wcspbrk() function in C/C++

The wcspbrk() is a built-in function in C/C++ which searches for a set of wide characters present in a wide string in another wide string. It is defined within the cwchar header file of C++. Syntax:

wcspbrk(dest, src)

Parameters: The function has two parameters as shown below.

• dest: It specifies the null terminated wide string to be searched.
• src: It specifies a null terminated wide string containing the characters to search for.

Return Value: The function returns two values as follows:

• If there are one or more than one common wide characters, in dest and src, the function returns the pointer to the first wide character in dest that is also in src.
• If no wide characters is common in src & dest, a null pointer is returned.

Below programs illustrate the above function. Program 1: 

CPP

// C++ program to illustrate the
// wcspbrk() function
#include <cwchar>
#include <iostream>
using namespace std;

int main()
{

    wchar_t src[] = L"Ishwar Gupta";
    wchar_t dest[] = L"GeeksforGeeks";
    wchar_t* s = wcspbrk(dest, src);
    int pos;

    if (s) {
        pos = s - dest;
        wcout << L"First occurrence in \"" << dest
        << L"\" is at position " << pos << endl;
    }
    else
        wcout << L"No number found in \"" << dest << "\"";

    return 0;
}

Output:

First occurrence in "GeeksforGeeks" is at position 0

Program 2: 

CPP

// C++ program to illustrate the
// wcspbrk() function
#include <cwchar>
#include <iostream>
using namespace std;

int main()
{

    wchar_t src[] = L"123";
    wchar_t dest[] = L"Hello World";
    wchar_t* s = wcspbrk(dest, src);
    int pos;

    if (s) {
        pos = s - dest;
        wcout << L"First occurrence in \"" << dest
        << L"\" is at position " << pos << endl;
    }
    else
        wcout << L"No common wide character";

    return 0;
}

Output:

No common wide character
