The conditional expression is just as cryptic as the last two, but once again it can be very useful so it would pay you to understand it. It consists of three expressions within parentheses separated by a question mark and a colon. The expression prior to the question mark is evaluated to determine if it is not true, the expression following the colon is evaluated. The result of the evaluation is used for the assignment. The final result is identical to that of an "if" statement with an "else" clause. This is illustrated by the second example in this group. The conditional expression has the added advantage of more compact code that will compile to fewer machine
instructions in the final program.
The final two lines of this example program are given to illustrate a very compact way to assign the greater of two variables "a" or "b" to "c", and to assign the lessor of the same two variables to "c". Notice how efficient the code is in these two example.
