The wcschr() function is defined in <cwchar> header file.
wcschr() prototype
const wchar_t* wcschr( const wchar_t* str, wchar_t ch ); wchar_t* wcschr( wchar_t* str, wchar_t ch );
The wcschr() function takes two arguments: str and ch. It searches for the wide character ch in the wide string pointed to by str.
wcschr() Parameters
- str: Pointer to the null terminated wide string to be searched for.
- ch: Wide character to search for.
wcschr() Return value
If the wide character ch is found, the wcschr() function returns a pointer to the location of ch in str, otherwise returns null pointer.
Example: How wcschr() function works?
#include <cwchar>
#include <clocale>
#include <iostream>
using namespace std;
int main()
{
setlocale(LC_ALL, "en_US.utf8");
wchar_t str[] = L"\u222b\u222e\u2231\u2211\u220f";
wchar_t ch = L'∫';// Integral sign
if (wcschr(str, ch))
wcout << ch << L" is present \"" << str << L"\"";
else
wcout << ch << L" is not present \"" << str << L"\"";
return 0;
}
When you run the program, the output will be:
∫ is present "∫∮∱∑∏"
