In this exercise, you are to modify the Classify Numbers programming example in this chapter. As written, the program inputs the data from the standard input device (keyboard) and outputs the results on the standard output device (screen). The program can process only 20 numbers. Rewrite the program to incorporate the following requirements:a. Data to the program is input from a file of an unspecified length; that is, the program does not know in advance how many numbers are in the file. b. Save the output of the program in a file.c. Modify the function getNumber so that it reads a number from the input file (opened in the function main), outputs the number to the output file (opened in the function main), and sends the number read to the function main. Print only 10 numbers per line.d. Have the program find the sum and average of the numbers.e. Modify the function printResult so that it outputs the final results to the output file (opened in the function main). Other than outputting the appropriate counts, this new definition of the function printResult should also output the sum and average of the numbers.

Question

In this exercise, you are to modify the Classify Numbers programming example in this chapter. As written, the program inputs the data from the standard input device (keyboard) and outputs the results on the standard output device (screen). The program can process only 20 numbers. Rewrite the program to incorporate the following requirements:
a. Data to the program is input from a file of an unspecified length; that is, the program does not know in advance how many numbers are in the file.

b. Save the output of the program in a file.
c. Modify the function getNumber so that it reads a number from the input file (opened in the function main), outputs the number to the output file (opened in the function main), and sends the number read to the function main. Print only 10 numbers per line.
d. Have the program find the sum and average of the numbers.
e. Modify the function printResult so that it outputs the final results to the output file (opened in the function main). Other than outputting the appropriate counts, this new definition of the function printResult should also output the sum and average of the numbers.
