不用递归快速求幂（C语言）

#include <stdio.h>
double Pow(double x, unsigned int n)
{
	double temp = 1;
	if(n == 0)
		return 1;
	while(n > 1)
	{
		if(n % 2 == 0)
		{
			x *= x;
			n /= 2;
		}
		else
		{
			temp *= x;
			x *= x;
			n /= 2;
		}
	}
	x *= temp;
	return x;
}
int main()
{
	double x;
	unsigned int n;
	printf("Please enter the base and exponent:\n");
	scanf("%lf %d", &x, &n);
	printf("The answer:%f\n", Pow(x, n))
}
