C語(yǔ)言中怎么編制簡(jiǎn)單的菜單,通過(guò)菜單選擇能實(shí)現(xiàn)程序的各項(xiàng)功能

求一個(gè)C語(yǔ)言菜單函數(shù)的程序？

1、對(duì)于窗口組件菜單，需要根據(jù)不同平臺(tái)，通過(guò)圖形編程接口，進(jìn)行菜單的編制。

例程：

#includestdio.h?

#includegraphics.h?

#includeconio.h?

void?main()?

{?

char?str;?

int?i,k,choice=1;?

int?gd=DETECT,gm;?

initgraph(gd,gm,"?");?

setbkcolor(2);?

settextstyle(3,0,3);?

outtextxy(140,120,"A.?The?Mock?Clock.");?

outtextxy(140,150,"B.?The?Digital?Clock.");?

outtextxy(140,180,"C.?Exit.");?

setlinestyle(0,0,3);?

rectangle(170,115,370,145);?

/*按上下鍵選擇所需選項(xiàng)*/?

for(i=1;i=100;i++)?

{?

str=getch();?

if(str==72)?

{?

--choice;?

if(choice==0)choice=3;?

}?

if(str==80)?

{?

++choice;?

if(choice==4)choice=1;?

}?

if(str==13)break;?／＊按回車鍵確認(rèn)＊／?

/*畫(huà)圖做菜單*/?

cleardevice();?

switch(choice)?

{?case?1:?setlinestyle(0,0,3);?

rectangle(170,115,400,145);?

settextstyle(3,0,3);?

outtextxy(140,120,"A.?The?Mock?Clock.");?

settextstyle(3,0,3);?

outtextxy(140,150,"B.?The?Digital?Clock.");?

outtextxy(140,180,"C.?Exit.");?

break;?

case?2:?setlinestyle(0,0,3);?

rectangle(170,145,400,175);?

settextstyle(3,0,3);?

outtextxy(140,120,"A.?The?Mock?Clock.");?

settextstyle(3,0,3);?

outtextxy(140,150,"B.?The?Digital?Clock.");?

settextstyle(3,0,3);?

outtextxy(140,180,"C.?Exit.");?

break;?

case?3:?settextstyle(3,0,3);?

outtextxy(140,120,"A.?The?Mock?Clock.");?

outtextxy(140,150,"B.?The?Digital?Clock.");?

settextstyle(3,0,3);?

outtextxy(140,180,"C.?Exit.");?

setlinestyle(0,0,3);?

rectangle(170,175,400,205);?

break;?

}?

}?

if(i=100)exit(0);／＊如果按鍵超過(guò)100次退出＊／?

switch(choice)/*這里引用函數(shù)，實(shí)現(xiàn)所要的功能*/?

{?

case?1:?cleardevice();?

setbkcolor(4);?

settextstyle(3,0,4);?

outtextxy(160,120,"No.1?have?not?built.");?break;?

case?2:?cleardevice();?

setbkcolor(4);?

settextstyle(3,0,4);?

outtextxy(160,150,"No.2?have?not?built.");?

break;?

case?3:?exit(0);?

}?

getch();?

closegraph();?

}

2、對(duì)于命令行菜單，直接通過(guò)不斷刷新輸出來(lái)模擬菜單行為。

例程：

#include?stdio.h

#include?stdlib.h?

#include?string.h

int?n,t,k;

int?m;

char?s1[20],s2[20],c;

char?**l;

char?*num[]={"one","two","three","four","five","six","seven","eight","nine","ten"};

void?menu()

{

printf("\n\n\t\t*******************************************************\n");

printf("\t\t**???1.查找字符串S1中S2出現(xiàn)的次數(shù)????????????????????**\n");

printf("\t\t**???2.統(tǒng)計(jì)字符串中大小寫(xiě)字母，數(shù)字出現(xiàn)的次數(shù)????????**\n");

printf("\t\t**???3.將數(shù)字翻譯成英語(yǔ)??????????????????????????????**\n");

printf("\t\t**???4.結(jié)束??????????????????????????????????????????**\n");

printf("\t\t*******************************************************\n");

printf("\t\t?????您的輸入：");

fflush(stdin);

scanf("%d",n);

}

void?check()

{

char?a[20],b[20];

int?j=0,k,m,l=0;

int?t=0,n=0;

printf("請(qǐng)輸入主字符串：\n");

scanf("%s",a);

k=strlen(a);

printf("請(qǐng)輸入子字符串：\n");

scanf("%s",b);

m=strlen(b);

for(n=0;nk;n++)

if(a[n]==b[0])

{

j++;?/*記錄相同的字符數(shù)*/

do

{????

if(a[++n]==b[++t])

{?

j++;

if(j==m)?

{

l++;/*子字符串相同數(shù)*/

j=0;/*判斷后相同字符數(shù)歸零*/

t=-1;/*判斷中if中++t;t將會(huì)歸零*/

}

}

else

{

j=0;

t=0;

break;/*如果不同跳出while循環(huán)讓for使n+1繼續(xù)判斷*/

}

}while(a[n]!='\0');/*查找完字符數(shù)組a結(jié)束*/

}

printf("子字符串出現(xiàn)次數(shù)：\n%d\n",l);

}??????????????????????????????????

void?cout()

{

int?n=0,t=0,k=0;

printf("請(qǐng)輸入一個(gè)字符串：\n");

fflush(stdin);/*清除緩沖*/

while((c=getchar())!='\n')

{

if(c='a'c='z')

n++;

if(c='A'c='Z')

t++;

if(c='0'c='9')

k++;

}

printf("有大寫(xiě)字母：\n%d\n",t);

printf("有小寫(xiě)字母：\n%d\n",n);

printf("有數(shù)字：\n%d\n",k);

}

void?number()

{

l=num;

printf("請(qǐng)輸入一個(gè)數(shù)字：(0-10)\n");

fflush(stdin);

scanf("%d",m);

printf("%d對(duì)應(yīng)的英文是：\n%s\n",m,*(l+m-1));

}

void?main()

{

while(1)

{???

system("cls");

menu();

switch(n)

{

case?1:system("cls");check();system("pause");break;

case?2:system("cls");cout();system("pause");break;

case?3:system("cls");number();system("pause");break;

case?4:system("cls");break;

default:system("cls");break;?

}

if(n==4)?break;

}

printf("感謝使用\n");

}

在C語(yǔ)言中switch(MenuSelect())是什么意思啊

switch()是C語(yǔ)言中多項(xiàng)選擇功能，

MenuSelect()函數(shù)的返回值表示所選擇的值，然后在switch中去找對(duì)應(yīng)的項(xiàng)，然后執(zhí)行其后續(xù)語(yǔ)句

用c語(yǔ)言制作一個(gè)簡(jiǎn)單的菜單程序，一個(gè)主函數(shù)四個(gè)子函數(shù)

給你一個(gè)簡(jiǎn)單的菜單程序吧。其中的子函數(shù)，填充成樓主所需即可。

#include?stdio.h

/*子函數(shù)1*/

fun1()?{

printf?("子函數(shù)1\n");

}

/*子函數(shù)2*/

fun2()?{

printf?("子函數(shù)2\n");

}

/*子函數(shù)3*/

fun3()?{

printf?("子函數(shù)3\n");

}

/*子函數(shù)4*/

fun4()?{

printf?("子函數(shù)4\n");

}

int?main(void)?{

int?key;?/*命令編號(hào)*/

do?{

system("cls");?/*清屏*/

/*打印菜單*/

printf?("======================================================\n");

printf?("??#\t功能詳情\n");

printf?("------------------------------------------------------\n");

printf?("??1\t功能1\n");

printf?("??2\t功能2\n");

printf?("??3\t功能3\n");

printf?("??4\t功能4\n");

printf?("??5\t退出\n");

printf?("======================================================\n");

printf?("\n");

printf("請(qǐng)輸入命令編號(hào)以開(kāi)啟操作：");

/*輸入命令編號(hào)*/

scanf("%d",key);?

printf?("\n");

/*switch函數(shù)實(shí)現(xiàn)輸入功能序號(hào)執(zhí)行相應(yīng)函數(shù)*/

switch?(key)?{

case?1:?fun1();?break;?/*子函數(shù)1*/

case?2:?fun2();?break;?/*子函數(shù)2*/

case?3:?fun3();?break;?/*子函數(shù)3*/

case?4:?fun4();?break;?/*子函數(shù)4*/

case?5:?printf("程序結(jié)束！按任意鍵退出...\n\n");?break;

default:printf("輸入錯(cuò)誤，請(qǐng)重新輸入！\n\n");?break;

}

/*屏幕暫留*/

if?(key!=5)?{

printf?("\n");

printf("按Enter鍵繼續(xù)...\n");

printf?("\n");

fflush(stdin);

getch?();

}

}?while?(key!=5);

/*屏幕暫留*/

fflush(stdin);

getch?();

return?0;

}
