what is the difference between strcspn() and strpbrk()?

char * strpbrk (char * str1, const char * str2 );

Returns a pointer to the first occurrence in str1 of any of the characters that are part of str2, or a null pointer if there are no matches.

int  strcspn( const char * str1, const char * str2 );

The length of the initial part of str1 not containing any of the characters that are part of str2.

seems both work same , is there any major differences?

These functions are hardly having any application in C++ programming. Well I think so. But still if you want to know about it here is the answer,

In your question strcspn returns a character position whereas strpbrk returns a pointer.

Also by chance if no character is found, strpbrk returns a null pointer; IIRC, under the same circumstances strcspn returns the index of the NUL at the end of the string.

Also I had got a descent explanation about strcspn() and strpbrk(). Check the link.
