to prevent changes to the structure members
A good reason to pass a structure as a constant reference is ________.
variables
C++ allows you to group several _______ into a structure
abstract data types (ADT)
Data types that are created by the programmer are known as ________.
takes a Circle structure as a parameter, does something, and returns a Circle structure
If Circle is a structure tag, the statement: Circle doSomething(Circle c2) can be the header line for a function that ________.
Output the dereferenced value pointed to by p.
If a is a structure variable and p, a pointer, is a member of the structure, what will the following statement do? cout << *a.p;
strongly typed enum
In C++ 11 you can use a new type of enum, known as a(n) ________, (also known as an enum class) to have multiple enumerators with the same name, within the same scope.
null character
In C++, a C-string is a sequence of characters stored in consecutive memory, terminated by a ________.
false
Look at the following declaration. enum Tree { OAK, MAPLE, PINE }; What is the value of the following relational expression? OAK > PINE
¿¿ both a & c ??
Look at the following statement. if (!isdigit(var1)) The expression being tested by this statement will evaluate to true if var1 is:
anonymous
Members of a(n) ________ union have names, but the union itself has no name.
guarantees not to result in changes to the structure's members
Passing a structure as a constant reference parameter to a function ________
data type
The name of the structure is referred to as its ________.
::
The symbol for the scope resolution operator is _____ .
abstraction
This describes only the general characteristics of an object.
atoi
This function accepts a C-string containing a number as its argument and returns the integer equivalent.
strlen
This function accepts a pointer to a C-string as an argument, and it returns the length of the C-string (not including the null terminator).
strcat
This function concatenates the contents of one C-string with another C-string.
atoi
This function converts a C-string to an integer and returns the integer value.
union
This is like a structure, except all members occupy the same memory area
toupper
To change a character argument from lower to upper case, use this function.
char lastName[26];
To define a C-string that will store students' last names of up to 25 characters in length, which is an appropriate statement?
the structure pointer operator, ->
To dereference a structure pointer, the appropriate operator is ________.
isalpha
To determine whether a character entered is a letter of the alphabet, use this function.
isspace
To determine whether a character is whitespace, use this function.
isprint
To test whether a character is a printable character, use this function.
