Thread: Problem with simple piece of code

I'm having a bit of trouble with an excercise for C++ (for reference, I use SSH to connect to my University and code using Unix with g++ compiler).

This simple piece of code (which after much stress over being unable to get the function to work on my own) I copied directly from a sample excercise and it still gives me the following when I try to excecute it: "Segmentation Fault". Can somebody tell me - what's wrong here?

Code:

#include <iostream>
#include <stdlib.h>
using namespace std ;

void main( int argc, char* argv[] )
{
 int  marks[5] ;
 int total = 0 ;

  for ( int i = 0; i < 6; i++)
    {
      marks[i] = atoi(argv[i+1]) ;
    }
}

P.S. Can somebody also explain what a segmentation error is in the first place?
