四則運算(一)

  1. #include<iostream>  //輸入輸出
  2. #include<cstdlib>   //函式庫
  3. using namespace std;
  4. int main()
  5. {
  6.    
  7.    
  8.    cout << "1+1= " << 1+1 << endl;  //字串 要用""包起來     如果要加上其他輸出的內容   <<
  9.    //"字串" 印出一模一樣的字   
  10.    // 1+1   印出運算的值
  11.    cout << "2-1= " << 2-1 << endl;
  12.    cout << "4*6= " << 4*6 << endl;
  13.    cout << "4/2= " << 4/2 << endl;
  14.    cout << "7除以5的餘數是 " << 7%5 << endl; //取餘數
  15.    //    7/5 =1..2(餘數)
  16.    
  17.    system("pause");
  18.    return 0;
  19. }
