std::strrchr – std::strrchr

Synopsis

Defined in header<cstring>

    const char *strrchr(const char *str, int ch);

char *strrchr(char *str, int ch);

Finds the last occurrence of ch (after conversion to char) in the byte string pointed to by str. The terminating null character is considered to be a part of the string and can be found if searching for ‘\0’.

Parameters

str – pointer to the null-terminated byte string to be analyzed
ch – character to search for

Return value

Pointer to the found character in str, or null pointer if no such character is found.

Example

// Run this code

#include <iostream>

#include <cstring>
int main()

{
    char input[] = "/home/user/hello.c";
    char *output = std::strrchr(input, '/');
    if (output)
        std::cout << output + 1 << '\n';
}

Output:

  hello.c
