Modify the program similar to the eBook Collection Program! (The
program should only display the multiplication table and not ask
the users any input. MAKE SURE TO DETERMINE WHETHER THE FILE WAS
OPENED!!!)
(Use if statements to open and close inFile and OutFile
)
Ex: if (outFile.is_open())
outFile.close();
if(inFile.is_open())
inFile.close();
