1. Create a file named score.txt that holds the name, id, and score of each student in a course. Assume that the maximum enrollment in the class is 30. The following is a sample file: 1000 Alicia 1000 Tom 79.5 97.5 Ben 2000 87 Joaquin 1500 Sisana 5e00 70.55 Write a program named lab3.cpp that reads a filename from a user. You will define a struct that is able to hold information about a single student. Then, you will declare an array of structs of the data type you create, and populate it with the information from the file. Your program needs to display the name, id, and score of each student in ascending order of ids. A sample run of your program might look like: Enter a file name: score.txt 1000 79.5 Tom Joaquin 1500 Ben Alicia 3000 Susana sO00 2000 97.5 70.55 In addition to creating your own struct array, you'll need to brush up on reading from files, as well as sorting arrays. To format the output, you may want to include the iomanip library, and then use left and setw), for example: cout left e setw(8) << section[i].name.. Here is some sample code to get your started: sinclude <iostrean> // to use keyboard input and output include cfstream> // to use files winclude <cstdlib> // include cionanip> // to use setw() using nanespace std; struct student
