Locate last occurrence of character in string
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.
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 value is not found, the function returns a null pointer.
Portability
In C, this function is declared as:char * strrchr ( const char *, int );
instead of the two overloaded versions provided in C++.
Example
/* strrchr example */ #include <stdio.h> #include <string.h> int main () { char str[] = "This is a sample string"; char * pch; pch=strrchr(str,'s'); printf ("Last occurence of 's' found at %d \n",pch-str+1); return 0; } |
Output:
