大神们！这个程序在没有错误，能运行，为什么一到蓝桥杯提交时间就会显示编译错误的？

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; }2019-07-17 19:12:04赞同 展开评论 打赏
