急！！！求大神砍帮忙编写一道C++的题目，谢谢！！！

你好，可以这样写
double CalculateBudget(double dExpense, int iYears, double dRate)
{
double dTemp = dExpense;
double dRateReal = 1 + dRate * 0.01;
for(int i = 0; i < iYears; i++)
{
dTemp = dTemp * dRateReal;
}

return dTemp;
}

调用部分
int main()
{
double dBudget, dRate;
int iYear;
printf("please input budget:");
scanf("%lf, &dBudget);
printf("please input year:");
scanf("%d, &iYear);
printf("please input inflation rate:");
scanf("%lf, &dRate);

double dResult = CalculateBudget(dBudget, iYear, dRate);
printf("The result is %lf", dResult);

return 0;
}
