童鞋们求解答，这段程序我不知道是哪里出错了，算出的结果不对

#include<stdio.h>

#include<stdlib.h>

#include<math.h>

int main(void)

{

int money,year;

double rate,sum;

printf("Enter money:");

scanf("%d",&money);

printf("Enter year:");

scanf("%d",&year);

printf("Enter rate:");

scanf("%If",&rate);

sum=money*pow(1+rate,year);

printf("sum=%.2f\n",sum);

system("pause");

return 0;

}
