Question

Attached is a text file full of names. Write a program that prompts the user to type in a name. If the name appears in the list of names, the program prints a message indicating the name was found. If the name entered by the user is not in the database, the program prints a different message indicating the name was not found. The program will continue prompting the user and searching for names until the user enters "quit".

The text file is named:   names_fall2020.txt

Please solve using C++

Thanks!

       found = false;
       in.open("names_fall2020.txt");
       cout<<"Enter name to search : ";
       getline(cin , userInput);
      
       if(userInput == "quit") break;
      
       while(getline(in , name)){
           if(name == userInput){
               found = true;
               break;
           }
       }
