首先，你的原来的程序是没什么问题的，问题就在于那个定义，很奇怪，似乎现在的vc的头文件里面不再有那种定义方式，具体原因我也不清楚。所以我这里按照c++的方式重新写了一个。

/* Program 2.17 Working with complex numbers */

#include

#include

#include

using namespace std;

int main(void)

{

complex cx = { 1.0, 3.0 };

complex cy = { 1.0, 4.0 };

//double complex cx = 1.0 + 3.0 * I;

//double complex cy = 1.0 – 4.0 * I;

printf(“Working with complex numbers:”);

printf(“\nStarting values: cx = %.2f%+.2fi cy = %.2f%+.2fi”,real(cx), imag(cx), real(cy), imag(cy));

//double complex sum = cx + cy;

complex sum = cx + cy;

printf(“\n\nThe sum cx + cy = %.2f%+.2fi”,

real(sum), imag(sum));

//double complex difference = cx – cy;

complex difference = cx – cy;

printf(“\n\nThe difference cx – cy = %.2f%+.2fi”, real(difference), imag(difference));

//double complex product = cx*cy;

complex product = cx*cy;

printf(“\n\nThe product cx * cy = %.2f%+.2fi”,

real(product), imag(product));

//double complex quotient = cx / cy;

complex quotient = cx / cy;

printf(“\n\nThe quotient cx / cy = %.2f%+.2fi”,

real(quotient), imag(quotient));

//double complex conjugate = conj(cx);

complex conjugate = conj(cx);

printf(“\n\nThe conjugate of cx = %.2f%+.2fi”,

real(conjugate), imag(conjugate));

return 0;

}
