Chapter 4, Problem 4.30E

(Replacing switch with if ... else)Rewrite the program of Fig. 4.7 by replacing the switch statement with a nested if ... else statement; be careful to deal with the default case properly Then rewrite this new version by replacing the nested if ... else statement with a series of if statements; here, too, be careful to deal with the default case properly (this is more difficult than in the nested if … else version). This exercise demonstrates that switch is a convenience and that any switch statement can be written with only single-selection statements.
