MULTIPLE CHOICE QUESTION

Chapter:12 (Larger Programs)

Question 1:

One advantage of separate compilation of program modules is

the resulting program will be more modular compilation time can be faster program modules can be protected from inadvertent alteration during program development all of the above

Question 2:

Separately compiled modules are combined using the

Linker Compiler Both a and b None of the above

Question 3:

For a variable to be visible in a file other than that where it was defined, it must be ____

Initialized Declared Both a and b None of the above

Question 4:

For a variable to be visible in a file other than that where it was defined, it must be declared using the keyword ________

printf int *ptr Exam None of the above

Question 5:

Which of the following are ways to pass information from one function to another function in a separately compiled file?

as arguments as static variables as external variables a and c

Question 6:

Separate compilation is an aid to modular programming because

functions cannot access variables in other files only functions relating to the same program can be combined in one file external variables can be restricted to one file None of the above

Question 7:

Conditional compilation is used to

compile only those programs that are error free compile some sections of programs and not others remove comments and compress the source file none of the above

Question 8:

The ___________ preprocessor directive is used as a switch to turn compilation on and off.

#class #delcare #define None of the above

Question 9:

The preprocessor directive #if define (ADV) causes the code that follows it to be compiled only when

ADV is an integer ADV is equal to a predefined constant ADV is TRUE ADV is #defined

Question 10:

Using different memory models is useful when a program or data becomes too ________

Large Small both a and b none of the above

Question 11:

The medium memory model permits

more than one code segment only one data segment only one code segment a and b

Question 12:

Memory models are necessary because of the __________

stack-based architecture of the microprocessor segmentation of memory need to keep programmers guessing b and c

Question 13:

The disadvantage of using a memory model that is larger than necessary is

memory is wasted simple data type cannot be used program files are harder to link program instructions take longer to execute

Question 14:

Which of the following process are used to make an executable file ?

Linking Compile Code written All of the above

Question 15:

____________ which calculated the sum of the squares of two numbers.

multifun.h multifun.c multifun.exe multifun.obj

Question 16:

You can have ___________ files open at the same time in the IDE, in separate windows

Must be more than two Only one Two or more All of the above

Question 17:

When a variable is _____________ , it is given a data type (int or whatever) and a name.

Defined Declared Both a and b None of the above

Question 18:

_______________ an external variable is visible in the file in which it’s defined, from the point of the definition onward.

String Memory Function None of the above

Question 19:

_________________ allow the compiler to produce differences in the executable produced controlled by parameters.

Compilation Conditional compilation Decision compilation Both b and c

Question 20:

The ___________ TIMER directive tells the compiler to compile the statements that follow it only if TIMER is #defined.

#fprintf() #fwrite #ifdef #fndef
