Question

Note: Please do this in C++

Currently, Marvel Academy's student grade records are stored parallel arrays string names []"Spider-Man", "Iron Man","Black Panther","Dr. Strange", "Thor"i int exams[1 [4- 98,96, 93,88, 60, 91,99,74 95, 85,94,88 t 100,100, 99,100, 58, 83,76,60 We want to convert these to a dynamic array of structures with an additional exam average field Your tasks are: 1. define a structure for student grade records 2. declare a dynamic array of structures 3. populate the structures from the parallel arrays 4. define a function to compute the average for a student and populate average field 5. define a function to display name and average for a student. The average should be printed to two decimal places. 6. demonstrate your functions and program by printing the name and average for each student 1. Correctness (meets specification) 2. Design (well-constructed solution) 3. Validation & Verification (Testing) 4. Style (readable for your client - me) Total 10 points 5 points Example output Name: Spider-Man Average: 93.75 Name: Iron Man Average: 81.00 Name: Black Panther Average: 90.50 Name: Dr. strange Average: 99.75 Name: Thor Average: 69.25

Answer 1

#include <iostream>

#include <iomanip>

#include <string>

using namespace std;

// Defining structure to store Student Grade records

struct Student {

string name;

int s1;

int s2;

int s3;

int s4;

float avg_grade;

};

//Defining function to compute average for a student

float average_grade(float a,float b,float c,float d){

float avg=(a+b+c+d)/4;

return avg;

}

//Defining function to display the details in array

void display(Student m[5])

{

cout << "Displaying array contents: "<< endl;

for (int i = 0; i < 5; i++)

{

cout << "Name: " << m[i].name << endl;

cout <<"Average: " <<fixed<<setprecision(2)<< m[i].avg_grade <<"\n"<<endl;

}

}

int main()

{

string names[]={"Spider_man","Iron_man","Black_panther","Dr.Strange","Thor"};

float exams[][4]={{98,96,93,88},{60,91,99,74},{95,85,94,88},{100,100,99,100},{58,83,76,60}};

Student* GradeList;

GradeList = new (nothrow) Student[5]; //created dynamic array of structures

for(int i=0;i<5;i++){ //floating the dynamic array with the students details

GradeList[i].name = names[i];

GradeList[i].s1=exams[i][0];

GradeList[i].s2=exams[i][1];

GradeList[i].s3=exams[i][2];

GradeList[i].s4=exams[i][3];

GradeList[i].avg_grade = average_grade(exams[i][0],exams[i][1],exams[i][2],exams[i][3]); //storing average

}  

display(GradeList);

return 0;
