Suppose you need to read 100 numbers, compute their average, and find out how many numbers are above the average. your program first reads the numbers and computes their average, then compares each number with the average to determine whether it is above the average. in order to accomplish this task, the numbers must all be stored in variables. you have to declare 100 variables and repeatedly write almost identical code 100 times. writing a program this way would be impractical. an array, which stores a fixed-size sequential collection of elements of the same type, can be used
