Write a C program to read and store the roll no and marks of 20 students using array

Define a structure, student, to store the following data about a student:
Roll number (int), Marks (int)

Suppose that the class has 20 students. use an array of 20 elements of type student.
create a function to read the student's data into the array. 

  •  Program:

#include<stdio.h>
#include<conio.h>

int main()
{
   int a[20], b[20], i;
   for(i=0; i<20; i++)
   {
      printf("Enter roll number [%d]",i+1);
      scanf("%d",&a[i]);
      printf("Enter marks [%d]",i+1);
      scanf("%d",&b[i]);
   }
   for(i=0; i<20; i++)
   {
      printf("\n Roll number: %d Marks is: %d",a[i],b[i]);
   }   
   getch();
   return 0;
}

  •  Output:

Enter roll number [1]: 3
