  • 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);
        if( sign == '+' ){
            p=add(m,n);
            printf("%.2lf+%.2lfi\n",p->real,p->i);
        }
        if( sign == '-' ){
            p=minus(m,n);
            printf("%.2lf+%.2lfi\n",p->real,p->i);
        }
        if( sign == '*' ){
            p=multiply(m,n);
            printf("%.2lf+%.2lfi\n",p->real,p->i);
        }
        if( sign == '/' ){
            p=divide(m,n);
            printf("%.2lf+%.2lfi\n",p->real,p->i);
        }
        if(p) delete p;
    
        return 0;
    }
