我想编写一个程序来计算变化,但它似乎并没有工作。 我认为问题是欠1 /付1;当我试图在那里打印值时,我什么也没有(0)。 有什么帮助吗?C程序来计算变化
#include <stdio.h>
int main()
{
double owed, paid;
int dollars, quarters, dimes, nickels, cents, remainder, owed1, paid1;
printf("how much did the customer have to pay ?\n");
scanf("%f",&owed);
printf("how much did the customer pay ?\n");
scanf("%f",&paid);
owed1 = owed * 100;
paid1 = paid * 100;
int change = paid1 - owed1;
dollars = change/100;
remainder = change % 100;
quarters = remainder/25;
remainder = remainder % 25;
dimes = remainder/10;
remainder = remainder % 10;
nickels = remainder/5;
remainder = remainder % 5;
cents = remainder;
printf("%d",dollars);
printf("Dollars:%d, Quarters:%d, Dimes:%d, Nickels:%d, Cents:%d", dollars , quarters , dimes , nickels , cents);
return 0;
}
解决此类问题的正确工具是您的调试器。在*堆栈溢出问题之前,您应该逐行执行您的代码。如需更多帮助,请阅读[如何调试小程序(由Eric Lippert撰写)](https://ericlippert.com/2014/03/05/how-to-debug-small-programs/)。至少,您应该\编辑您的问题,以包含一个[最小,完整和可验证](http://stackoverflow.com/help/mcve)示例,该示例再现了您的问题,以及您在调试器。 –
