I'm having trouble with this bit of code I've got for college.  It compiles fine but as soon as it runs it comes back with an illegal operation.  I just con't figure it out!  Can anyone help??

 

 

 

// I N C L U D E S ////////////////////////////////////////////////////////////

 

#include <stdio.h>
#include <stdlib.h>
#include <math.h>

 

 

 

// M A I N ////////////////////////////////////////////////////////////////////

 

void main(void)
{

 

int done=0,        // exit flag
    number,        // the random nunber
    num_tries=0,   // number of tries
    guess;         // the players guess

 

unsigned int *clock = (unsigned int *)0x000046CL; // pointer to clock

 

// SECTION 1 //////////////////////////////////////////////////////////////////

 

// print out introductory instructions

 

printf("\nI'm thinking of a number from 1-100.");
printf("\nTry and guess it!\n");

 

// seed the random number generator with the time

 

srand(*clock);

 

// choose a random number from 1-100

 

number = 1 + rand() % 100;

 

// SECTION 2 //////////////////////////////////////////////////////////////////

 

// main event loop

 

while(!done)
     {

 

// SECTION 3 //////////////////////////////////////////////////////////////////

 

     // query user for input (the event)

 

     printf("\nWhat's your guess?");
     scanf("%d",&guess);

 

// SECTION 4 //////////////////////////////////////////////////////////////////

 

     // increment number of tries

 

     num_tries++;

 

     // process the event

 

     if (guess > number)
        printf("\nToo big!\n");
     else
     if (guess < number)
        printf("\nToo small!\n");
     else
        {
        // the user must have guessed the number

 

        printf("\nYou guessed the number in %d tries!!!\n",num_tries);

 

        // set the exit flag

 

        done=1;

 

        } // end else

 

     } // end while

 

} // end main

 

 

 

ANY help would be appreciated.

 

Also, someone told me to include the graph.h, but Visual Studio 6.0 doesn't seem to have that. What difference would it make me anyway??
