第一节 练习26

#include<iostream>
#include<iomanip>
#include<cstdio>
#include<cmath>
#include<algorithm>

using namespace std;

int main()
{
	int a,b;
	long long c; 
	cout << "输入：";
	cin >> a >> b; 
	
	c = (long long)pow(a,b) % 1000;  //pow返回double！！！太精确了啊 
	//在强转面前，不堪一击 
	//printf("%03lld",c);  //long long配合%lld 
	cout << c;
	return 0;
}
//cout << "输入：";

结果：
