Answer 1

如果您希望在 if 下执行多个语句，则需要大括号。这是为我编译的修复程序。

#include <iostream>

int main()
{
        std::cout<<"Conversation simulator requires you to type in all caps for all  of your replies"<<std::endl;
        std::cout<<"Type your first and last name!"<<std::endl;
        std::string fname = " ";
        std::string lname = " ";
        bool samename = false;
        std::cin>> fname >> lname;
        if  (fname == "MUSCLE" and lname == "MAN") {
                std::cout<< "Wow, we have the same first and last name!"<<std::endl;
                samename = true;
        } else {
                std::cout<< fname << " "<< lname << "is a very nice name"<<std::endl;
        }
        return 0;
}
