Structure program showing array type has incomplete element type

Question

I am writing simple array program.

#include<stdio.h>

struct Student
{
   int  i;  //Stores address of integer Variable
   char *name; //Stores address of Character String
};

int main()
{
struct student s1[] ={
                        {1,"srini"},
                        {2,"pankaj"},
                        {3,"rajini"}
                      };

printf("\nRoll Number of Student : %d",s1.i);
printf("\nName of Student        : %s",s1.name[0]);

return(0);
}

Showing error as error: array type has incomplete element type

I dont know what I am doing wrong

C is case-sensitive. You define Student as the struct but then use student in the function body.
s1 is an array of Students. To access each element you'll need s1[index], followed by the member selection operator .. Here index is 0, 1, or 2.
Consider using a const char* as the name: this emphasises the fact that you cannot change the read-only string literals.

s1 is an array.

So you should do

printf("\nRoll Number of Student : %d",s1[0].i);
printf("\nName of Student        : %s",s1[0].name);
