why does assigning value to array struct not working C

Question

Im am trying to write a program that collects the information of students. I am using an array of students(structs)

typedef struct {
  char name[50];
  struct Course* course;
}Student;

and in my main() i did this

Student* stds = (Student*) malloc(app.std_cnt * sizeof(*stds) );

getStdData(stds);

here is the getStdData function

void getStdData(struct Student *students){

 int i;
 char name[50];

 Student std;

 printf("\n");

 for(i = 0; i < app.std_cnt; i++){

    printf("std [%i] name : ",i+1);


    scanf("%s",&name);

    strcpy(std.name,name);

    students[i] = std;

 }
}

when i compile i get

gpa.c
gpa.c(124): error C2440: '=': cannot convert from 'Student' to 'Student'

can anyone tell me what i'm doing wrong? and why is is complaning about a Student to Student conversion? are they not of the same type?

In C, struct Student and Student may be two different types. Student comes from your typedef and struct Student would come from

struct Student { /* ... */ };

So your function should be

void getStdData(Student *students)

For a good discussion of the situation, consider this answer.

how then can i print the array? – Medunoye Laxus Gbenga Jun 04 '16 at 19:40
Just change the function declaration as I suggest (remove the `struct` from `void getStdData(struct Student *students){`) – hcs Jun 04 '16 at 19:43
sorry...was asking something else. – Medunoye Laxus Gbenga Jun 04 '16 at 19:49
I see, I was confused because it looks like your code is already printing the array, I didn't notice that you are just printing the index. – hcs Jun 04 '16 at 19:55
