pow() 函式 - 計算冪次與開根號

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. }
