1、C语言课程设计案例--菜单设计调试环境为TC2.0或者3.0。运行这个程序需要tc提供的几个头文件。建议修改options菜单中的include目录项到tc的include的目录下(具体方法可以参见本书第一章的讲解)；或者把源程序拷贝到tc目录下运行。#include#include#include#include#include/*定义一些常数*/#defineNO0#defineYES1#defineNONE-1#defineMAX_MENU7/*根据情况改变可以在

2、菜单显示的最大项*//*全局参数*/intX,Y;intSelection;intbutton,x,y;void*p;size_tarea;/*菜单结构*/structMENU{/*左上角*/intx;inty;/*右下角*/intx1;inty1;unsignedcharActive[MAX_MENU];/*菜单项是否激活的标志*/char*head;/*菜单的名字（可选项）*/};intMouseOn(structMENU*t);voidProcess();voidXorbar(intsx,intsy,intex,intey,intc);voidShow()

3、;voidHide();voidStatus();/*通过下面的参数用户可以改变按钮的位置。*/structMENUFile={200,110,250,130};structMENUEdit={295,110,345,130};structMENUHelp={390,110,440,130};structMENUClose={600,10,620,30};structMENUNeeraj={380,300,460,315};voidmain(){intgd=DETECT,gm;/*初始化图形界面*/initgraph(&gd,&gm,"");Selection=
