我想編寫一個程序來計算變化,但它似乎並沒有工作。 我認爲問題是欠1 /付1;當我試圖在那裏打印值時,我什麼也沒有(0)。 有什麼幫助嗎?C程序來計算變化
#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;
}
解決此類問題的正確工具是您的調試器。在*堆棧溢出問題之前,您應該逐行執行您的代碼。如需更多幫助,請閱讀[如何調試小程序(由Eric Lippert撰寫)](https://ericlippert.com/2014/03/05/how-to-debug-small-programs/)。至少,您應該\編輯您的問題,以包含一個[最小,完整和可驗證](http://stackoverflow.com/help/mcve)示例,該示例再現了您的問題,以及您在調試器。 –
