C++指数函数

Question

C++指数函数

Answer 1

math库中有pow(x,y)函数，x为底数，y为指数，返回值为结果，如下：#include <stdlib.h>#include <math.h>#include<iostream>using namespace std;int main() {int x, y, result;cout<<"Enter x,y \n"<<endl;cin>>x>>y;result=pow(x,y);cout<<"\nthe result is:"<<result<<endl;system("pause");return 0;}

Answer 2

#include <iostream>using namespace std;#include "math.h"void main(){int a,b;cin>>a>>b;cout<<pow(a,b)<<endl;}
