Write a simple telephone directory program in C++ that looks up aphone numbers in a file containing a list of names and phone numbers. The user should be prompted to enter a first and last name, and the progam should then either output the corresponding number or indicate that the name isn't present in the directory. After each lookup the program should ask the user whether he or she wants to look up another numbers and then eithher repeat the process or exit the program. The data on the file should be organized so that each line contains a first name, a last name, and a telephone number separated by blanks. You can return to the beginning of the file by closing it and opening it again.

Type/paste the following into an input file named infile.txt. Add 1 name and number of your choice.

Harry Keeling (202)806-4830 Frank James (301)123-3459 Arthur Paul (202)865-9090 Todd Shurn (410)560-8909 

Requirements

The program should use functional decomposition to solve this problem and code the solution using a void function named lookup_name with three reference parameters( myfile, fullname, phone_number). Also, your program must use a for loop to lookup the telephone number. Prompting the user for first name and last name can be done in either functions, however the main should output the results from the look_up function.

A MATCH is denoted by the phone_number variable not being an empty string (phone_number != ""). Use the following prototype:

void lookup_name(ifstream&, string&, string&); // prototype 

Here is what your output should look like::
