Even though it's looks like this is the solution

is there any reason for not doing it this way:

    printf("\nBinary: ");
    for(counter=(sizeof(int)*8);counter>=0;--counter)
    {
        temp = 1 << (counter);
        printf("%d", (number & temp) ? 1 : 0);
    }

What is (1 << (sizeof(int)*8)) supposed to be?
^^^^^^^^^^^^^
gives the number of bits in an int and left-shifts 1 that number of times.

I suppose that I should have used:

for(counter=(sizeof(int)*CHAR_BIT);counter>=0;--counter)
^^^^^^^^^
However, I'm guessing that you missed the above, which would mean that mean you missed that for the first run through the loop:

temp = 1 << (counter);

would be the equivalent of:

temp = 1 << ((sizeof(int)*8)-1)
