[phylin (神之領域)]

這是我寫的另一種版本
...寫的好像太囉唆點...><

#include <iostream>
#include <cmath>
#include <cstdlib>

using std::cin;
using std::cout;
using std::endl;

int main()
{
int number;
cout << "Please enter how many lines you want to print: " << endl;
cout << "Please enter an odd number: ";
cin >> number;

int Line = 1, Space = 1, Star = 1;

for (Line; Line <= number ; Line++)
   {
    int a = abs((number+1)/2 - Line);
    int b = 2*((number+1)/2 - a)-1;
    for (Space = 1; Space <= a ; Space++)
    cout << " ";
    {for (Star = 1; Star <= b ; Star++)
    cout << "*";
    }
    cout << endl;
    }

  system ("PAUSE");
  return 0;
}

※ 引述《whxu (ㄧㄟㄛ夫～好淫穢)》之銘言：
課本 P167 2.58 --> 印出排列好的星號如下 :
    *
   ***
  *****
 *******

說是越減少程式碼越好......||

#include <iostream>
using namespace std;
int main(void)
{
        int i,j,k=2;
        for(i=1;i>0;i+=k) {
                for(j=0;j<(9-i)/2;j++) cout << " ";
                for(j=0;j<i;j++) cout << "*";
                cout << "\n";
                if(i>7) k=-2;
        }
        return 0;
}

→ yaochia:不是只要列印出給定的星號就好了嗎?
→ phylin:後面那題就要輸入1~19的奇數啊
→ phylin:對了...這個程式是沒有輸入偶數會跳掉的
→ phylin:設計
→ yaochia:喔是喔?...我還沒寫2.59...
→ phylin:所以不是最完美的版本...XD
