结构体进行复数的运算

Question

#include <stdio.h>
struct com
{
int real;
int im;
};
main()
{
struct com b1;
struct com b2;
int x,y;
scanf("%d%di",b1.real,b1.im);
scanf("%d%di",b2.real,b2.im);
x = b1.real * b2.real - b1.im * b2.im;
y = b2.real * b1.im + b2.im * b1.real;
printf("%d%+di\n", x,y);
}

段错误，一直运行失败

Answer 1

scanf("%d%di",&b1.real,&b1.im);
scanf("%d%di",&b2.real,&b2.im);
