Okay so I need help with this c++ code to change it to where it asks the user to enter the file and search. I am going to break the instructions in three parts so you can understand. First, its the book instructions. Then, the what the actual file looks like and the original code. Book instructions First I want you to modify the program to prompt the user for the name of the file to output. The file that is used in the code Today we live in an era where information is processed almost at the speed of light. Through computers, the technological revolution is drastically changing the way we live and communicate with one another. Terms such as “the Internet,” which was unfamiliar just a few years ago, are very common today. With the help of computers you can send letters to, and receive letters from, loved ones within seconds. You no longer need to send a résumé by mail to apply for a job; in many cases you can simply submit your job application via the Internet. You can watch how stocks perform in real time, and instantly buy and sell them. Students regularly “surf” the Internet and use computers to design their classroom projects. They also use powerful word processing software to complete their term papers. Many people maintain and balance their checkbooks on computers.
