Program to understand how structure members are sent to a function

#include<stdio.h>
#include<string.h>
struct student
{
char name[20];
int rollno;
int marks;
};
void display(char name[ ], int rollno, int marks);
main( )
{
struct student stu1 = {"John", 12 , 87 };
struct student stu2;
strcpy(stu2.name, "Mary");
stu2.rollno = 18;
stu2.marks = 90;
display(stu1.name, stu1.rollno, stu1.marks);
display(stu2.name, stu2.rollno, stu2.marks);
}
void display(char name[ ], int rollno, int marks)
{
printf("Name   - %s\t", name);
printf("Rollno - %d\t", rollno);
printf("Marks  - %d\n", marks);
}
