This assignment is for c$++,$ and I am not sure if the instructors wants us to use GitHub since her instructions are not clear and I cannot get a hold of her for more instructions. Any help is greatly appreciated!

$1.$ Write a program that carries out the following tasks:

Open a file with the name hello.txt$.$

Store the message $$Hello$,$ World!$$ in the file.

Close the file.

Open the same file again.

Read the message into a string variable and print it$.$

$2.$ Write a program that reads a text file containing floating$-$point numbers. Print the average of the numbers in the file. Prompt the user for the file name.
