Question

We have a file that contains a list of an unknown amount of integer values. The end of the list is marked by a sentinel number, -987. The file is located at "extracredit\progdata.txt."

Write a program that will read each value from the file, then display it using cout. It should not display the final sentinel value.

After it displays the last value, it should display the maximum of the values, saying "The largest number was ____."

The program should check to see if the file successfully opened. If it did not open successfully, it should just say "File did not open" and not attempt to process any values.

any help for this extra credit question? its for c++
