Write the following function in C.
stripos — Find position of first occurrence of a case-
insensitive string
int stripos ( char* haystack, char* needle, int offset )
Returns the numeric position of the first occurrence of
needle in the haystack string. Note that the needle may be
a string of one or more characters. If needle is not found,
stripos() will return -1.
The function should not make use of any C library function
calls.
