A) Fixed (F)
B) Number (N)
C) General (G)
D) Currency (C)

Accepted Answer

The Fixed (F) format specifier displays a number with a fixed number of decimal places. By default, it displays two decimal places, but it can be altered by adding a number after the F. Therefore, using ToString("F2") on the value 8976.43561 will display it as 8976.44.

Question 10

The process of joining two string values together is called ____.
A) addition
B) alignment
C) combination

An Overflow exception occurs when a calculation creates a value larger than one that can be processed by a procedure. This typically happens when the result of a calculation is too large to be stored in a specific data type, such as an integer or a floating-point number. The value "overflows" the data type's limit and can cause unexpected behavior in the program if it is not handled properly.

Question 17

When the user interacts with an object in the graphical user interface, the ____ shifts to that object.
A) scope
B) focus
C) visibility
D) precision
