你最好是使用 struct fushu 来定义变量，或者返回的类型。
否则，你最好使用如下的定义：
typedef struct fushu
{
...
}fusht_t;
然后使用 fushu_t 来定义变量等。
1、如果是c语言，必须用struct fusht_t 来定义结构体变量，如果是c++，可以省略struct;
或者这样定义：
typedef struct {
double real;
double i;
}fushu;
2、你的程序有一些不合理的地方，每一次调用函数都会动态申请了一个结构体变量，但都没有释放。
修改如下，供参考：
#include <stdio.h>
#include <stdlib.h>
typedef struct {
double real;
double i;
}fushu;
fushu* add(fushu a, fushu b){
fushu* ret = (fushu*)malloc(sizeof(fushu));
ret->real = a.real + b.real;
ret->i = a.i + b.i;
return ret;
}
fushu* minus(fushu a, fushu b){
fushu* ret = (fushu*)malloc(sizeof(fushu));
ret->real = a.real - b.real;
ret->i = a.i - b.i;
return ret;
}
fushu* multiply(fushu a, fushu b){
fushu* ret = (fushu*)malloc(sizeof(fushu));
ret->real = a.real*b.real - a.i*b.i;
ret->i = a.real*b.i + a.i*b.real;
return ret;
}
fushu* divide(fushu a, fushu b){
fushu* ret = (fushu*)malloc(sizeof(fushu));
ret->real = (a.real*b.real + a.i*b.i)/(b.real*b.real + b.i*b.i);
ret->i = (a.i*b.real - a.real*b.i)/(b.real*b.real + b.i*b.i);
return ret;
}
int main()
{
char sign;
fushu m;
fushu n;
fushu *p=NULL;
scanf("%c%lf%lf%lf%lf",&sign,&m.real,&m.i,&n.real,&n.i);
