Question

1. Write programming code in C++ for school-based grading system. The program should accept the Subject and the number of students from a user and store their details in an array of type Student (class). The student class should have: • studName, indexNo, remarks as variables of type string, marks as integer, and grade as char. • A void function called getData which is used to get students’ details (index number, name, and marks). • A void function called calculate which will work on the marks entered for a student and give the corresponding grade and remarks as give below. Marks Grade Remarks 70 – 100 A Excellent 60 – 69 B Very Good 50 – 59 C Pass 0 – 49 F Fail • Should be able to display the results for all students (index number, name, marks, grade, remarks). 2. Draw a flowchart for the calculate function above

Answer 1

In this program, I am using the school-based grading system and the program should accept the subject and the number of students.

Program approach:-

• Using the necessary header file.
• Using the standard I/O namespace function.
• Define the main function.
• Declare the variable.
• Display enter obtain marks in 5 subjects.
• Return the value.

Program:-

//header file

#include<iostream>

//using namespace

using namespace std;

//main method

int main()

{

//declare variable

  int j;

  float mark, sum=0, a;

//display enter obtain marks in 5 subjects

  cout<<"Enter Marks obtained in 5 Subjects: ";

  for(j=0; j<5; j++)

  {

      cin>>mark;

      sum = sum+mark;

  }

  a = sum/5;

//display grade

  cout<<"\nGrade = ";

  if(a>=91 && a<=100)

//display a1

      cout<<"a1";

  else if(a>=81 && a<91)

//display a2

      cout<<"a2";

  else if(a>=71 && a<81)

      cout<<"b1";

  else if(a>=61 && a<71)

      cout<<"b2";

  else if(a>=51 && a<61)

//display c1

      cout<<"c1";

  else if(a>=41 && a<51)

//display c2

      cout<<"c2";

  else if(a>=33 && a<41)

//display d

      cout<<"d";

  else if(a>=21 && a<33)

//display e1

      cout<<"e1";

  else if(a>=0 && a<21)

//display e2

      cout<<"e2";

  else

//display invalid

      cout<<"Invalid!";

  cout<<endl;

//return the value

  return 0;
