Can a single if-else statement choose one of three options?

Answer:

No. An if-else statement makes a choice between two options.

Nested If for a Three-way Choice

To make a three-way choice, a nested  if  is used. This is where an if-else statement is part of a the true-branch (or false-branch) of another if-else statement. So the nested if-else will execute only when the outer if-else has already made a choice between two branches. Here is a program fragment that makes a choice of one of the three suffixes.

String suffix;

int count=0;    // count is the number of integers added so far.
                // count+1 is the next integer to read

 . . . . 

if ( count+1    )
    suffix = "nd";
else
    if ( count+1   )    // false-branch of first if
        suffix = "rd";                           // false-branch of first if
    else                                         // false-branch of first if
        suffix = "th";                           // false-branch of first if

System.out.println( "Enter the " + 
    (count+1) + suffix + " integer (enter 0 to quit):" );

The false-branch of the first if statement consists of another entire if statement. Fill in the blanks so that:

Fill in the two blanks so that the nested if's make the correct choice.
