A counter is a numeric variable used for counting something, such as the number of employees paid in a week. You initialize a counter to assign a beginning value to it, and a counter is usually initialized to the number 0. You update a counter by adding a number to or subtracting a number from the value stored in the counter. A counter is always updated by a constant number, and it is updated each time the loop instructions are processed.
