我有一个名为example.cpp的cpp程序。在这个程序中，我想逐行读取stdin并将每一行保存在一个字符串中。但它不是来自关键字或文件。输入来自命令行：
CC example.cpp -o ALO
last -n 10 | ./ALO
我尝试了以下几种方法但不适用于此：
for (std::string line; std::getline(std::cin, line);) {
std::cout << line << std::endl;
}
return 0;
或
char name[256];
while (cin.getline (name,256))
{
cout << "Got " << name << endl;
}
或
string name;
while (getline(cin, name))
{
cout << "Got " << name << endl;
}
