Question

Write a program in C++ that finds the count of a number in a list of integers from a text file named input.txt.

- The output will be written to ouput.txt and will count up to the largest number in the list and display how many times each number appears.

- The program must first check if input.txt exists.

- The maximum /minimum and total amount will be displayed.

- You must use functions (the more functions you use, the easier it will be to debug).

- Add comments to your code thoroughly explaining the logic.

- Libraries you may use: #include <iostream>, #include <string>, #include <fstream>, #include <iomanip>, #include <cmath>, #include <vector>, #include <ctime>

- You may use vectors, arrays, and searching & sorting methods

Ex:

input.txt has:
3, 4, 3, 7, 1, 7, 3, 6
output.txt has:
1:* (1) //asterisks show how many times the number appears
2: (0)//columns must be aligned
3:
(3)
4:* (1)
5: (0)
6:* (1)
7:** (2)
Max: 7
Min: 1
There are 8 numbers.
