• Write programs using file I/O
• Design programs with looping logic
Task 1
Download the file named random.txt. This file contains a long list of random numbers. Copy
the file to your program development folder, then write a program readFile.cpp that opens
the file, reads all the numbers from the file, and calculates the following:
1) The number of numbers in the file
2) The sum of all the numbers in the file (a running total)
3) The average of all the numbers in the file
The program should display the number of numbers found in the file, the sum of the numbers,
and the average of the numbers. It also needs to write these results to an output file named
results.txt.
Task 1 Sample Output
Number of numbers: 200
Sum of the numbers: 105527
Average of the numbers: 527.635
Task 2
Write a program minmax.cpp with a loop that lets the user enter a series of integers. The user
should enter -99 to signal the end of the series. After all the numbers have been entered, the
program should display the largest and smallest numbers entered.

Task 2 Sample Output
You will enter a series of integers and I will then tell you
the largest and the smallest numbers you entered.
Enter -99 to terminate the series.
Enter an integer (-99 to quit): 245
Enter another integer (-99 to quit): 333
Enter another integer (-99 to quit): 457
Enter another integer (-99 to quit): 822
Enter another integer (-99 to quit): 29
Enter another integer (-99 to quit): 100
Enter another integer (-99 to quit): 31
Enter another integer (-99 to quit): 22
Enter another integer (-99 to quit): 144
Enter another integer (-99 to quit): -99
The max number you entered is 822.
The min number you entered is 22.
Note
Copy and paste your console outputs after the end of your source file. Remember to comment
the output with /* and */ or multiple //.
Avoid cryptic variable names and poor indentations.
