C語言：計算兩個複數的乘積

複數結構定義如下：

struct Complex
{
	float real;
	float image;
};

計算複數函數原型爲：struct Complex complex_prod(struct Complex c1, struct Complex c2)

在主函數中輸入兩個複數，利用該函數，計算兩個複數的乘積；

代碼如下：

void chapter1::testComplex()
{
	struct Complex c1, c2, result;
	//scanf_s("%f",&c1.real);
	printf_s("請輸入兩個複數");
	scanf_s("%f %f %f %f",&c1.real,&c1.image,&c2.real,&c2.image);
	result = complex_prod(c1, c2);

	printf_s("(%f+%fi)*(%f+%fi) = %f + %fi",c1.real,c1.image,c2.real,c2.image,result.real,result.image);
}

Complex chapter1::complex_prod(Complex c1, Complex c2)
{
	struct Complex temp;
	temp.real = c1.real*c2.real - c1.image*c2.image;
	temp.image = c1.real*c2.image + c1.image *c2.real;
	return temp;
}
