clearing array elements?
I have a character array:
test[10]; slots 0-9 are filled in the array..I want to clear the array so brand new character can be entered in there place. How would I go about doing this? -andy

Two ways immediately come to mind.
To write over all the elements of the array with a NULL (value of zero), you could either use a loop or use memset: Code:
memset(test, 0, 10); Or, if you just want to make it an empty string: Code:
test[0] = '\0'; In this second case, it doesn't matter that the previous characters are still in the array, because the string ends at the NULL.

third: just enter the new char's in the array. They don't mind if there's a '\0' there or some other char.
