Question

我的任务是拿一些赢得100万美元累积奖金的人，把它放入银行并以每年8％的利率赚钱。现在，在每年结束之前，他会挣100k。那么多久他需要清空他的账户？

这是我的代码：

#include <stdio.h>
long int year_ended(long int prize);//declare the function to be implemented 


int main(void)

{

    long int jackpot, years;

    jackpot = 1000000;

    for (years = 0; jackpot >= 0; years++) //counting the years until the jackpot is 0
        year_ended(jackpot); 

    printf("it will take %ld years to empty the account", years);

    return 0;
}

long int year_ended(long int prize) //function to decrement 100k every year and add the erned interest

{
    double yearlyRate = 0.08;

    int YearlyWithdraws = 100000, left;

    left = (prize - YearlyWithdraws) * yearlyRate + (prize - YearlyWithdraws);

    prize = left;

    return prize;
}

错误是：程序一直在运行，但我没有输出..

我做错了什么？

Answer 1

for (years = 0; jackpot >= 0; years++)
    year_ended(jackpot);

这是一个无限循环，因为条件始终为真。您可能想要修改jackpot。类似的东西：

for (years = 0; jackpot >= 0; years++) 
    jackpot = year_ended(jackpot);

不能打印出我的功能计算
