Only if it's a static variable. If it is a normal automatic variable, no default initialisation exists. In that case you do need the null character if you intend to use the value before assigning to it. -- \| Kingpriest of "The Flying Lemon Tree" G++ FR FW+ M- #108 D+ ADA N+++\| \| http://www.helsinki.fi/~palaste W++ B OP+ \| \----------------------------------------- Finland rules! ------------/ "This is a personnel commuter." - Train driver in Scientific American

Only if it's "global" (or rather, has file scope) or it's an object of static storage. For local variables, this initialisation is correct. (Assuming you want an array of '\0' characters.) If this array is for a string, you might get away with just assigning the first element. It's up to you. Bill, 'ip 'ip,
