rainfall Reads a sequence of rainfall measurements from the standard input and writes a summary to the standard output. INPUT The input format is a sequence of measurements represented as unitless, non-negative numbers, written in ASCII, one per line: 12.5 18 7 0 4 Any noise in the input---blank lines, non-numeric text, negative numbers---should be ignored: seven -9 The input terminates with either EOF or a line 999. OUTPUT The program computes three quantities: the mean (valid) measurement, the count of measurements in the interval [mean - 5, mean), and the count of measurements in the interval (mean, mean + 5]. It prints the results in this format: Mean rainfall: 8.3 cm Below count: 1 Above count: 2
