A class has four papers in one term. Write a program that will read in a student’s score in four papers as integer and output the student’s average and grade according to the following table.
Average marks >= 80 are A Average marks >= 60 are B Average marks >= 50 are C Average marks >= 40 are D If the student scores less than 40 in any paper the grade will fail.
Use the Switch Statement to display the grade.
Source Code:
#include<iostream.h>
#include<conio.h>
void main()
{
int ch;
cout<<“1. Average or Grade”<<endl;
cout<<“2. Exit”<<endl;
cin>>ch;
switch(ch)
{
case 1:
int tot, avg, oop, dsa, mp, psy;
cout<<“Enter Marks:”<<endl;
cin>>oop>>dsa>>mp>>psy;
tot=avg+oop+dsa+mp+psy;
avg=tot/4;
if(avg>=80)
cout<<“A”;
else if(avg>=60)
cout<<“B”;
else if(avg>=50)
cout<<“C”;
else if(avg>=40)
cout<<“D”;
else
cout<<“Fail”;
break;
case 2:
exit(0);
default:
cout<<“Wrong Choice”;
exit(0);
}
getch();
}
Output:
1. Average or Grade
2. Exit
Enter Your Choice: 1
Enter Marks:
