计算并输出x的n次幂

读入1个正实数x和1个正整数n(n<=50)，计算并输出x的n次幂(保留1位小数)。

#include<stdio.h>
int main(){
    double x,re = 1;
    int n;
    scanf("%lf %d",&x,&n);
    for(int i = 1;i <= n;i++){
        re *= x;
    }
    printf("%.1lf",re);
}

#include<stdio.h>
double power(double x,int n);
main()
{
   double x;
   int n;
   printf("Input x,n:");
   scanf("%lf,%d",&x,&n);
   printf("%.2lf",power(x,n));    
}
double power(double x,int n)
{
   double a=1.0;
   int i;
   for(i=1;i<=n;i++)
   a*=x;
   return a;
