Wow! What is MakeString?  Is it a pointer to character?  Does your printf() work
like sprintf()?  how does array get any values in it?  Does MakeString == array?

The strcat() statement causes the contents of string1 to be appended to the
string which starts at the address pointed to by array.

I would expect examining array after each pass, you would see it pointing to
data that looked like this:
" horay!"
" horay! horay!"
" horay! horay! horay!"
" horay! horay! horay! horay!"
...

At some point it's bound to run over some important piece of data.

Based on my guess at what you're trying to do, I think you would want code that
looks like this:

do {
    hours++;

    /* Note: here array is the same as &array[0] */
    printf(array, "Time is: %2U", (hours % 100));
    strcpy(string1, " horay!");
    // trying to use STRCPY.. STRCAT to construct a string
    strcat(array, string1);
    home_lcd();
    puts(array);
    delay_ms(1000);

    /* if the strange printf concatenates, with array, you need
         to make it a null string again */
    array[0] = '\0';

} while(TRUE);

If you're not trying to get practice with strcat and strcpy, this is a better
solution:

do {
    hours++;

    /* Note: here array is the same as &array[0] */
    printf(array, "Time is: %2U horay!", (hours % 100));
    home_lcd();
    puts(array);
    delay_ms(1000);

    /* if the strange printf concatenates, with array, you need
         to make it a null string again */
    array[0] = '\0';

} while(TRUE);
