C语言数据结构实现银行模拟
实现代码：
#include <stdio.h> #include <stdlib.h> #include <windows.h> #define MAX_WIN 20 #define MAX_STAY 100 typedef struct customer *link; struct customer { int stay; link next; }; link GUY(int stay, link next) { link c = malloc(sizeof *c); c->stay = stay; c->next = next; return c; } link win[MAX_WIN]; void morning() { int i; for(i = 0; i < MAX_WIN; i++) { win[i] = NULL; } } void come(int w, int stay) { if(win[w] == NULL) { win[w] = GUY(stay, NULL); win[w]->next = win[w]; } else win[w] = win[w]->next = GUY(stay, win[w]->next); } void leave(int w) { if(win[w]->next == win[w]) { free(win[w]); win[w] = NULL; } else { link t = win[w]->next; win[w]->next = t->next; free(t); } } void guys() { int i; link t; system("clear"); for(i = 0; i < MAX_WIN; i++, puts(" ")) { printf("WIN%3d:_", i); if((t = win[i]) == NULL) continue; for(; t->next != win[i]; t = t->next) { printf("%4d", t->next->stay); } } Sleep(1); } void later() { int i; for(guys(), i = 0; i < MAX_WIN; i++) { if(win[i] == NULL) continue; if(win[i]->next->stay > 0) (win[i]->next->stay)--; else leave(i); } } int main() { srand(time(NULL)); for(morning; ;later()) { come(rand()%MAX_WIN, rand()%MAX_STAY+1); } return 0; }
由于这里是生成的随机数，所以程序会一直在变化。按住ctrl +c 终止程序
