C Programming code for Student (max_Marks) Data Structures

Write a Modular C Programming code for Getting details of a Student who took the highest marks.

Read the number of students, read their information and display the details of the students:

CODE:

#include<stdio.h>
struct student
{
char name[20];
int rno;
float marks;
};
struct student s[50];
void read(struct student s[50], int n);
void display(struct student s[50], int n);
void avgmarks(struct student s[50], int n);
void maxmarks(struct student s[50], int n);
int n, i;
main()
{
printf("Enter the no. of students you want to give info: ");
scanf("%d",&n);
printf("\nEnter Details of Student %d",i+1);
read(s,n);
avgmarks(s,n);
maxmarks(s,n);

}
void read(struct student s[50], int n)
{
for(i=0;i<n;i++)
{
printf("\nEnter the Name: ");
scanf("%s",&s[i].name);
printf("Enter the RollNo: ");
scanf("%d",&s[i].rno);
printf("Enter the Marks: ");
scanf("%f",&s[i].marks);
printf("\n+++++++++++++++++++++++++++++++++++++++++++++++++\n");
}
}


void avgmarks(struct student s[50], int n)
{
    int sum=0;
    float avg;
    for(i=0;i<n;i++)
    {
        sum=sum+s[i].marks;
    }

}

void display(struct student s[50], int n)
{

printf("\nName: %s",s[n].name);
printf("\nRollNo: %d",s[n].rno);
printf("\nMarks: %f",s[n].marks);
printf("\n\n+++++++++++++++++++++++++++++++++++++++++++++++++\n");

}

void maxmarks(struct student s[50], int n)
{
    int max=s[0].marks,k;
    for(i=0;i<n;i++) 
{ 
if (s[i].marks>max)
        {
           max=s[i].marks;
           k=i;
        }


    }

printf("The Details of Student who took Highest Marks is:\n");
display(s,k);

}

OUTPUT

Enter the no. of students you want to give info: 5

Enter Details of Student 1
Enter the Name: rhhyt
Enter the RollNo: 67
Enter the Marks: 657

+++++++++++++++++++++++++++++++++++++++++++++++++

Enter the Name: thyju
Enter the RollNo: 657
Enter the Marks: 75

+++++++++++++++++++++++++++++++++++++++++++++++++

Enter the Name: kkkkkk
Enter the RollNo: 7777
Enter the Marks: 8888888

+++++++++++++++++++++++++++++++++++++++++++++++++

Enter the Name: ujy
Enter the RollNo: 78
Enter the Marks: 76

+++++++++++++++++++++++++++++++++++++++++++++++++

Enter the Name: utjy
Enter the RollNo: 67
Enter the Marks: 76

+++++++++++++++++++++++++++++++++++++++++++++++++
The Details of Student who took Highest Marks is:

Name: kkkkkk
RollNo: 7777
Marks: 8888888.000000

+++++++++++++++++++++++++++++++++++++++++++++++++
