c++ 快速入门

[html]
#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;
}

输出：

pateo@pateo-B86N53X:~/work/study$ ls
main main.cc
pateo@pateo-B86N53X:~/work/study$ ./main
Enter two numbers:
1
2
The sum of 1 and 2 is 3
pateo@pateo-B86N53X:~/work/study$

[html]
pateo@pateo-B86N53X:~/work/study$ ./main
Enter two numbers:
4 6
The sum of 4 and 6 is 10
pateo@pateo-B86N53X:~/work/study$

endl 说明：操作符，将它写入输出流时，具有输出换行的效果，并刷新与设备相关联的缓冲区，通过刷新缓冲区，用户可立即看到写入到流中的输出

其他说明：c++ 也有前++和后++，相应的for循环等基础语法是一样的

[html]
#include <iostream>
int main()
{
        int sum = 0, value;
    while(std::cin >> value)
        sum += value;
        std::cout << "Sum is " << sum << std::endl;
        return 0;
}

停止动作：两次ctr+d
