新手問下這道題怎么做啊？編了幾次程序都沒有得到想要的答案。
假如我國國民生產(chǎn)總值的年增長率為7%,計算10年后我國國民生產(chǎn)總值與現(xiàn)在相比增長多少百分比。計算公式為
p=(1+r)^n
r為年增長率，n為年數(shù)，p為與現(xiàn)在相比的倍數(shù)。
以下是代碼語言，不知道是哪里錯了：
#include<stdio.h>
#include<math.h>
int main()
{
?? ?double p,h,n;
?? ?double pow(double x,double y);
?? ?h=1+0.07;
?? ?n=10.0;
?? ?p=pow(h,n);
?? ?printf("%d",p);
?? ?return 0;
}
