This STATEMENT A box represents the code to execute
if the first Boolean Expression is true.


Example:



if (num == 0)                           if (BOOLEAN 1)
   printf ("num equals 0\n");              STATEMENT A 
else                                    else
   if (num < 0)                            if (BOOLEAN 2)
      printf ("num is negative\n");           STATEMENT B
   else                                    else
      printf ("num is positive\n");           STATEMENT C



In the example above, the first Boolean Expression is:

(num == 0)

If it is true, the code to execute (STATEMENT A) is:

 printf ("num equals 0\n"); 

After executing this code, the IF ELSE IF ELSE statement
is finished, and execution goes to the rest of the
program.
