C++

Write a program that reads a telephone number from a file called number.dat. This program should determine whether the input is a valid telephone number. A valid telephone number has the following syntax:

D D D - D D D - D D D D : the first D can't be a zero (0).

If the telephone number is valid, the program should print the telephone number followed by a colon (:) followed by a space and the word Valid.

If the telephone number is invalid, the program should print the telephone number follow by a colon (:) followed by a space and the words Not Valid and ask for another telephone number but this time the input should come from the keyboard.

The programs should keep ask until the telephone number is valid.
