c++ 程序

点滴积累，路虽远，行必至！

程序1，将2个结构域值相加，乘以2再加50

#include<iostream>

using namespace std;
int result(int, int);
const int k = 2;
struct point{
    int x, y;
};

int main()
{
    int z(0), b(50);
    point a;
    cout << "请输入2个整数（以空格分割）：";
    cin >> a.x >> a.y;
    z = (a.x + a.y) * k;
    z = result(z, b);
    cout << "输出结果如下：" << endl;
    cout << "(" << a.x << "+"
        << a.y << ")" << "*"
        << k << "+" << b << "=" << z
        << endl;
    return 0;
}
int result(int a, int b)
{
    int c(0);
    c = a + b;
    return c;
}

end!
