Thread: std::search isn't working!

Thanks for the reply. I changed my code so it looks like:

Code:

bool ci_equal(char ch1, char ch2)
	{
		return toupper((unsigned char)ch1) == toupper((unsigned char)ch2);
	}
	
	size_t ci_find(const string& str1, const string& str2)
	{
		string::const_iterator pos = search(str1.begin( ), str1.end( ), str2.begin( ), str2.end( ), ci_equal);
		if (pos == str1.end( ))
			return string::npos;
		else
			return pos - str1.begin( );
	}

Now I'm getting the error message:
