as the condition evaluates to a boolean value of true
|
The While loop
|
|
|
What is the difference between the Do and While loop?
|
the do loop check its condition at the end of the loop. This means that the do loop is guaranteed to execute at least one time. The while loop evaluates its expression at the beginning of the loop.
|
|
|
When are for loops appropriate?
|
When you know exactly how many times you wish to perform the statements within the loop.
|
|
|
These provide the opportunity to protect a field in a class by reading and writing to it through the property.
|
Properties
|
|
|
What is a struct?
|
