Question

USE C++ FOR THE CODE THAT CAN RUN IN VISUAL STUDIO 2019 (or a complier)

Write a program YourName-Assignments (replace Your Name with your actual name, no spaces) that reads from students' records (one student per line) in the following format: Last Name Tests Grade Assignments Grade and computes and outputs (to the console) the STUDENT STATISTICS in a table format one line per student: Student Name Total Points Numeric Grade Letter Grade The student statistics should have the exact table header'. The program should also compute and output (to the console) in the table format like below, the CLASS STATISTICS for the entire class: the number of studentso (row Number) and the average numeric grade? (row Average) among all students. All text/character columns should be aligned to the left and all floating-point values align to the right and formatted with 2 decimals. For example, here is the how the output will look for the input bellow: Sample input data file: Sample console output: STUDENT STATISTICS: Anderson Blake Cruz Dang Engberg Farris Garda Hadad Ionescu Johnson Kaloo Lagos Mikhailov Nguyen O'Neil 91.5 75.5 55 95 80 55 93.6 25 100 75 75 55.5 95 195 85 95 90 30 85 100 90 90.5 60 95.5 90 85 80 83.5 100 70 Student Total Numeric Letter Name Points Grade Grade Anderson 186.50 93.25 A Blake 165.50 82.75 B Cruz 85.00 42.50 F Dang 180.00 90.00 А Engberg 180.00 90.00 А Farris 145.00 72.50 с Garcia 184.10 92.05 А Hadad 85.00 42.50 F Ionescu 195.50 97.75 A Johnson 165.00 82.50 B Kaloo 160.00 80.00 B Lagos 135.50 67.75 D Mikhailov 178.50 89.25 B Nguyen 195.00 97.50 A O'Neil 155.00 77.50 с CLASS STATISTICS: Number: 15 Average: 79.85 You can test your program on the attached StudentsGrades.txt (do edit the file), but your program should work on any other files that have the correct format, thus, do not hardcode the output or the number of students. You should write the program in Visual Studio 2019 (using only concepts learned in class so far).

Code:-

#include<iostream>

#include<iomanip>

#include<fstream>

#include<string>

using namespace std;

char getGrade(double score){

if(score>=89.5 && score<=100)

return 'A';

else if(score>=79.5 && score<=89.49)

return 'B';

else if(score>=69.5 && score<=79.49)

return 'C';

else if(score>=59.5 && score<=69.49)

return 'D';

else if(score>=0 && score<=59.49)

return 'F';

}

int main(){

ifstream in;

in.open("StudentsGrades.txt");

if(in.fail()){

cout<<"Unable to open file"<<endl;

return -1;

}

string name;

double test_grade, assign_grade, total_points, numeric_grade;

cout<<setprecision(2)<<fixed;

cout<<"STUDENT STATISTICS"<<endl;

cout<<setw(15)<<left<<"Student Name"<<setw(15)<<"Tests Grade"<<setw(15)<<"Assign. Grade"<<setw(15)<<"Total Points"<<setw(15)<<"Numeric Grade"<<setw(15)<<"Letter Grade"<<endl;

int n = 0;

double avg = 0.0;

while(!in.eof()){

in>>name>>test_grade>>assign_grade;

total_points = test_grade+assign_grade;

numeric_grade = total_points/2.0;

cout<<setw(15)<<left<<name<<setw(15)<<test_grade<<setw(15)<<assign_grade<<setw(15)<<total_points<<setw(15)<<(total_points/2)<<setw(15)<<getGrade(numeric_grade)<<endl;

avg+=numeric_grade;

n++;

}

avg /= n;

cout<<"\nCLASS STATISTICS"<<endl;

cout<<"Number:\t\t"<<n<<endl;

cout<<"Average:\t"<<avg<<endl;

return 0;

}
