Question

in C++

Create a program that will calculate a student’s grade average of 5 test scores and assign a letter grade for a student. The program should use a class to store the student’s data including the student’s name and score on each of 5 tests. The program should include member functions to 1) get the student’s test scores, 2) calculate the average of the test scores, and 3) display the results as follows:

Test scores for Mary:

100

90

75

80

98

The average of the scores is 88

Mary’s grade is B

/* Below is your required code */

#include <iostream>
#include<string>
using namespace std;
class student{
public:
string name;
int marks[5];
float avg=0;
void get(){
cout<<"Enter name of student = ";
cin>>name;
for(int i=0;i<5;i++){
cout<<"Enter marks in "<<i+1<<"th subject : ";
cin>>marks[i];
}
}
void getaverage(){
  
for(int i=0;i<5;i++){
avg+=marks[i];
}
avg/=5;
}
void display(){
cout<<"Test scores for "<<name;
for(int i=0;i<5;i++)
cout<<endl<<marks[i];
char grade;
cout<<"\nThe average of the scores is "<<avg;
if(avg>=90) grade='A';
else if(avg>=80) grade='B';
else if(avg>=70) grade='C';
else if(avg>=60) grade='D';
else if(avg>=50) grade='E';
else
grade='F';
cout<<endl<<name<<"'s grade is "<<grade;

}


};
int main()
{
student s;
s.get();
s.getaverage();
s.display();

return 0;
}
