s1e9课后作业答疑，求大佬们帮忙
买房题，我写的代码如下：#include<stdio.h>
#include<math.h>
int main()
{
float price,area,yir,mir;//单价、面积、年利率、月利率
float interest,loan;//利息、贷款总额
float ave_repay,down_payment;//月均还款、首期付款
float total_price,total_repay;//房款总额、还款总额
int ratio,time;//按揭成数、按揭年数
printf("请输入单价(元/平方):");
scanf("%f",&price);
printf("请输入面积:");
scanf("%f",&area);
printf("请输入按揭成数：");
scanf("%f",&ratio);
printf("请输入按揭年数：");
scanf("%f",&time);
printf("请输入当前基准年利率：");
scanf("%f",&yir);
mir = yir / 100 / 12;
time = time * 12;
total_price = price * area;
loan = total_price * ratio / 10;
ave_repay = loan * (mir * pow(1+mir,time))/ (pow( 1 + mir,time)-1);
interest = time * ave_repay - loan;
total_repay = loan + interest;
down_payment = total_price * (1- (float)ratio / 10);
printf("====报告结果=====\n");
printf("房款总额:%.2f元\n",total_price);
printf("首期付款:%.2f元\n",down_payment);
printf("贷款总额:%.2f元\n",loan);
printf("还款总额:%.2f元\n",total_repay);
printf("支付利息:%.2f元\n",interest);
printf("月均还款:%.2f元\n",ave_repay);
return 0;
}
运行后的界面：
请输入单价(元/平方):6000
请输入面积:120
请输入按揭成数：7
请输入按揭年数：20
请输入当前基准年利率：5.4
====报告结果=====
房款总额:720000.00元
首期付款:-78366375936000.00元
贷款总额:78366375936000.00元
还款总额:-1.#J元
支付利息:-1.#J元
月均还款:-1.#J元
