File I/O Exercise:

• Using the lab samples as a starting point, write a program called lab4.cpp to input 10 float values from an input file input.txt.
  (Hint, you have to create the input.txt file yourself)
• Output the sum and the average of the 10 float values to an output file output.txt.
• Be sure to test to see if you opened the input and output files before you use them.
• Compile and run this C++ program.
• Run the program for your lab instructor and show the result in output.txt.
