本题要求实现一个计算复数之积的简单函数。
函数接口定义:
struct complex multiply(struct complex x, struct complex y);
其中struct complex
是复数结构体,其定义如下:
struct complex{int real;int imag;
};
裁判测试程序样例:
#include <stdio.h>struct complex{int real;int imag;
};struct complex multiply(struct complex x, struct complex y);int main()
{struct complex product, x, y;scanf("%d%d%d%d", &x.real, &x.imag, &y.real, &y.imag);product = multiply(x, y);printf("(%d+%di) * (%d+%di) = %d + %di\n", x.real, x.imag, y.real, y.imag, product.real, product.imag);return 0;
}/* 你的代码将被嵌在这里 */
输入样例:
3 4 5 6
输出样例:
(3+4i) * (5+6i) = -9 + 38i
代码:
struct complex multiply(struct complex x, struct complex y)
{struct complex a;a.real = x.real * y.real-x.imag*y.imag;a.imag = x.real * y.imag + x.imag * y.real;return a;//返回了一个结构体a
}
