Module 8: Arrays

It is basically, a variable that can store multiple values with the same data type.

• List

• Array

• Object

• Int

Arrays best work with..

• if else

• while loop

• do-while loop

• for loop

The correct syntax of declaring an array is?

• dataType arrayName [arraySize];

• dataType arrayName = [arraySize];

• dataType arrayName [ ];

• arrayName dataType [arraySize];

The correct syntax of assigning values upon declaration/ intitialization is?

• dataType arrayName [arraySize] = { value1, value2, value3 };

• dataType arrayName = [arraySize] { value1, value2, value3 };

• dataType arrayName [ ] = { value1, value2, value3 };

• arrayName dataType { value1, value2, value3 } [arraySize];

In an array with a size of 10, what is the first index?

• 0

• 1

• 9

• 10

Given the array

int list [ ] = { 1, 2, 3, 4 };

what is the value of list [ 0 ]

• 1

• 4

• 2

• 0

In initializing or assigning values upon declaration in multi-dimensional array, arraySize is optional.

• True

• False

• Cannot be determined.

The syntax for declaring a multi-dimensional array is...

• dataType arrayName [arraySize1] [arraySize2] ... [ arraySizeN];

• dataType arrayName [ ] [ ] ... [ ];

• arrayName dataType [arraySize1] [arraySize2] ... [ arraySizeN];

• dataType arrayName = [arraySize1] [arraySize2] ... [ arraySizeN];

The syntax for initializing values in a multi-dimensional array or assigning values upon declaration is...

• dataType arrayName [arraySize1] [arraySize2] ... [ arraySizeN] = { { <list of values> }, { <list of values> }};

• dataType arrayName [ ] [ ] ... [ ] = { { <list of values> }, { <list of values> }};

• arrayName dataType [arraySize1] [arraySize2] ... [ arraySizeN] = { { <list of values> }, { <list of values> }};

• dataType arrayName = [arraySize1] [arraySize2] ... [ arraySizeN] { { <list of values> }, { <list of values> }};;

Given the program:

int num[2][2] = { { 4, 5 }, { 4, 4}, { 5, 3} };

what is the value of num[2][2];

• 4

• 5

• 3

• error
