strlen interprets the string as a single-byte character string, so its return value is always equal to the number of bytes, even if the string contains multibyte characters wcslen is a wide-character version of strlen; the argument of wcslen is a wide-character string and the count of characters is in wide (two-byte) characters wcslen and
- strlen - C++ Users
defines an array of characters with a size of 100 char s, but the C string with which mystr has been initialized has a length of only 11 characters Therefore, while sizeof (mystr) evaluates to 100, strlen (mystr) returns 11 In C++, char_traits::length implements the same behavior C string The length of string char szInput[256];
