Question

Provide the definition for each of the following structures and

unions:
a) Structure inventory containing character array
partName[ 30 ], integer partNumber,
floating point price, integer stock and integer reorder.
b) Union data containing char c, short s, long b, float f
and double d.
c) Structure test containing 16 bit fields with widths of
1 bit. The names of the bit fields
are the letters a to p.

Answer 1

The structure 'inventory' includes character, integer, and floating-point types to represent part information, whereas the union 'data' can hold one of several different types in the same memory location.

Step-by-step explanation:

A structure in programming defines a composite data type that groups variables under a single name. For example, a structure named inventory may contain the following members: a character array partName[ 30 ] for storing the name of the part, an integer partNumber for the part's unique number, a floating-point number price denoting the cost of the part, an integer stock indicating the quantity currently on hand, and an integer reorder level which is the stock level that triggers reordering.

A union in programming is a data type that allows storage of different data types in the same memory location. For the union named data, it can contain either a character c, a short integer s, a long integer b, a floating-point number f, or a double-precision floating-point number d, but only one of these at a time.

Lastly, a structure named test can define 16 bit fields, each one bit wide, named from a to p. Bit fields allow more efficient use of memory when you know the size of the data is small.
