Question
True/FalseIndicate whether the sentence or statement is true or false.
____ 50. An array is not a structured data type.
____ 51. Creating an array of ten integers named employee requires the declaration int employee[10];
____ 52. The setiosflags(ios::left) manipulator included in the cout object stream forces each name to be displayed left-justified in its designated field width.
____ 53. Individual structure members cannot be passed to a function as arguments.
____ 54. The statement display(emp.idNum); passes a copy of the structure member emp.idNum to a function named display().
____ 55. The starting address of a structure is the address of the first member of the structure.
____ 56. The increment and decrement operators cannot be applied to pointers.
____ 57. A class defines both data and functions.
____ 58. Although the initial capital letter is not required, it is conventionally used to designate a class.
____ 59. The standard syntax for referring to an object’s attribute is: objectName.attributeName.
____ 60. All class functions should be public.
____ 61. Default values cannot be used in a constructor function.
____ 62. A “pure” object-oriented language must always use classes.
____ 63. Instantiation is the process of renaming an object.
____ 64. Other names for operations defined in a class implementation section are procedures, functions, services and methods.
____ 65. Every constructor must be declared with no return type (not even void).
____ 66. In an object-oriented environment, as long as the existing outside interface is maintained, the internal implementation of any and all operations can be changed without the user ever being aware that a change took place.
____ 67. A file is a collection of data that is stored together under a common name.
____ 68. A file is physically stored on an external medium such as a disk.
____ 69. Very long file names should be avoided because they take more time to type and can result in typing errors.
____ 70. Each file stream has its own mode, which determines the direction of data on the transmission path—that is, whether the path will move data from a file into a program or whether the path will move data from a program to a file.
____ 71. Using the DOS convention, the first eight characters of a file name describe the data, and an extension (the characters after the period) describes the application.
____ 72. File stream objects must be explicitly declared.
____ 73. The declaration ifstream inFile; declares an input file stream object named infile to be an object of the class ifstream.
____ 74. Stream object names, such as inFile and outFile are not programmer-selected.
____ 75. In using the open() method to connect the file’s external name to its internal object stream name, only one argument is required, which is the external file name.
____ 76. One of the problems associated with embedding a file name within program code is that there is no provision for a user to enter or change the desired file name while the program is executing.
____ 77. The close() method does not break the connection between a file’s external name and the file stream object.
____ 78. The open() call is a request to the operating system that can fail for a variety of reasons.
____ 79. Multiple files can be open at the same time.
