예제 #1

파일: main.cpp 프로젝트: CCJY/coliru

std::basic_istream<e,t>& operator>>(std::basic_istream<e,t>& in, const e& cliteral) {
        e buffer(0);  //get buffer
        in >> buffer; //read data
        if (buffer != cliteral) //if it failed
                in.setstate(in.rdstate() | std::ios::badbit); //set the state
        return in;
}
