pow() 函式 - 計算冪次與開根號

方浩葦

利用pow() 函式, 設計一個可以輕鬆計算冪次與開根號的計算機.

1. #include<iostream>
   
2. #include<cstdlib>
   
3. #include<cmath>
   
4. using namespace std;
   
5. int main()
   
6. {
   
7.     double x, y;
   
8.     cout<<"請輸入底數: ";
   
9.     cin>>x;
   
10.     cout<<"請輸入指數: ";
    
11.     cin>>y;
    
12.     cout<<x<<"的"<<y<<"次方,值為"<<pow(x,y)<<endl;
    
13.     system("pause");
    
14.     return 0;   
    
15. }
