Specifications

• For the view and delete commands, display an error message if the user enters an invalid contact number.

• Define a structure to store the data for each contact.

• When you start the program, it should read the contacts from the tab-delimited text file and store them in a vector of contact objects.

•When reading data from the text file, you can read all text up to the next tab by adding a tab character ('\t') as the third argument of the getline() function.

•When you add or delete a contact, the change should be saved to the text file immediately. That way, no changes are lost, even if the program crashes later
