用C语言写计算两个复数之和与之积的代码

#include <stdio.h>

struct Complex {
    double real;
    double imag;
};

struct Complex add(struct Complex a, struct Complex b) {
    return (struct Complex){a.real+b.real, a.imag+b.imag};
}

struct Complex multiply(struct Complex a, struct Complex b) {
    return (struct Complex){a.real*b.real-a.imag*b.imag, a.real*b.imag+a.imag*b.real};
}

int main() {
    struct Complex a = {1, 2};
    struct Complex b = {3, 4};
    struct Complex sum = add(a, b);
    struct Complex product = multiply(a, b);
    printf("Sum: %lf + %lfi\n", sum.real, sum.imag);
    printf("Product: %lf + %lfi\n", product.real, product.imag);
    return 0;
}

计算两个复数之和与之积代码c语言

好的，以下是计算两个复数之和与之积的 c 代码：

#include <stdio.h>

typedef struct {
    double real;
    double imag;
} Complex;

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

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;
}

int main() {
    Complex c1 = {1.0, 2.0};
    Complex c2 = {3.0, 4.0};
    Complex sum = add(c1, c2);
    Complex product = multiply(c1, c2);
    printf("Sum: %lf + %lf i\n", sum.real, sum.imag);
    printf("Product: %lf + %lf i\n", product.real, product.imag);
    return 0;
}

C语言用结构体写一个复数之积

可以用结构体表示复数，其中一个成员表示实部，另一个成员表示虚部。乘法运算可以按照复数的乘法规则进行计算。

以下是一个示例代码：

#include <stdio.h>

typedef struct {
    double real;
    double imag;
} Complex;

Complex multiply(Complex a, Complex b) {
    Complex result;
    result.real = a.real * b.real - a.imag * b.imag;
    result.imag = a.real * b.imag + a.imag * b.real;
    return result;
}

int main() {
    Complex a = {1.0, 2.0};
    Complex b = {2.0, 3.0};
    Complex c = multiply(a, b);
    printf("(%g + %gi) * (%g + %gi) = %g + %gi\n", a.real, a.imag, b.real, b.imag, c.real, c.imag);
    return 0;
}

输出结果为：

(1 + 2i) * (2 + 3i) = (-4 + 7i)

其中，`multiply` 函数实现了复数乘法，接受两个复数作为参数，返回它们的乘积。在 `main` 函数中，我们定义了两个复数 `a` 和 `b`，并将它们相乘得到 `c`，最后输出结果。
