Example:
Explanation:
Each buffer contains the string shown, followed by null characters for a
length of 50. Using strlen will find the length of the string up to but not
including the first null character.
In the first example, 6 characters of buf2 (“Where “) replace the first 6
characters of buf1 ("We're ") and the rest of buf1 remains the same
("here" plus null characters).
In the second example, 18 characters replace the first 18 characters of
buf1 and the rest remain null characters.
In the third example, 5 characters of buf3 ("Why?" plus a null terminat-
ing character) replace the first 5 characters of buf1. buf1 now actually
contains ("Why?", 1 null character, " is the time?", 32 null characters).
strlen shows 4 characters because it stops when it reaches the first
null character.
In the fourth example, since buf4 is only 7 characters strncpy uses 2
additional null characters to replace the first 9 characters of buf1. The
result of buf1 is 6 characters ("Where?") followed by 3 null characters,
followed by 9 characters ("the time?"), followed by 32 null characters.
Search a string for the first occurrence of a character from a specified
set of characters.
<string.h>
char *strpbrk(const char *s1, const char *s2);
s1
s2
Returns a pointer to the matched character in s1 if found; otherwise,
returns a null pointer.
This function will search s1 for the first occurrence of a character
contained in s2.
