In Class Assignment Ch$.13($C$++)$

$-$ Write a program that asks the user for the name of a text file. The program should display the first $10$ lines of the file on the screen. If the file has fewer than $10$ lines, the entire file should be displayed along with a message indicating the entire file has been displayed.

$-$ Create your own text file. Test the program with the file having $10$ lines, $10+$ lines, and less than $10$ lines.

$-$ Do error checking on the file "open" to make sure it opened correctly. Test file for file error $($not found or incorrect name$).$

$-$ NOTE: To use a variable "filename" entered by the user, open as follows:

fstream infile $($filename$.$data$())$ or

fstream infile $($filename$.$c$\_$str$())$
