为什么';当我按0时,我的程序不会停止吗?C程序
我做了一个简单的程序,问你是否可以进入一个酒吧,如果你的年龄。然后问你愿意花多少钱,然后问你第一次买多少钱。它继续询问您是否想购买更多,但是如果我不想购买更多,我可以输入值“0”,但当我输入“0”时,它不会关闭程序 代码如下:为什么';当我按0时,我的程序不会停止吗?C程序,c,C,我做了一个简单的程序,问你是否可以进入一个酒吧,如果你的年龄。然后问你愿意花多少钱,然后问你第一次买多少钱。它继续询问您是否想购买更多,但是如果我不想购买更多,我可以输入值“0”,但当我输入“0”时,它不会关闭程序 代码如下: #include <stdio.h> int main() { int age, legal = 18; float money, buy; printf("At the bar the security must ID the customers

#包括
int main(){

流动资金,购买;
printf(“在酒吧,保安必须识别看起来未成年的顾客,你的年龄是多少?:”;
scanf(“%d”和年龄);
如果(年龄<法定年龄){
printf(“\n不允许您!\n”);
}
否则,如果(年龄>=法定年龄){
printf(“\n您可以输入并购买您想要的任何东西!\n”);
printf(“\n您今晚愿意花多少钱?:”;
scanf(“%f”和money);
printf(“\n连同你今晚想花的%.2f美元,你想先买的食物或饮料的价格是多少?:”,money);
scanf(“%f”、&buy);
金钱=金钱购买;
而(货币>0 | |购买==0){
printf(“\n您现在还有%.2f美元,您还想买什么?(如果您不想再买,请按0停止!!):”,money);
scanf(“%f”、&buy);
金钱=金钱购买;
}
如果(货币==0){
printf(“\n您已经花光了所有希望在酒吧消费的钱,希望您在这里过得愉快!!\n”);
}
如果(钱>0)则为else{
printf(“\n您还有%.2f美元,希望您在酒吧过得愉快!!\n”);
}
}
}
您的while循环错误。它说,当钱不是零,或者当购买是零时,询问消费金额
它应该说
while(money!=0&&buy>0)
这样,只要他们有钱并且正在消费(buy高于零),它就会询问消费金额。请避免使用float
或double
来表示金钱,因为它们给出了不精确的比较。使用int
以美分计算,并将输出格式设置为美元.cents。拆分
上的任何输入字符串以将其转换为美分。
