C程序设计:复数的结构

typedef struct {
    double real;  // 实部
    double imag;  // 虚部
} Complex;

// 复数加法
Complex add(Complex c1, Complex c2) {
    Complex result;
    result.real = c1.real + c2.real;
    result.imag = c1.imag + c2.imag;
    return result;
}

// 复数乘法
Complex multiply(Complex c1, Complex c2) {
    Complex result;
    result.real = c1.real * c2.real - c1.imag * c2.imag;
    result.imag = c1.real * c2.imag + c1.imag * c2.real;
    return result;
}

// 复数除法
Complex divide(Complex c1, Complex c2) {
    Complex result;
    double denominator = c2.real * c2.real + c2.imag * c2.imag;
    result.real = (c1.real * c2.real + c1.imag * c2.imag) / denominator;
    result.imag = (c1.imag * c2.real - c1.real * c2.imag) / denominator;
    return result;
}
