Ⅰ c语言程序
#include<bits/stdc++.h>
using namespace std;
int main()
{
// freopen("ch3_1.in","r",stdin);
// freopen("ch3_1.out","w",stdout);
int sum,m;
cin>>m;
if(0<简清m&&m<100) cout<<早咐链"小礼品一份";
if(m>=100)
{
sum=m/陆孙100;
cout<<sum<<"个10元代金券"<<" "<<"小礼品一份";
}
return 0;
}
Ⅱ 求助，简单的C程序编写 商场购物，每满100元减20元，每满500，再减20，如购物770元，实付
#include<stdio.h>
int main(void)
{
int money;
printf("请输入购物消费金额.\n");
scanf("%d",&money);
int result=0;
result=money-money/100*20-money/500*20;
printf("实际付款金额为：%d",result);
printf("\n");
return 0;
}
这么简单的程序看得懂吧，不需要我说明吧

Ⅳ 【急！】c语言for语句循环结构（求小明应付金额具体如题！！）
/*c语言for语句循环结构（求小明应付金额解答如下！！）*/
#include<stdio.h>
main()/*缺省值*/
{
inta;
烂颤脊floatb[100],sum;/*分配数组*/
printf("购买物品总量: ");
scanf("%d",&a);
for(i=0;i<a;++i)/*for语句的应用*/
{
printf("每个物品的价格：洞带 ");
scanf("%.1f",&b[i]);
sum+=b[i];
}

Ⅳ C语言中模拟超市购物计算价格
我自己设计了一个，你试试！操作结束后按Ctrl+z显示清单。使伍森用方面有什么不懂可以问我！陆念 #include "stdio.h" typedef struct{ char node[100]; /*商品编号*/ char name[100];/*商品名称*/ float price;/*商品价格*/ } datatype; typedef struct node{ datatype food[100]; int len;/*存放商品总数*/ }SPku; datatype Input(void) {datatype x;<br/> scanf("%s %s %f",x.node,x.name,&x.price);<br/> printf("输入完毕！");<br/>return x;<br/>} void create(SPku *r) { int i; printf("\n输入商品总腔悉亩数:"); scanf("%d",&r->len); for(i=0;i<r->len;i++) {printf("\n输入商品编号 名称 价格："); <br/> r->food[i]=Input();<br/>...
Ⅵ c语言编程超市促销，满200送40，键盘输入客户购买总金额，屏幕输出返送的金额数
#include<stdio.h>
void main()
{
int money,back=0;
printf("请输入客户购买慧知总金扮碧亏额:\n");
scanf("%d",&money);
if(money>0)
back=money/200*40;
printf("厅神返送的金额数为：%d\n",back);
}
Ⅶ c语言 如何用switch语句编写一个有关商场购物金额优惠的选择程序
#include <stdio.h>
int main(int argc, char** argv)
{
int amount = 0;
scanf("%d", &amount);//输入顾客购买的总额
int status = amount/1000;
switch (status)
{
case 0: break;
case 1: amount = amount * 0.95; break;
case 2: amount = amount*0.90; break;
case 3: amount *= 0.85; break;
default: amount *= 0.80; break;
}
printf("%d\n", amount);//打印出打折后的总额
return 0;
}
