B)  calls itself 
C)  has no return type 
D)  None of the above 
A)  calls another method 
B)  calls itself 
C)  has no return type 
D)  None of the above

Question 3

Methods should be large and perform as many tasks as possible.

Accepted Answer

A) True 
 B)False

Question 4

Accepted Answer

A) True 
 B)False

Question 5

Consider the following Cube method:
Static int Cube(int x)
{
Return x * x * x;
}
Which of the following statements is false

Accepted Answer

A)  In C# 6, this method can be defined with an expression-bodied method as
Static int Cube(int x) = > x * x * x;
The value of x * x * x is returned to Cube's caller implicitly. 
B)  The symbol = > follows the method's parameter list and introduces the method's body-no braces or return statement are required. This can be used only with static methods. 
C)  If the expression to the right of = > does not have a value (e.g., a call to a method that returns void), the expression-bodied method must return void. 
D)  Similarly, a read-only property can be implemented as an expression-bodied property. The following re-implements the IsNoFaultState property we used in the textbook to return the result of a logical expression:
Public bool IsNoFaultState = >
State == "MA" || State == "NJ" || State == "NY" || State == "PA";

B)  recursion step(s) 
C)  base case(s) 
D)  None of the above.

Question 8

Methods of the same name can be declared in the same class,as long as they have different sets of parameters (determined by the number,types and order of the parameters).

Accepted Answer

A) True 
 B)False

Question 9

If a local variable in a method has the same name as a field of the method's class,what will occur

Accepted Answer

A) an error is generated 
B)  the field is "hidden" until the method is finished executing 
C)  the field will override the variable from the method 
D)  None of the above. 
A) an error is generated 
B)  the field is "hidden" until the method is finished executing 
C)  the field will override the variable from the method 
D)  None of the above.
