The console window may be hidden behind other open windows, so you may have to click on the second task to bring the console window to the front. CONSOLE END-OF-OUTPUT CHARACTER Because console output is persistent, multiple outputs can appear on the same line. The ending position of the current output (and therefore the starting position of the next console I/O) is indicated with the end-of-output symbol (§). Figure 3-4 illustrates how the end-of-output symbol determines the starting location of the next line of I/O.

Not necessarily. If, for example, one of the solutions is much easier to understand than the others, then that solution would be better. Given the choice, you should use the algorithm you understand best. In addition, some solutions lend themselves to modification better than others. ” Solution 1: Nested Conditions Dr. Taylor hands out the first solution (Figure 2-6). “This first solution uses nested conditions. The first condition determines which is the smaller of A and B. The smaller of A and B is then compared with C via a nested condition.

In Visual Logic, the IF flowchart element is a diamond containing a condition and two exit arrows labeled True and False. » A condition is a boolean expression, typically involving one of six relational operators. » When executed, the condition is evaluated. If the condition is true, control flows » along the true arrow. If the condition is false, control flows along the false arrow. An IF statement ends where the true and false branches reconnect. NESTED IF STATEMENTS The true and false branches of an IF statement may contain any number of statements of any type, including other IF statements.
