strspn("animal", "xyz") = 0
Explanation:
In the first result, l is not in s2.
In the second result, the terminating null is not in s2.
In the third result, a is not in s2 , so the comparison stops.
Search for the first occurrence of a string inside another string.
<string.h>
char *strstr(const char *s1, const char *s2);
s1
s2
Returns the address of the first element that matches the substring if
found; otherwise, returns a null pointer.
This function will find the first occurrence of the string s2 (excluding the
null terminator) within the string s1. If s2 points to a zero length string,
s1 is returned.
