Bookmarks window Help 0 When the user runs the program, they shall be greeted with a menu of options like what is shown selects "E" to exit (at which point the program shall stop). below. This menu shall be repeated to the user (over and over) unal the user tinaly Fees Pai like to do (h-Add record to 1 W-Write al1 records prompted to enter a struct (record), this record shall be added to the end of your struct list, and a report shall be record that was just added to the end of the list printod that shows the ne user chooses "W", the program shall write all the structs (one struct per line) to a text file. ?ifthe user chooses ?, the program shall read allthe struct data from a text fle (one line holds one struct). This operaen st al replace to ament struct array. Then, the program shall print a report showing all the struct data Gust read from the text file). Design Specifications Your program shall meet the following design and coding specifications 1. The top of the program shall contain these comments: o homework name ('Text File") o your name and the date you completed your program file that contains my input functions but this is not 2. Remember to include the two header files that provide String functionality. I also recommend that you reference a header mandatory #ine lude tring.b fineludeExplanation / Answer
