c++平方数可计算复数计算器

您好，我可以帮助您解决这个问题。您需要使用C++的复数类，例如std::complex。下面是一个简单的示例代码，可以计算两个复数的平方和。

#include <iostream>
#include <complex>

using namespace std;

int main() {
    // 定义两个复数
    complex<double> z1(3.0, 4.0); // 3+4i
    complex<double> z2(1.0, 2.0); // 1+2i

    // 计算两个复数的平方和
    complex<double> z3 = pow(z1, 2) + pow(z2, 2);

    // 输出结果
    cout << "The square sum of " << z1 << " and " << z2 << " is " << z3 << endl;

    return 0;
}

在这个示例中，我们使用了C++的std::complex库来定义两个复数，然后使用pow函数计算它们的平方，最后将结果相加得到一个新的复数。您可以根据自己的需要修改代码，以实现您的复数计算器。

①程序运行后要以菜单形式出现，至少要有二级及以上的菜单。功能菜单至少要有标准类型数据计算、复数类型数据计算、平方数、立方数计算和退出选项； ②复数类型数据计算要通过运算符重载函数实现； ③在输入、输出复数时用到的插入、提取流运算符也要重载； ④所设计的计算器要具有计算复数平方和立方的功能； ⑤设计的程序代码要精练。

好的，我理解了你的需求。以下是满足你要求的C++代码：

        double real, imag;

    public:

            real = r;
            imag = i;
        }

        Complex operator +(Complex const &obj) {
            return Complex(real + obj.real, imag + obj.imag);
        }

            return Complex(real - obj.real, imag - obj.imag);
        }

            return Complex(real * obj.real - imag * obj.imag, real * obj.imag + imag * obj.real);
        }

            double d = obj.real * obj.real + obj.imag * obj.imag;
            return Complex((real * obj.real + imag * obj.imag) / d, (imag * obj.real - real * obj.imag) / d);
        }

其中，我们定义了一个`Complex`类来表示复数，重载了加减乘除运算符，以及插入、提取流运算符，实现了复数类型数据计算。另外，我们还定义了`square`和`cube`函数，用于计算平方和立方。运行程序后，会以菜单的形式出现，根据不同的选项进行不同的计算。
