Answer to Question #271918 in C++ for Manav Parekh

Question

Hope Michael, a DBIT student did 8 units in an exam and got different marks in each of the exam papers. She intends to calculate her total, mean score and exams verdict for the exams using a program written in C++. Requirements/Guide. (All the instructions below should be done in the same single program)

i. Assign 8 scores to Hope in a one-dimensional array. [2 Marks]

ii. Declare a function that takes an array of Hope’s scores as a parameter and calculates both the total and the mean score. [3 Marks]

iii. Pass the mean score from (ii) above into another function by reference, that computes whether Hope has passed or not given that a pass is 50 – 100 while a fail is 0 – 49.99 Marks. [3 Marks]

iv. Display Hope’s results as follows: (this is a sample output, use arbitrary values in your solution) [2 Marks]

Student Name: Hope Michael

Test Scores: 40, 50, 60, 80, 98, 82, 70, 32

Total Marks: 512

Mean Score: 64

Exams Verdict: Pass 

Answer 1

#include <iostream>


using namespace std;
double calculateTotalAndMean(int arr[]){
    int total=0;
    for(int i=0;i<8;i++){
        total+=arr[i];
    }
    double mean=(total/8.0);
    return mean;
}


string passOrFail(double n){
    if(n>=50 && n<=100){
        return "Pass";
    }
    else if(n>=0 && n<=49.99){
        return "Fail";
    }
    return "";
}


int main()
{
    int scores[]={40, 50, 60, 80, 98, 82, 70, 32};
    cout<<"\nTest Scores: ";
    for(int i=0;i<8;i++){
        cout<<scores[i]<<", ";
    }
    cout<<"\nTotal Marks: "<<calculateTotalAndMean(scores)*8;
    cout<<"\nMean Score: "<<calculateTotalAndMean(scores);
    cout<<"\nExams Verdict: "<<passOrFail(calculateTotalAndMean(scores));
    return 0;
