1. Which of the following statements best describes "arrays"?
a. These are data types that can accommodate more than one data.
b. Set of clearly defined rules that are applied in order to solve problems.
c. These are data structure that can store more than one data of the same type.
d. The process of coding a program using a specific programming language.
1. Arrays are data structures that contains more than one data of the same type.
2. The first element in an array is found at index 1.
2. Using the declaration given below:
int x[] = {12, 13, 14, 15, 16, 17, 18, 19 };
What does x[2] refer to?
a. 12
3. Sometimes an index is called a subscript.
|ь. 14
С. 13
|d. 15
4. Consider the code below:
3. Using the code below:
int[] num= {2, 3, 4, 5};
Console. WritelLine(num[4]);
An IndexOutOfBounds exception is thrown during run time or execution of the program.
int[] myArray = {2, 4, 6, 8, 10, 1, 3, 5, 7, 9};
Console. Writeline(myArray,Length);
What is the value of 'Length' property of the array?
а. 10 b. 9 с. 11 d. 8
5. The last element in an array is accesses at length – 1.
4. How do you access an array element?
a. variable = i.name; c. variable = name.get():
b. variable = name.retrieve(i);
6. Array declaration is done through the syntax below:
|d. variable = name[i];
type[] arrayname = new type[length];
5. An array is a list of data items that:
7. Consider the code below:
int[] scores = {50, 70, 35, 80, 75, 90, 100, 95};
The value of Length property of the array score is 9.
a. have the same type
b. are all integers
c. have different names
d. are originally set to null ('\0')
6. For which of the following applications is an array NOT suitable:
8. Parameters are the variables passed on a method call.
9. Array elements can be identified using its subscripts.
a. Holding the scores on twelve midterm exams of a class.
b. Holding the name, social security number, age, and income of one individual.
C. Holding the temperature readings taken every hour throughout a day.
d. Holding the total sales a store made in each of twelve months.
10. Argument are the variables that receives the value(s) of the variables being
passed to a method
7. Based on the code fragment below, which of the statements would be placed on
the blank so that each item of the array is assigned twice the value of its index.
int array[10];
int index;
for (index=0;index<10;index++)
