编写贷款类loan,如果贷款？

请教C语言编程中计算还贷后剩余的贷款金额的详细答案, 最好能够说明一下每个步骤!

#include stdio.h

int main(void){

    float amount,rate,payment,month_rate,tmp1,tmp2,tmp3;

    printf("Enter amount of lean:");

    scanf("%f",amount);

    printf("Enter interest rate:");

    scanf("%f",rate);

    printf("Enter monthly payment:");

    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("Balance remaining after first payment:%.2f\n",tmp1);

    printf("Balance remaining after second payment:%.2f\n",tmp2);

    printf("Balance remaining after third payment:%.2f\n",tmp3);

}

这是我的答案，我觉得最佳答案对于学习第一章的朋友并不是很友好。

C语言编程题，求解题思路！

只要按照公式计算每月还款金额就可以了,其中"已归还本金累计额"等于"贷款本金 除以 还款月数 乘以 已还款月数".

按照题目要求编写的等额本金还款的C语言程序如下

#includestdio.h

int main(){

double P,R,repayment;

int N,i;

scanf("%lf;%d;%lf",P,N,R);

printf("[");

for(i=0;iN;i++){

repayment=(P/N)+(P-P/N*i)*R;

if(i==N-1)

printf("%.2lf]",repayment);

else

printf("%.2lf,",repayment);

}

return 0;

}

你的错误实在太多了。看代码王的程序简洁易懂

#includestdio.h

#includemath.h

int main()

{

double z,k,x,monthPay,allMoney,temp=0;

int n,i;

printf("输入借款总额、贷款年限、年利率: ");

//贷款总和最好不要用int型的，int的最大值是32767，那你岂不是超了

scanf("%lf%d%lf",z,n,k);

//计算n年后要还的总的钱数 pow(x,y)是在头文件math.h中的函数计算x^y

allMoney = z*pow((1+k/12),12*n);

//式子∑x(1+k/12)^i （i=0,1,2,..,n*12-1）将x提出到前面计算 temp=∑(1+k/12)^i

for(i=0; i12*n; i++)

temp += pow((1+k/12),i);

//根据等式z(1+k/12)^(12*n) = ∑x(1+k/12)^i （i=0,1,2,..,n*12-1） 得x=allMoney/temp;

x = allMoney/temp;

printf("每月应还款：%lf", x);

}
