Explanation:

See attachment for right presentation of question

Analyzing the options:

(a): May return a negative result

This option will return a negative value if marker1 is less than marker2 because it subtracts the absolute value of marker2 from the absolute value marker1.

This literally is not different from marker1 - marker2

(b): Incorrect expression

This divides only marker2 by 60, then subtracts the quotient from marker1. This is not the expected expression.

(c) This option is correct

This correctly calculate the positive difference between marker1 and marker2 and the result is divided by 60.0 (note 60.0 not 60)

(d) & (e) Integer division

When a variable declared as double is divided by an integer variable or value, the result of the computation is not always accurate due to approximation

Character positions in arrays start counting with the number 1. True False

d1i1m1o1n [39]

Answer:

False.

Explanation:

A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.

In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.

This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.

In Computer programming, an array can be defined as data structure which comprises of a fixed-size collection of variables each typically holding a piece of data and belonging to the same data type such as strings or integers.

This ultimately implies that, when a programmer wishes to store a group of related data (elements) of the same type, he or she should use an array.

Generally, character positions in arrays start counting with the number 0 not 1.

Hence, an array uses a zero-based indexing and as such the numbering or position of the characters (elements) starts from number 0. Thus, the first character (element) in an array occupies position zero (0), the second number one (1), the third number two (2) and so on.
