Answer 2

Answer:

The length of null string is 0.

Explanation:

The method strlen () always returns the length of the provided string byte but not including the null terminator. The strlen just count the elements till it reaches the null character. And it will stop the counting until it reaches null the character. It will not include it with the length.  

It also does not count the character number in arrays. Strlen (const char* ptr) – this will return the string length by counting the ‘non-zero’ until it reaches the zero.
