1. Type in the above program as mileage.cpp. Compile.

2. Create a text file called inmpg.txt. It should contain the starting and ending miles on your odometer and the four gallon amounts. This file should contain no text, only numeric values separated by blanks.

EXAMPLE INMPG.TXT

67308.0 68750.5 11.7 14.3 12.2 8.5

3. Run the program and list the output file (open outmpg.txt). Take screenshot of input and output file, and paste to a word document.

4. In the input file, change starting and ending miles to: 42003 42003

5. Run. Change the program so it works correctly and run again.

Submit the final program, both input files and both output files.
