Thread: Structures and Files

I was wonder if I can make 2 different size structures in a file. I wrote a code but It's apart of my school project and I havent compiled it yet, so Im just wondering will this work?

Code:

if((stsPtr = fopen("status.dat", "rb")) == NULL)
{
    prinft("File could not be created/opened.\n");
    Error();
}
else
{
    fseek(stsPtr, 1 * sizeof(struct avail) SEEK_SET);
        fread(&counts1, sizeof(struct avail), 1, stsPtr);
    for(x = 0; x < 50; x++)
    {
        availSSlot[x] = counts.slot[x];
    }
    int cStudNum = sCount1;
    int cStudNum1 = sCount2;
    int    cStudNum2 = sCount3;
    int cStudNum3 = sCount4;
    int cStudNum4 = sCount5;
    int cStudNum5 = sCount6;
    int cAccNum = aCount;
    fseek(stsPtr, 0 * sizeof(struct stats) SEEK_SET);
    fread(&counts, sizeof(struct stats), 1, stsPtr);
}
fclose(stsPtr);
