The size of the array shoeSize? double [] shoeSize = {8.5, 7, 12.5, 9.5, 9, 11.5, 6} is 6
Explanation:
- Arrays are zero-based : the seven elements of a 7-element array are numbered from 0 to 6. Hence, the size of the array is 6.
- An array is collection of items stored at memory locations. The main aim of an array is to store multiple items of same type together.
- An array is a collection of one or more values of the same type. Each value is called an element of the array.
- The location of an item in an array is known as array indexing.
- The first array index is 0 or 1 and indexes continue through the natural numbers.
- The upper bound of an array is generally language and possibly system specific.
- An array type is a data type that represents a collection of elements each selected by one or more identifying keys that can be computed at run time during program execution.
Answer:
Task 1: T = c + (2.5n(A/M))+ m(1+r/100)ⁿ
Task 2: In both 5 & 10 years, Car A is more economical
Task 3: Printing returns the answer in a different dialogue box while return displays the answer in the same window.
Explanation:
Task 1:
C = Cost of car
n = Number of years
m = Maintenance Cost
r = Rate
M = Mileage per gallon
A = Annual mileage
T= Total Cost
T = c + (2.5n(A/M))+ m(1+r/100)ⁿ
Task 2
Car A In 5 years; T = 20000+ (2.5*5(15000/25))+1300(1+0.15)⁵= $30115
Car B In 5 years; T = 30000+ (2.5*5(15000/32))+1000(1+0.10)⁵= $37470
Therefore in 5 years, Car A is more economical.
Car A In 10 years; T = 20000+ (2.5*10(15000/25))+1300(1+0.15)¹⁰= $40259.225
Car B In 10 years; T = 30000+ (2.5*10(15000/32))+1000(1+0.10)¹⁰= $ 44312.49
Therefore in 10 years, Car A is still economical.
Task 3: Printing returns the answer in a different dialogue box while return displays the answer in the same window.
Answer:
The answer to the given question is the option "c".
Explanation:
In this question, the answer is "common transport". It is the layer responsible for end-to-end interaction that is used on the HTTP and FTP. This layer provides a logical interaction between applications that are run on different hosts within a layered protocol structure and other options are not correct that can be described as:
- In option a, The cable stands for wire that is not a part of the layer.
- In option b, An application uses the common transport for interaction. that's why it is not correct.
- In option d, Physical is a part of the OSI model and it is used for bit-level transmission that's why it is not correct.
So the answer to this question is the option "C".

Answer:
Option C, ENCRYPTING FILE SYSTEM (EFS).
Explanation:
Encryption is one of the best protection methods available to keep all one's digital assets safe.
Encrypting file system (EFS) is a feature of windows 2000 operating system that allows any file or folder be stored in an encrypted form and decrypted only by an individual user and an authorized recovery agent.
EFS provides filesystem-level encryption. This technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer.
To encrypt or a file using EFS;
Open windows explorer
Right-click the file or folder and select properties
Click advanced in the general tab
Check encrypt contents to secure data
Click ok.
Therefore, option C, ENCRYPTING FILE SYSTEM, is an encryption tool that allows users to encrypt files and folders by simply right-clicking a given object and setting a few options.
