Those two are exactly the same. What website says this? PeteBecker Thank you. But, do you have a written evidence?

I think what you are saying is so natural, though. Sure, go to the standard for written evidence. SombreroChicken Almost all of the websites I visited. They are all written in Japanese.

Or at least should be if the compiler in question follows the language at all. But they are not exactly the same. The func2 takes a pointer that is constant, i. Maybe I misunderstood what you said, but gcc reports no errors with this program compiled with "gcc -Wall test. Did I misunderstand what you were saying? Not exact. The are both the same thing only when used as parameters to functions like in main. Either is correct although since I have encountered compilers which generate incorrect code for parameters which are arrays I always code function parameters as pointers when I will be receiving an array.

Art S. Kagel, ka According to my C reference and my understanding of the language, when you specify empty brackets for an array-type variable in an argument list, the compiler handles the variable identically to one explicitly defined as a pointer. Plan: To make Bill Gates suffer Since argc is always one bigger than the highest element of argv, argv[argc] will indeed always work.
