strcpy FUNCTION

Header file statement: #include <string.h>

Syntax: char *strcpy (char *string1, const char *string2);

The strcpy function copies string2, including the terminating null character, to the location

specified by string1, and returns string1.

The strcpy function operates on null-terminated strings. The string arguments to this function

are expected to contain a null character (‘\0’) marking the end of the string. No overflow

checking is performed when strings are copied or appended.

Return Value

The return values for this function are described above.

strcspn FUNCTION

Header file statement: #include <string.h>

Syntax: size_t strcspn (const char *string1, const char *string2);

The strcspn functions return the index of the first character in string1 belonging to the set of

characters specified by string2. This value is equivalent to the length of the initial substring

of string1 consisting entirely of characters not in string2. Terminating null characters are not

considered in the search. If string1 begins with a character from string2, strcspn returns 0.

The strcspn function operates on null-terminated strings. The string arguments to these func-

tions are expected to contain a null character (‘\0’) marking the end of the string.
