Will it not count the NULL in the string ?

I perceive that strlen() function is defined in c library in such a way that null is not counted unless it is mentioned specifically as '\0' at the end during the string declaration.

It's not null. It's nul character '\0'-Ascii value is 0 (1 byte) it excluding in string length as well nul character including in string size.
NULL is related to pointer its 4 byte.

#include<stdio.h>
#include<string.h>
int main()
{
char s[20]={'1','2','3','4','5','\0'};
int len=strlen(s);
printf("%d",len);
}
Here, even the output will be 5. In the string, null is not counted!
