"processor fault"

[jimhakans]

#include<stdio.h>
main()
{
  int mark[25][4],j,i;
  for(j=0;j<25;j++)
  {
    for(i=0;i<4;i++)
    {
      printf("\nEnter you marks\n");
      scanf("%d",marks[j][i]);
    }
  }
}
 

This is a simple program of inputing marks in the four tests for each of the 25 students. But when i run it, it only ask one time to input the marks and then it shows a message "processor fault". What is i am doing wrong here, plz help.

scanf takes a pointer not an integer so you need

      scanf("%d",&marks[j][i]);
 

Also main returns int and not doing so invokes undefined behaviour, anything may happen.
