Totals are normally initialized to 0. Counters are normally initialized to 0 or 1, depending on how they are used (we will show examples of when to use 0 and when to use 1).Common Error - # 2Using a loop’s counter-control variable in a calculation after the loop often causes a common logic error called an off-by-one-error. In a counter-controlled loop that counts up by one each time through the loop, the loop terminates when the counter’s value is one higher than its last legitimate value (i.e., 11 in the case of counting from 1 to
