C控制台菜单

前几天看某个作业贴,有个要求是菜单必须能用光标选择,一时无事,就把这个功能给做了,算是给各位写作业的同学锦上添花吧

a.h
[quote]
#include <stdio.h>
#include <conio.h>
#include <stdlib.h>

#define DefaultWidth 50
typedef void (*MenuFun)(void);
struct _Menu;
typedef struct _Selection
{
  char MenuInfor[100];
  MenuFun fun;
  _Menu* SubMenu;
}Selection, *PSelection;
typedef struct _Menu
{
  PSelection SelectionArray;
  int nSelectionCount;
}Menu, *PMenu;

void PrintSame(char c, int n)
{
  int i;
  for (i = 0; i < n; i++)
  {
printf("%c", c);
  }
}

void ShowMenu(PMenu m,int select, int width)
{
  int i, l = m->nSelectionCount;
  width = width < DefaultWidth ? DefaultWidth : width;
  system("cls");
  PrintSame('*', width);
  printf("\n");
  for (i = 0; i < l; i++)
  {
if (i == select)
   printf("**  ==> ");
else
   printf("**    ");
printf("%-*s**\n", width - 10, m->SelectionArray[i].MenuInfor);
  }
  PrintSame('*', width);
  printf("\n");
  printf("数字键:直接选择  方向键:移动光标  回车:确定  ESC:取消\n");
}

void DynamicMenu(PMenu m, int width)
{
  char c = 0;
  int select = 0, l = m->nSelectionCount;
  while (c != 27)
  {
ShowMenu(m, select, width);
c = getch();
if (c == -32)
{
   c = getch();
   if (c == 72 && select > 0)
      select--;
   else if (c == 80 && select < l - 1)
      select++;
}
else if (c == 13)
   if (m->SelectionArray[select].SubMenu == NULL)
      m->SelectionArray[select].fun();
   else
      DynamicMenu(m->SelectionArray[select].SubMenu, width);
else if (c >= 1 + '0' && c <= m->nSelectionCount + '0')
   if (m->SelectionArray[c - '1'].SubMenu == NULL)
      m->SelectionArray[c - '1'].fun();
   else
      DynamicMenu(m->SelectionArray[c - '1'].SubMenu, width);
  }
}[/quote]

下面的a.cpp是演示如何使用
[quote]
#include "a.h"

#define p(x)\
  printf("%s 被调用\n按任意键继续..", x);\
  getch()

void f1()
{
  p("f1");
}

void f2()
{
  p("f2");
}

void f3()
{
  p("f3");
}

void f4()
{
  p("f4");
}

int main()
{
  char c = 0;
  Selection s1[4] = {"1.子菜单11", f1, NULL, "2.子菜单12", f2, NULL, "3.子菜单13", f3, NULL, "4.子菜单14", f4, NULL};
  Selection s3[2] = {"1.子菜单31", f1, NULL, "2.子菜单32", f2, NULL};
  Menu m1 = {s1, 4};
  Menu m3 = {s3, 2};
  Selection s[3] = {"1.菜单1..", f1, &m1, "2.菜单2", f2, NULL, "3.菜单3..", f3, &m3};
  Menu m = {s, 3};
  DynamicMenu(&m, 60);
  return 0;
}[/quote]

以上程序WinXP(SP2)+VC6测试通过

顺便为了照顾不得不使用TC的同学,特别修改了一个TC版,TC2测试通过

附件中包含VC和TC两种版本

没人提点意见建议?

我试试看,不过好像有不少可以省略的标签哦,难道我下的这个不是最新版的?

楼主
下了
学习~~
大概的看了一下
果然我是菜鸟
水平就是不够
要写出这个水平还得有一定时间
