Question

Help me write the program in C++ Thanks

Program #1: Calculate a student's grade for a class. The class has 4 categories of grades. Each category has different weights. The student's report should include the student's first and last name; course; semester, category listing with weight for each category, grades for each category and the student's final average with a letter grade. Categories with weights: 1. Exams: 30%(3 @ 10% each) 2. Labs: 30% (3 labs @ 10% cach) 3. Project: 30% (1 project) 4. Quizzes: 10% (3 quizzes)

CODE

#include <iostream> using namespace std; char getGrade(int score) if(score >= 90) return 'A'; if(score >= 80) return 'B'; if(score >= 70) return 'C'; if(score >= 60) return 'D': return 'F'; 17 - int main() { string fname, lname, course, semester; cout << "Enter first name followed by last name: "; cin >> fname >> Iname; cout << "Enter course followed by semester: "; cin >> course >> semester; cout << endl; float el, ez, e3, 11, 12, 13, proj, 41, 42, 43, e, 1, 4, finale; cin >> el >> e2 >> e3; cin >> 11 >> 12 >> 13; cin >> proj; cin >> 91 >> 92 >> 93; e = (el+e2-e3) / 3.0; 1 = (11+12+13) / 3.0; q = (91+q2+93) / 3.0; cout << "First name is " << fname << endl; cout << "Last name is " << lname << endl; cout << "Course is " << course << endl; cout << "Semester is" << semester << endl; cout << endl << "Exams Grade is " << getGrade(e) << endl << "\t Examl = " << el << endl << "\t Exam2 = " << e2 << endl << "\t Exam3 = " << e> << endl; cout << endl << "Labs Grade is " << getGrade(1) << endl << "\t Lab1 = " << 11 << endl << "\t Lab2 = " << 12 << endl << "\t Lab3 = " << 13 << endl; cout << endl << "Project = " << proj << endl; cout << "Project grade is " << getGrade (proj) << endl; cout << endl << "Quizzes Grade is " « getGrade() << endl << "\t Quizi = " << 91 << endl << "\t Quiz2 = " << 92 << endl << "\t Quiz3 = " << 93 << endl; finale = e*8.3 + 1*0.3 + proj 0.3 + q*0.1; cout << endl << "Final score = " << finale << endl; cout << "Final grade = " << getgrade(finale) << endl; 51 }

SAMPLE INPUT

John
Nash
Computers
Three
60 80 70.5
49 28 60
97
70 76 79

SAMPLE OUTPUT

First name is John Last name is Nash Course is Computers Semester is Three Exams Grade is C Exam1 = 60 Exam2 = 80 Exam3 = 70.5 Labs Grade is F Lab1 = 49 Lab2 = 28 Lab3 = 60 Project = 97 Project grade is A Quizzes Grade is C Quiz1 = 70 Quiz2 = 76 Quiz3 = 79 Final score = 71.35 Final grade = C
