Multibranch if-else Statements
Notice how the value of balance in Listing 8.2 determines which of the five different print statements the program will execute. Letting the value of a variable determine which statement (or compound statement) to execute of several possible alternatives is so commonplace in the programming world that a standardized system has been devised for writing the nested if-else structures used to implement this functionality. The resulting structures are called multibranch if-else statements.
Let's have a look at how we can turn Listing 8.2 into this standard style. We start by changing the flowchart of Figure 8.10 to form a new flowchart that yields the same results but follows a couple of standard conventions:
Only the ...
