VC++6.0 错误提示：.exe已停止工作

[hu_huiqin]

我的一段C代码如下：

#include <stdio.h>
#include <math.h>

int main(void){
double amount;
double principal =1000.0;
double rate=.05;
int year;

printf("%4s%21s\n","Year","Amount on deposit");

for(year = 1;year <= 10;year++){

amount = principal * pow(1.0+rate,year);

printf("%4s%21.2f\n",year,amount);
}

return 0;
}

编译通过，运行时出现如图所示错误，求大侠讲解。
amount.exe已停止工作。

printf("%4s%21.2f\n",year,amount);
改为

printf("%4d%21.2f\n",year,amount);

[Linkhai]

注意输出格式，要用%4d

[qiaowei0]

printf("%4s%21.2f\n",year,amount);
不对！
