You need to ensure that the debugger breaks execution within the CalculateInterest() method when the loanAmount variable is less than or equal to zero in all builds of the application.
What should you do?
A. Insert the following code segment at line 03: Trace.Assert(loanAmount > 0);
B. Insert the following code segment at line 03: Debug.Assert(loanAmount > 0);
C. Insert the following code segment at line 05: Debug.Write(loanAmount > 0);
D. Insert the following code segment at line 05: Trace.Write(loanAmount > 0);
Answer: A
Explanation:
By default, the Debug.Assert method works only in debug builds. Use the Trace.Assert method if you want to do assertions in release builds. For more information, see Assertions in Managed Code. http://msdn.microsoft.com/en-us/library/kssw4w7z.aspx
Q9. - (Topic 1)
You are creating an application that manages information about your company's products. The application includes a class named Product and a method named Save.
The Save() method must be strongly typed. It must allow only types inherited from the Product class that use a constructor that accepts no parameters.
You need to implement the Save() method. Which code segment should you use?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: D
Explanation:
When you define a generic class, you can apply restrictions to the kinds of types that client
code can use for type arguments when it instantiates your class. If client code tries to instantiate your class by using a type that is not allowed by a constraint, the result is a compile-time error. These restrictions are called constraints. Constraints are specified by using the where contextual keyword. http://msdn.microsoft.com/en-us/library/d5x73970.aspx
