Find students grades through structure

Q. Write a C program using structure to find student grades in a class. Make necessary assumption.

Ans.

Before writing program we make some assumption as following :

Maximum total marks is 500.     

  Student_percentage         Grades

     >=80                        A

     >=60                        B

     >=50                        C

     >=40                        D

     <40                         F

  

/*C program to find students grades in a class through structure */

#include<stdio.h>

#include<conio.h>

struct stud

{
  char nam[20];

  int obtain_mark;

  int per;

  char grad[5];

};

struct stud s[5];

int i;

int main()

{

 for(i=1; i<=5; i++)

 {

  printf("Enter %d student name : ",i);

  scanf("%s",&s[i].nam);
  printf("Enter %d student obtained marks = ",i);
  scanf("%d",&s[i].obtain_mark);
  fflush(stdin);

 }

 for(i=1; i<=5; i++)
   s[i].per=s[i].obtain_mark/5;
 for(i=1; i<=5; i++)
 {

  if(s[i].per>=80)

    strcpy(s[i].grad,"A");

  else if(s[i].per>=60)

    strcpy(s[i].grad,"B");

  else if(s[i].per>=50)

    strcpy(s[i].grad,"C");

  else if(s[i].per>=40)

    strcpy(s[i].grad,"D");

  else

    strcpy(s[i].grad,"F");
 }

 for(i=1; i<=5; i++)

  printf("\n%d student %s has obtained grade %s ",i,s[i].nam,s[i].grad);
 getch();

 return 0;

}

  Output of above programe :

Enter 1 student name : John
Enter 1 student obtained marks : 250

Enter 2 student name : Robert
Enter 2 student obtained marks : 410

Enter 3 student name : Isabell
Enter 3 student obtained marks : 386

Enter 4 student name : Adem
Enter 4 student obtained marks :197

Enter 5 student name :Harry
Enter 5 student obtained marks : 490 

1 student Jhon has obtained grade C
2 student Robert has obtained grade A

3 student Isabell has obtained grade B

4 student Adem has obtained grade F

5 student Harry has obtained grade A
