C++ C++；使用库的应用程序表示未检测到成员

所以，我有一个应用程序，在DOS选择一个数字样式中使用一组数学公式。所以我制作了一个静态库，目前我已经链接了它们，但是当我尝试使用一个函数时，它会说没有检测到成员。以下是我的代码（重要部分）： //库头文件：

namespace Library_ {
static float min, max, n, rem, i, r, l, w, m, v, k, r1, r2, r3, r4, h, b,
       b1, b2, s, value, count = 0; static float f = 1;

static class Main
{
public:
    class Geometry_2Dimensional
    {
        static void rectangle();
        static void circle();
        static void ETGRadius();
        static void ETGSide();
    };

    class Geometry_3Dimensional
    {
        static void prismRectangle();
        static void prismTriangle();
        static void cylinder();

    };

    class Computing

        static void factorial();

cout您在这里犯了太多错误，很难知道从哪里开始，像使用名称空间一样使用类，使用全局变量，在库代码中进行输入和输出，不使用函数参数和函数返回，不适当地使用static等等。此外，由于您没有显示trong>如何调用函数

我可以回答一个问题，“何时使用静态”。根据您的经验，答案是永远不要使用静态。您必须先学习基本知识

忘记类。忘记名称空间，忘记全局变量，首先学习如何编写函数，如何使用局部变量，如何向函数传递值和从函数返回值

例如，以下是完全可以接受的初学者代码

void Geometry_2Dimensional_ETGRadius(float r1, float r2, float& n, float& k)
{
    float r3 = sqrt(r2);
    float m = (sqrt(3) / 3);
    if (r2 == 3)
    {
        n = r1 * 3;
        float v = n / 2;
        k = sqrt((n * n) - (v * v));
    }
    else
    {
        float r4 = r3 * r1;
        n = r4 / m;
        float v = n / 2;
        k = sqrt((n*n) - (v*v));
    }
}

int main()
{
    float r1, r2, n, k;
    cout << "Integer part: "; cin >> r1;
    cout << "Radicant: "; cin >> r2;
    Geometry_2Dimensional_ETGRadius(r1, r2, n, k);
    cout << "The side length of the triangle is: " << n << endl;
    cout << "The area of the triangle is: " << (k * n) / 2 << endl;
    system("PAUSE");
}

void Geometry\u 2Dimensional\u ETGRadius（浮点r1、浮点r2、浮点n、浮点k）
{
浮点数r3=sqrt（r2）；
浮动m=（sqrt（3）/3）；
如果（r2==3）
{
n=r1*3；
浮点数v=n/2；
k=sqrt（（n*n）-（v*v））；
}
其他的
{
浮点数r4=r3*r1；
n=r4/m；
浮点数v=n/2；
k=sqrt（（n*n）-（v*v））；
}
}
int main（）
{

你能不能包括你的main.cpp文件和链接器标志以及…？@paykoob链接器标志，这意味着所有的包含和使用？我正在使用stdafx.h，所以这里有所有的内容：#包括“targetver.h”#包括“Library\CalculatorLib.h”#包括使用namespace std；使用namespace Library#；但是我想要创建一个库的全部原因是，我的主应用程序需要更少的代码，因为所有函数和变量都在库中，我的主函数只关注在控制台应用程序中导航和使用函数。这些函数不会然后在流式处理中处理这些变量，因此类似于案例1:Main:：Geometry_2Dimensional:：rectangle（）；但当我做Main:：Geometry_2Dimensional:：时，它说不包括任何成员，你可以将普通函数放入库中。你不需要名称空间或类来创建库。你试图一次做太多事情，却不了解你想做什么。你试图编写的代码即使对于有经验的程序来说也不是好代码rammer。你必须先学习基础知识。我知道有更简单的方法可以做到这一点，它只是一种编码OCD，一切都必须组织起来。
