.Help with Homework Please

Please use Microsoft Visual Studios using the win32 console application and c++ file.

-Use a loop to read in data line by line from the file.

-Calculate and display the average with 2 decimal places.

-Added another famous computer Scientist to input file.

-Count and display number of students.

-Write the same results to a file.

-Output looks like assignment. Spaced correctly

-Extra credit. Famous CS people info.

ouac c Review the Chapter 5 Using Files slides on Canvas and Section 5.12 in your textbook. Download the text file called scores.txt. Save it inside your Project folder. It contains the following data on famous computer scientists their name and 5 exam scores. Grace Hopper 81.5 90.0 65.5 79.9 93.2 Alan Kay 75.5 81.5 70 90 98.2 John Backus 99.0 74 100 87.7 99.9 Sergey Brin 62 100 88.5 79.7 97.3 Brian K Create a new program called FamousCS.cpp. (Our Files Activities will be helpful). The basic structure is: include statements - there will be several using namespace std; int main) //declare variables needed //define file stream object //open the file scores.txt if (successfully opened file) // using a while loop read in and display the data // close the data file else cout \"Error opening file.\" endl ; /lend of else return 0
