标题: 菜鸟请教问题 iostream报错？
我初学照着书写下列程序
#include <iostream>
int main()
{
      std::cout << "Enter two numbers:" <<std::endl;
      int v1,v2;
      std::cin >> v1 >>v2;
      std::cout << "The sum of " << v1 << " and " << v2 << " is " << v1 + v2 << std::endl;
      return 0;
}

然后编译
cc program_1.2.1.cc
结果系统出了一堆东西。。。

如下

请教大侠们  是怎么回事？程序和书上的一样的啊。。。无奈中。。。
谢谢！

我初学照着书写下列程序
#include
int main()
{
std::cout >v2;
std::cout

cc program_1.2.1.cc 改成 g++ program_1.2.1.cc
