Returns a pointer to the last occurrence of character in the C string str.
The terminating null-character is considered part of the C string. Therefore, it can also be located to retrieve a pointer to the end of a string.
If the character is not found, the function returns a null pointer.
instead of the two overloaded versions provided in C++.

strrchr
const char * strrchr ( const char * str, int character ); char * strrchr ( char * str, int character );
Locate last occurrence of character in string
The terminating null-character is considered part of the C string. Therefore, it can also be located to retrieve a pointer to the end of a string.
Parameters
- str
- C string.
- character
- Character to be located. It is passed as its int promotion, but it is internally converted back to char.
Return Value
A pointer to the last occurrence of character in str.If the character is not found, the function returns a null pointer.
Portability
In C, this function is only declared as:char * strrchr ( const char *, int ); instead of the two overloaded versions provided in C++.
Example
|

Output:
Last occurrence of 's' found at 18 |
