Question

void sort2(things s[],int n) //商品按人气由高到低排序
{
things t;
for(int i=0;i<n-1;i++)
for(int j=0;j<n-1-i;j++)
if(s[j].popularity<s[j+1].popularity)
{ t=s[j];
s[j]=s[j+1];
s[j+1]=t;
}
}
void sort3(things s[],int a) //商品按评分由高到低排序
{
things t;
for(int i=0;i<a-1;i++)
for(int j=0;j<a-1-i;j++)
if(s[j].grade<s[j+1].grade)
{ t=s[j];

}
}

void information(char n[],int m[],int a,int b) //用户信息录入函数
{
strcpy(link[o1].nam,n);
for(int i=0;i<b;i++)
link[o1].a[i]=m[i];
link[o1].b=0;
link[o1].c.y1=0; //购物车信息录入
link[o1].c.y2=0;
link[o1].c.y3=0;
link[o1].c.y4=0;
}

Answer 1

link[v].v[k1].u = goods[z-1].price;
k1++;
cout << "名称:" << goods[z-1].nam << endl << "价格:" << goods[z-1].price << "亿美元/件" << endl << "数量:" << goods[z-1].numbers << "销量:" //输出想要查看的商品信息
<< goods[z-1].sales_volume << endl << "评分:" << goods[z-1].grade << endl << "人气:" << goods[z-1].popularity << endl << "您是否购买？ Y/N：";
cin >> a1;
goods[z-1].popularity += 1; //浏览该商品后人气值加1
if (a1 == 'N')
goto p3; //跳转到上面
else if (a1 == 'Y') //购买
{
goods[z-1].sales_volume += 1; //销量加1
int s1, s2;
cout << "请输入购买的件数:";
cin >> m;
cout << "1 加入购物车" << endl << "2 结算:";
cin >> s1;
if (s1 == 1) {
link[v].v[k1].y = m;
int h1;
cout << "请您为该商品评分:";
cin >> h1; //为商品评分
goods[z-1].grade = h1;
goto p3; //跳转到上面继续购物
}
} else if (s1 == 2) //结算

Answer 2

应该是括号的问题吧,没有匹配的

追问

我看看
