Defined in header <cwchar>
const wchar_t* wcsrchr( const wchar_t* str, wchar_t ch );
wchar_t* wcsrchr(       wchar_t* str, wchar_t ch );

Finds the last occurrence of the wide character ch in the wide string pointed to by str.

Parameters

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

Return value

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

Example

Run this code

#include <iostream>
#include <cwchar>
#include <locale>
 
int main()
{
    const wchar_t arr[] = L"白猫 黒猫 кошки";
    const wchar_t* cat = std::wcsrchr(arr, L'猫');
    const wchar_t* dog = std::wcsrchr(arr, L'犬');
 
    std::cout.imbue(std::locale("en_US.utf8"));
 
    if(cat)
        std::cout << "The character 猫 found at position " << cat - arr << '\n';
    else
        std::cout << "The character 猫 not found\n";
 
    if(dog)
        std::cout << "The character 犬 found at position " << dog - arr << '\n';
    else
        std::cout << "The character 犬 not found\n";
}

Output:

The character 猫 found at position 4
The character 犬 not found
