Question 1

All of the following are reasons to use recursion except:

Accepted Answer

A)  An iterative solution is not apparent. 
B)  The resulting program is easier to debug. 
C)  It more naturally mirrors the problem. 
D)  It maximizes execution performance.

D)  It maximizes execution performance.

Question 2

[C++11]-Which of the following statements is false?

Accepted Answer

A)  An enumeration's constants have integer values. 
B)  An unscoped enum's underlying type is independent of its constants' values but is guaranteed to be large enough to store those values. 
C)  A scoped enum's underlying integral type is int, but you can specify a different type by following the type name with a colon (:) and the integral type. For example, we can specify that the constants in the enum class Status should have type unsigned int, as in enum class Status : unsigned int {CONTINUE, WON, LOST}; 
D)  A compilation error occurs if an enum constant's value is outside the range that can be represented by the enum's underlying type.

C)  Local variables it has declared. 
D)  The name of the function.

Accepted Answer

A)  To access a global variable when a local variable of the same name is in scope. 
B)  To access any variable in an outer block when a local variable of the same name is in scope. 
C)  To access a global variable when it is out of scope. 
D)  To access a local variable with the same name as a global variable. 
A)  To access a global variable when a local variable of the same name is in scope. 
B)  To access any variable in an outer block when a local variable of the same name is in scope. 
C)  To access a global variable when it is out of scope.

B)  Defines a function called double which calculates square roots. 
C)  Defines a function called mySqrt which takes an argument of type x and returns a double. 
D)  Declares a function called mySqrt which takes a double as an argument and returns an integer.

Question 7

What happens when two blocks, one nested inside of the other, both declare variables with the same identifier? (Assume that the outer block declares its variable before the opening left-brace of the inner block.)

Accepted Answer

A)  A syntax error occurs. 
B)  The "outer" variable is hidden while the "inner" variable is in scope. 
C)  The "outer" variable is irretrievably lost when the "inner" variable is declared. 
D)  The "inner" declaration is ignored and the "outer" variable has scope even inside the inner block.

B)  They must be the rightmost (trailing) arguments in a function's parameter list. 
C)  Default values can be constants. 
D)  Default values cannot be global variables or function calls.
