Errors in Code(C++)

[melvin2898]

I am in no ways asking to do my homework. I've run into an error and I need clear instructions on how to fix it. Randomtext.cpp is the file that I saved from the teacher. Apparently it's over used? I don't know what should be named randomtext and what can be named something else.
Here's what the homework says.
" The attached file contains a long list of random numbers (Random.txt).
1. Copy the file to your hard drive.
2. Then write a program that asks user to enter the file name to open and validates that the file is successfully open.
3. Once the user opens the file (Random.txt) successfully, your program should calculate the following:
A) The number of numbers in the file:
B) The sum of all the numbers in the file:
C) The average of all the numbers in the file:
