C++ (CP 123) TEST2 RE-SIT3 2023-2024 SOLVED INTERACTIVE

Question

Madam Rose, a programming instructor at CIVE is used to have timed quiz in every tutorial session. In this digital era, she wants a simple computer program that will be able display the report of one student at a time. The report will have the following information: number of questions attempted, total marks scored, average score per question, and the ranked average score. Every quiz has a total of 5 questions of equal weight (20 Marks Each), a student should attempt all questions in a quiz. Write a C++ program that will accepts student’s marks and print the average score. Table 2 shows the ranked average score.

NOTE:

1. Use function rank() that receive average score from the main function to rank the average score.
2. Use function showrank() that receive the rank from function rank() to print the rank of the average score.

Average Score	Rank
0 – 5	Weak
6 - 10	Normal
11 - 15	Good
16 - 20	Best

#include <iostream>
#include <string>
using namespace std;
 
// Function to determine rank based on average score
string rank(double average) {
    if (average >= 0 && average <= 5) {
        return "Weak";
    } else if (average >= 6 && average <= 10) {
        return "Normal";
    } else if (average >= 11 && average <= 15) {
        return "Good";
    } else if (average >= 16 && average <= 20) {
        return "Best";
    } else {
        return "Invalid";
    }
}
 
// Function to display the rank
void showrank(string rank) {
    cout << "Rank: " << rank << endl;
}
 
int main() {
    const int TOTAL_QUESTIONS = 5;
    const int MAX_MARKS_PER_QUESTION = 20;
    
    int marks[TOTAL_QUESTIONS];
    int totalMarks = 0;
    
    cout << "Enter marks for " << TOTAL_QUESTIONS << " questions (each out of 20):" << endl;
    
    // Accept marks for all questions
    for (int i = 0; i < TOTAL_QUESTIONS; i++) {
        cout << "Question " << (i + 1) << ": ";
        cin >> marks[i];
        
        // Validate input
        while (marks[i] < 0 || marks[i] > MAX_MARKS_PER_QUESTION) {
            cout << "Invalid marks! Enter between 0 and 20: ";
            cin >> marks[i];
        }
        
        totalMarks += marks[i];
    }
    
    // Calculate average score per question
    double average = static_cast<double>(totalMarks) / TOTAL_QUESTIONS;
    
    // Display report
    cout << "\n--- STUDENT QUIZ REPORT ---" << endl;
    cout << "Number of questions attempted: " << TOTAL_QUESTIONS << endl;
    cout << "Total marks scored: " << totalMarks << "/" << (TOTAL_QUESTIONS * MAX_MARKS_PER_QUESTION) << endl;
    cout << "Average score per question: " << average << endl;
    
    // Get and display rank
    string studentRank = rank(average);
    showrank(studentRank);
    
    return 0;
