Arrays question

I was told that C does not put a "null" at the end of an array so one could go on and on before actually finding a "\0" so I was wondering how I might do so using a for loop.

Thanks.

Try this and let us know if it works.

Code:

---


printf("\nArray size %d",n);

---

Then if the array is called "arr"

Code:

---



printf("\nArray last characrer value %c",arr[n-1]);

---

What is that supposed to do and what is "n"?

"n" is the number of character in the array

"If I'm given an array with n number of chars in it."

That assumes that the size is passed in the first place. Just because it's an array of n elements doesn't mean the information exists within the function.

sweet thanks!
