餐饮点餐系统（2）

今天我们继续完成我们的项目，本次的目标是为每一个分支选项，创建菜单。

分析：1.首先我们要为每一个分支选项创建一个函数

2.其次是调用我们创建的函数

3.最后创建的自定义函数中会用到，while语句，switch语句，在之前的分享中既有这知识点，感兴趣的可以去看看。

运行代码：

#include<stdio.h>//头文件
int record[];//记录，记录价格
void pastries_menu()//面点——菜单
{while (1){int a = 0;printf("欢欢面点菜单\n");printf("1.麻辣排骨面-10元\n");printf("2.阳春面-6元\n");printf("3.炸酱面-8元\n");printf("4.牛肉面-8元\n");printf("5.刀削面-10元\n");printf("6.羊肉泡馍-18元\n");printf("0.点餐结束\n");printf("请选择您想要的面点：");scanf("%d", &a);switch (a){case 1:printf("麻辣排骨面-10元\n");break;case 2:printf("阳春面-6元\n");break; case 3:printf("炸酱面-8元\n");break; case 4:printf("牛肉面-8元\n");break; case 5:printf("刀削面-10元\n");break;case 6:printf("羊肉泡馍-18元\n");break;case 0:printf("感谢您的光临！\n");return 0;default:printf("抱歉没有这项选项！\n");break;}}}void rice_with_toppings_menu()//盖饭菜单
{while (1){int b= 0;printf("欢欢盖饭菜单\n");printf("1.东北大米盖饭-1元\n");printf("2.小炒黄牛肉盖饭-12元\n");printf("3.辣子鸡盖饭-10元\n");printf("4.泡椒肉丝盖饭-10元\n");printf("5.麻辣排骨盖饭-12元\n");printf("6.肉沫茄子盖饭-10元\n");printf("7.酸菜肉丝盖饭-10元\n");printf("0.点餐结束\n");printf("请选择您想要的盖饭：");scanf("%d", &b);switch (b){case 1:printf("东北大米盖饭-1元\n");break;case 2:printf("小炒黄牛肉盖饭-12元\n");break;case 3:printf("辣子鸡盖饭-10元\n");break;case 4:printf("泡椒肉丝盖饭-10元\n");break;case 5:printf("麻辣排骨盖饭-12元\n");break;case 6:printf("肉沫茄子盖饭-10元\n");break;case 7:printf("酸菜肉丝盖饭-10元\n");break;case 0:printf("感谢您的光临！\n");return 0;default:printf("抱歉没有这项选项！\n");break;}}}void special_stir_fried_dish_menu()//小炒菜单

}void soup_menu()//汤类菜单
{while (1){int e = 0;printf("欢欢汤类菜单\n");printf("1.西红柿鸡蛋汤-6元\n");printf("2.红枣乌鸡汤-12元\n");printf("3.酸菜粉丝汤-6元\n");printf("4.豇豆老鸭汤-12元\n");printf("5.鸭血白菜汤-8元\n");printf("0.点餐结束\n");printf("请选择您想要的汤类：");scanf("%d", &e);switch (e){case 1:printf("西红柿鸡蛋汤-6元\n");break;case 2:printf("红枣乌鸡汤-12元\n");break;case 3:printf("酸菜粉丝汤-6元\n");break;case 4:printf("豇豆老鸭汤-12元\n");break;case 5:printf("鸭血白菜汤-8元\n");break;case 0:printf("感谢您的光临！\n");return 0;default:printf("抱歉没有这项选项！\n");break;}}
}void drink_menu()//饮品菜单
{while (1){int f = 0;printf("欢欢饮品菜单\n");printf("1.橙汁-3元\n");printf("2.可乐-3元\n");printf("3.雪碧-3元\n");printf("4.纯牛奶-3元\n");printf("5.王老吉-3元\n");printf("6.冰糖雪梨-3元\n");printf("0.点餐结束\n");printf("请选择您想要的饮品：");scanf("%d", &f);switch (f){case 1:printf("橙汁-3元\n");break;case 2:printf("可乐-3元\n");break;case 3:printf("雪碧-3元\n");break;case 4:printf("纯牛奶-3元\n");break;case 5:printf("王老吉-3元\n");break;case 6:printf("冰糖雪梨-3元\n");break;case 0:printf("感谢您的光临！\n");return 0;default:printf("抱歉没有这项选项！\n");break;}}
}
int main()//主函数

}

运行结果：
