Searching for substrings using 'srtchr()'

Question

Using the function strchr is it possible to search for a substring in a string instead of a character?

Example:

Instead of this :

int r=strchr("Hello World",'W');

Can this be used :

int r=strchr("Hello World","World");

Answer 1

Nope. You can use strstr for that

char *substring = strstr("Hello World","World");

Answer 2

Using the function 'strchr()' is it possible to search for a 'substring' in a string instead of a 'character'?

Example :

Instead of this : int r=strchr("Hello World",'W');

Can this be used : int r=strchr("Hello World","World");

No, that's what strstr() is for.

Note also that strchr() does not return int, it returns a char * pointer to the character searched for, or NULL if not found. Compiler warnings exist for a reason...

Answer 3

Use strstr for this.
