下面我寫的這個模板妳參考下：
void dispMenu()
{
printf("===========菜單================\n");
printf("==1 功能1==============\n");
printf("==2 功能2==============\n");
printf("==0 退出==============\n");
}
void dispMenu1()
{
printf("===========菜單1================\n");
printf("==1 功能11==============\n");
printf("==2 功能12==============\n");
printf("==0 返回上層菜單==============\n");
}
void func1()
{
int cmd;
dispMenu1();
scanf("%d",&cmd);
while(cmd != 0)
{
if(cmd ==1)
func1();
}
}
void main()
{
int cmd;
dispMenu();
scanf("%d",&cmd);
while(cmd != 0)
{
if(cmd ==1)
func1();
dispMenu();
scanf("%d",&cmd);
}
}
