Help with pointer arrays please

Hello,

i am doing a module at uni that I need your help with. ( in which I'm building a CPU simulator I am writting for my final year project).

I'm trying to make the simulator accept a file that defines each instruction that the simualotor supports. It has a format specified in the file "intSet.txt". This file detials the exact specification of a given instruction in my program and i was wondering how i could make my program understand the instruciton operation that has been specified by the "RTL" section of the file.

The C program i have attatched is an attempt at reading in each part of the file into various arrays (that would later form part of a structure). unfortunately the 2Dpointer arrays dont seem to work (the early elements of the pointer array seem to get over written) what mistake have i made?

Any help would be great especially in figuring out how to make my program "understand" RTL.

Thanks for your help
Garry

here is the c file:

You're not allocating any memory for your tokenised strings.

Code:

---

        while ((element[q++] = strtok(point_string, search_field)) != NULL)
        {
                point_string = NULL;        /* only needed for the first time */
        //        printf("element[%d] = %s\n", t, element[t]);
        }

---

Should be

Code:

---

char *p;
while ( ( p = strtok(point_string, search_field)) != NULL) {
    element[q] = malloc( strlen(p) + 1 );
    strcpy( element[q], p );
    q++;
    point_string = NULL;
}
