Function to search a string inside of string C

Question

Is there a function to search a string inside of string? For example: String: "Hello". And I want to check if the string "ell" is inside the string "Hello".

[`strstr`](http://en.cppreference.com/w/c/string/byte/strstr) — WhozCraig, May 18 '17 at 16:51
A [good standard string function reference](http://en.cppreference.com/w/c/string/byte) should help. — Some programmer dude, May 18 '17 at 16:52
Ah.. I am probably too late with all ya guys to suggest `strstr`? — Paul Ogilvie, May 18 '17 at 16:53

What about strstr()?

char *strstr(const char *haystack, const char *needle);

for your example, just do the following:

char *ocurrence_str = strstr("Hello", "ell");

Use library strstr() function, which is returns pointer to the first occurrence of the string in a given string.

Read man page of strstr function for more information.

Note: C has no builtin functions! The standard library is not builtin. – too honest for this site May 18 '17 at 17:01
