Write a program to print student grade using structure.

AIM

To write a program to print student grade using structure.

ALGORITHM

Step‒1: Start

Step-2 : Define structure stud with the following members

rollno integer

name[30] character

mark1,mark2, mark3, total: integer

avg: float

grade character

End stud

Step-3 : Read input n

Step-4 : Set a loop to get record details

Step-5 : Read a[i].rollno, a[i].name

Step-6 : a[i].mark1, a[i].mark2, a[i].mark3

Step-7 : a[i].total=a[i] + mark1+a[i].mark2+a[i].mark3

Step-8 : a[i].avg=a[i].total/3

Step-9 : [End of step‒4]

Step-10 : Check if a[i].avg <40 then assign a[i].grade = D

Step‒11 : Check if a[i].avg <60 then assign a[i].grade = C

Step‒12 : Check if a[i].avg< 80 then assign a[i].grade = B else

Step‒13 : a[i].grade='A'

Step‒14 : Print a[i].rollno, a[i].name, a[i].mark1, a[i].mark2,

a[i].mark3,a[i].total, a[i].avg, a[i].grade

Step‒15 : Stop

FLOWCHART

PROGRAM

#include<stdio.h>

#include<conio.h>

struct stud

{

int rollno;

char name[30];

int mark1,mark2,mark3,total;

float avg;

char grade;

}a[25];

void main()

{

int i,n;

printf("Enter the number of students :");

scanf("%d",&n);

for(i=0;i<n;i++)

{

printf("Enter the student %d details :",i+1);

printf("\nRollNo:");

scanf("%d",a[i].rollno);

printf("Name:");

scanf("%s",a[i].name);

printf("Mark 1: ");

scanf("%d",&a[i].mark1);

printf("Mark 2:");

scanf("%d",&a[i].mark2);

printf("Mark 3:");

scanf("%d",&a[i].mark3);

a[i].total=a[i].mark1+a[i].mark2+a[i].mark3;

a[i].avg=a[i].total/3;

if(a[i].avg<40)

a[i].grade = 'D';

else if (a[i].avg<60)

a[i].grade='c';

else if (a[i].avg<80)

a[i].grade='B';

else

a[i].grade='a';

}

printf("\t\tStudents mark details: \n");

printf("\n Rollno\t Name \t\tmark 1\tmark 2\tmark3\ttotal\taverage");

for(i=0;i<n;i++)

printf("\n%d\t%s\t\t%d\t%d\t%d\t%d%.2f\t%c",a[i].rollno,a[i].name, a[i].mark1,a[i].mark2,a[i].mark3,a[i].total,a[i].avg,a[i].grade);

}

OUTPUT

Enter the number of students :2

Enter the student 1 details :

RollNo:100

Name:Muni

Mark 1: 89

Mark: 2:80

Mark 3:76

Enter the student 2 details :

RollNo:101

Name:Mahi

Mark 1: 87

Mark: 2:90

Mark 3:67

Students mark details:

Rollno Namemark1 mark2 mark3 total average Grade

100 Muni 89 80 76 245 81.00 A

101 Mahi 87 90 67 244 81.00 A
