废话不多说，直接上代码

复制代码 代码如下:

#include <iostream>

using namespace std;

typedef struct

{

double real;

double imag;

} complex;

//复数乘法

complex X_complex(complex a, complex b)

{

complex temp;

temp.real = a.real * b.real - a.imag * b.imag;

temp.imag = b.imag * a.real + a.imag * b.real;

return temp;

}

int main(int argc, char *argv[])

{

complex a,b,c;

a.real = 2;

a.imag = 3;

b.real = 4;

b.imag = 5;

c = X_complex(a,b);//结构体可以作为返回值，然后赋值给另一个相同结构体的变量

cout<<c.real<<","<<c.imag<<endl;

return 0;

}
