Describe Loop Errors and symptoms?

Loop Errors:

• Loop errors break down into several different subtypes.
• They occur around a loop construct in a program.
• Infinite loops, off-by-one loops, and improperly exited loops.

Symptoms

• If your program simply locks up, repeatedly displays the same data over and over, or infinitely displays the same message box, you should immediately suspect an infinite loop error.
• Off-by-one loop errors are quite often seen in processes that perform calculations.
• If a hand calculation shows that the total or final sum is incorrect by the last data point, you can quickly surmise that an off-by-one loop error is to blame.
• Likewise, if you were using graphics software and saw all of the points on the screen, but the last two were unconnected, you would suspect an off-by-one error.
