Some error, dunno what

Code:

---

#include <stdio.h>
int main()
{
  int marks[50],i,n,sum=0;
  float avg;
  printf("ENTER THE NUMBER OF STDENTS(should not exceed 50): \n");
  scanf("%d",&n);
  for(i=0;i<=n;i++)
  {
  printf("STUDENT NUMBER %d SCORED:\n",i+1);
  scanf("%d",marks[i]);
  sum+=marks[i];
  }
  avg=sum/n;
  printf("THE AVERAGE MARKS OF STUDENTS ARE %f",avg);
  return 0;
}

Could you please also copy'n'paste the error? I still haven't met any mind reader here.
And please use normal English (no "plzz" and "2" instead of "to").

Code:

---

for(i=0;i<=n;i++)
{
  printf("STUDENT NUMBER %d SCORED:\n",i+1);
  scanf("%d",marks[i]);

---

If n == 50 (or bigger) then "i" will get up to 50 too and marks[i] == marks[50] is undefined behavior.
I.e. your "<=" should be "<".

Edit: And scanf("%d") expects a pointer to int but marks[i] is an int.

Code:

---

avg=sum/n;

---

"sum" is an int, "n" is an int, thus the result of "sum / n" will be an int too and then it will be cast to a float.
