Question 4

Consider two blocks,one within another.If an identifier is declared as a variable in the inmost of these two blocks,one can access this variable from the outer block.

Accepted Answer

A) True 
 B)False

Question 5

double totalCost(int numberParam,double priceParam);
with the more terse,alternate form
double totalCost(int,double);

Accepted Answer

A) True 
 B)False

Question 6

Calling something a black box is a figure of speech that conveys the idea that you cannot see inside.You know its behavior and interface but not its implementation.

Accepted Answer

A) True 
 B)False

Question 7

In your own words discuss similarities and differences between a function and a small program.

Accepted Answer

A function definition is like a small pr

Question 8

What do the calls to exit(…)do? When exit(0)and exit(1)are called,what receives these arguments and what is done with them?

Accepted Answer

A) The exit( )function stops the program.The argument is discarded. 
B) The exit( )function is obsolete.There is no longer any such function in the C++ libraries. 
C) The exit( )function stops the program.The argument is passed to the operating system which uses it for an error code. 
D) The exit( )function temporarily stops the program,and sends the argument to the operating system which uses it for an error code.The operating system restarts the program after fixing the error. 
E) The exit( )function allows the systems programmer to escape when the power supply catches fire.

Accepted Answer

A) Within the parameter list of a function definition 
B) Within the block of a void function. 
C) Within the argument list of a function call 
D) Within a block nested within another block 
E) Within the block of a value returning function.
