c編程方法學答案

Ⅰ 請教C語言編程中計算還貸後剩餘的貸款金額的詳細答案, 最好能夠說明一下每個步驟!

#include<stdio.h>
intmain(void){
floatamount,rate,payment,month_rate,tmp1,tmp2,tmp3;

printf("Enteramountoflean:");
scanf("%f",&amount);

printf("Enterinterestrate:");
scanf("%f",&rate);

printf("Entermonthlypayment:");
scanf("%f",&payment);

month_rate=rate/100.0f/12.0f;
tmp1=(amount-payment)+amount*month_rate;
tmp2=(tmp1-payment)+tmp1*month_rate;
tmp3=(tmp2-payment)+tmp2*month_rate;

printf(":%.2f
",tmp1);
printf(":%.2f
",tmp2);
printf(":%.2f
",tmp3);

}

這是我的答案，我覺得最佳答案對於學習第一章的朋友並不是很友好。
