/*
Scans a string for the first occurence of a given character
Declaration: char *strchr(const char *s, int c);
strchr scans a string in the forward direction, looking for a specific
character. This function finds the first occurrence of the character c
in the string s. The null-terminator is considered to be part of the
string; for example, strchr(strs, 0) returns a pointer to the
terminating null character of the string strs.

 Return Value:
  þ On success, returns a pointer to the
	 first occurrence of the character c in
	 string s.
  þ On error (if c does not occur in s),
	 returns null.
