strchr
Locate character in string
Description
The strchr function locates the first occurrence of c (converted to a char) in the string pointed to by s. The terminating null character is considered part of the string; therefore if c is '\0', the functions locate the terminating '\0'. The strrchr function is identical to strchr except it locates the last occurrence of c.Example:
