CNIT 315 EXAM 2 QUESTIONS & ANSWERS

Data field - Answers -data items that are entities themselves (ex. Name: __________)

Record - Answers -all data fields form a single field called this

Structure - Answers -In C a record is referred to as this

Structure's form - Answers -consists of the symbolic names, data types, and
arrangement of individual data fields in the record

Structure's contents - Answers -consist of the actual data stored in the symbolic names

Single Structure layout - Answers -struct
{
int month;
int day;
int year;
} birth;

Single Structure definition - Answers -Reserves storage for the individual data items
listed in the structure

Members of the structure - Answers -data items declared in the struct (ex. int month;)

Populating the structure - Answers -Assigning actual data values to the data items of a
structure

Rigid - Answers -Spacing of a structure is not ________

Structure type name - Answers -defined by user and first letter is capital (ex. struct
Date)

Arrays - Answers -Initialization of structures follows the same rules as for the
initialization of ___________

True - Answers -Structure members can be of any data type

struct
{
char name[20];
struct Date birth;
} person;

, Valid: person.name[4]; - Answers -Individual members can be arrays and structures,
advantage that same structure type can be used in a list many times

NUMRECS 5 - Answers -Used to define an array of data

0/nulls - Answers -Without explicit initializers, the numeric elements of both static and
external arrays or structures are initialized to ______________

Parallel arrays - Answers -are two or more arrays, where each array has the same
number of elements and the elements in each array are directly related by their position
in the arrays, rarely used anymore

display(emp.idNum) ;
calcPay(emp.payRate,emp.hours); - Answers -Individual structure members may be
passed to a function in the same manner as any scalar variable

calcPay(emp); - Answers -On most compilers, complete copies of all members of a
structure can also be passed to a function by including the name of the structure as an
argument to the called function

Reference - Answers -A structure can be passed by this ( ex. calcNet(&emp);
double calcNet(struct Employee *pt)
(*pt).idNum or *pt->idNum )

++ and -- - Answers -can be applied to structures (ex. ++pt->hours
(pt++)->hours
(++pt)->hours )

Union definiton - Answers -is a data type that reserves the same area in memory for
two or more variables, only one at a time though, reserves sufficient memory locations
to accommodate its largest member's data type

Union layout - Answers -union
{
char key;
int num;
double price;
} val;

struct
{
char uType;
union
{
char *text;
double rate;
