    No it isn't. It is NULL, or a zero value, used commonly to denote the end of a string.

    Use fgets or scanf with the appropriate arguments.

    I'll assume that you mean "end" as in: the first unused cell in an array.

    You can use strlen to find the length, or you can just loop through the array looking for NULL.

    Hope is the first step on the road to disappointment.

    Thumbs up end of an array...

    hello dking,
    u can use the 'sizeof()' operator to know the length or size of your array variable.
    i'm using Turbo C and its compiler.
    thanx...
    take care...
