Q&A

Q1:	How do you choose between if...else and switch?
A1:	If there are more than just one or two else clauses, and all are testing the same value, consider using a switch statement.
Q2:	How do you choose between while and do...while?
A2:	If the body of the loop should always execute at least once, consider a do...while loop; otherwise try to use the while loop.
Q3:	How do you choose between while and for?
A3:	If you are initializing a counting variable, testing that variable and incrementing it each time through the loop, consider the for loop. If your variable is already initialized and is not incremented on each loop, a while loop might be the better choice.
Q4:	Is it better to use while(1) or for(;;)?
A4:	There is no significant difference.
