Hi there,

In the main(int argc, char **argv), what the max. number of command line arguments is?
In my written program, it's no problem if the number is about 200, but the seg. fault occurs if more than 300.
If the number does not matter, what's wrong ?

Help me please...

If there is a maximum number of arguments to a program, it's certainly more than 300 or so.

Segmentation faults occur when you attempt to access memory locations that don't exist. This is commonly caused by using an invalid index into an array.

Use the debugger gdb to help track this down. If that presents too steep a learning curve for now, try simplifying the program as much as possible, and see which simplification step causes the problem to go away.

If you end up with a really simple program which still has the problem, post it here and we can take a look at it.

Hope this helps.
