What will be an ideal response?
Answer the following statements true (T) or false (F)
1. 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. 2. Consider two blocks, one within another. C++ prohibits an identifier to be declared as a variable in each of these blocks. 3. 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. 4. When a loop is nested in side another loop, a break or continue statement terminates or restarts the outermost loop of the nested loop structure.
See the code in CalculatorApplet.java.
The applet can be created most easily by modifying the code from Chapter 13 Project 4, DecimalToBinary. Change it from a Swing application to an applet (follow the steps described in the text), and, of course, modify the binary conversion code so it converts to hexadecimal, instead. Fortunately, the same successive division algorithm works, regardless of the base: just change the divisor from 2 to 16 and add code to translate each remainder from a decimal integer value to a hex character code (a switch statement works very nicely, is very readable, and also is usually compiled very efficiently).
