문제
매월 특정 대출 금액(이자 포함)에 대해 지불해야 하는 잔액 할부를 계산하는 C 프로그램을 작성하십시오.
해결책
다음은 대출금액이 주어졌을 때 이자를 계산하는 공식입니다 -
i=loanamt * ((interest/100)/12);
다음 계산은 이자가 붙은 금액을 제공합니다 -
i=i+loanamt; firstmon=i-monthlypayment; //first month payment with interest i=firstmon * ((interest/100)/12);으로 첫 달 지불
프로그램
#include<stdio.h>
int main(){
float loanamt,interest,monthlypayment;
float i,firstmon,secondmon;
printf("enter the loan amount:");
scanf("%f",&loanamt);
printf("interest rate:");
scanf("%f",&interest);
printf("monthly payment:");
scanf("%f",&monthlypayment);
//interest calculation//
i=loanamt * ((interest/100)/12);
//amount with interest
i=i+loanamt;
firstmon=i-monthlypayment; //first month payment with interest
i=firstmon * ((interest/100)/12);
i=i+firstmon;
secondmon=i-monthlypayment; //second month payment with interest
printf("remaining amount need to pay after 1st installment:%.2f\n",firstmon);
printf("remaining amount need to pay after 2nd installment:%.2f\n",secondmon);
return 0;
} 출력
enter the loan amount:45000 interest rate:7 monthly payment:1000 remaining amount need to pay after 1st installment:44262.50 remaining amount need to pay after 2nd installment:43520.70
