Exam 7: User-Defined Simple Data Types, Namespaces, and the string Type

Suppose that str1,str2,and str3 are string variables.After the following statements execute,the value of str3 is "____". str1 = "abc"; Str2 = "xyz"; Str3 = str1 + '-' + str2;

Consider the following statements: string str1 = "Gone with the wind"; String str2; After the statement str2 = str1.substr(5,4); executes,the value of str2 is "____".

In C++,____ is a reserved word.

A function cannot return the value of an enumeration type.

The following is a legal C++ enumeration type: enum colorType {BLUE,GREEN,PINK,YELLOW,RED};

If a global identifier in a program has the same name as one of the global identifiers in the header file,the compiler generates a(n)____________________ error.

For the operator + to work with the string data type,one of the operands of + must be a(n)____________________ variable.

The identifiers in the system-provided header files such as iostream,cmath,and iomanip are defined in the namespace ____.

The following is a valid C++ enumeration type: enum places {1ST,2ND,3RD,4TH};.

Which of the following statements creates an anonymous type?

An enumeration type can be passed as a parameter to a function only by value.

Which of the following statements is used to simplify the accessing of all globalType namespace members?

The following statement creates an anonymous type: enum {1ST,2ND,3RD,4TH} places;

Suppose that you have the following declaration. enum cars {FORD,GM,TOYOTA,HONDA}; Cars domesticCars = FORD; The statement: DomesticCars = static_cast<cars>(domesticCars + 1); Sets the value of domesticCars to ____.

The length of the string "Hello There." is ____.

In July ____,ANSI/ISO Standard C++ was officially approved.

The data type string has a named constant,____________________,associated with it.

The string expression strVar.____________________ starts at index pos,replaces the next n characters of strVar with all the characters of str.

What is the output of the following code? enum courses {ALGEBRA,BASIC,PASCAL,PHILOSOPHY,ANALYSIS}; Courses registered; Registered = ALGEBRA; Cout << registered << endl;

In C++,namespace is a reserved word.
