Question

Write a program in the C ++ language that executes the following application

1-   Type function to find grade (a, b, c, d, e, fnil)

2-. Write a program that requires the user to enter student marks

3- Use the function to show the student's mark with grade

Answer 1

I WROTE THE CODE ALONG WITH THE COMMENTS:

CODE:

#include <iostream>

using namespace std;

char grade(int);

int main()
{
  
//variables declaration.
int i,n;
char value;
  
cout<<"Enter number of students: ";
cin>>n;
int student_marks[n];
cout<<"Enter student marks: ";
for(i=0;i<n;i++) //for loop used to scan the student_marks.
{
cin>>student_marks[i];
}
cout<<endl;
for(i=0;i<n;i++)
{
value=grade(student_marks[i]); //calling the grade function to find the grade based on marks.
cout<<"Grade of student "<<(i+1)<<": "<<value<<endl;
  
}

return 0;
}
char grade(int marks)
{
//Based on marks different grades will be given.
  
if(marks>=80)
{
return 'A';
}
else if(marks<80 && marks>=79)
{
return 'B';
}
else if(marks<79 && marks>=69)
{
return 'C';
}
else if(marks<69 && marks>=59)
{
return 'D';
}
else if(marks<59 &&marks>=49)
{
return 'E';
}
else
{
return 'F';
}
  
}
