好的，我的代碼很長。但是這個有點棘手，所以我只是在這裏裸露。 我什麼程序做是生成隨機數的文本文件，如：結構陣列奇/偶毛刺
123
1234
12345
123456
而且該方案需要在該文件中，並把隨機數據到一個結構數組。 它然後處理數組和輸出，看起來像這樣的文件：
outfile.txt出品基於上述infile.txt：
No Type Odd Even Sum Digit
1234 Even 2 2 10 4
23467 Odd 2 3 22 5
123 Odd 2 1 6 3
但我遇到的問題是，一切都除了我的奇數/偶數停止在其他所有線路上工作之外，我認爲這是正確的和正確的。例如，第一行，它會輸出正確的結果，第二行不會，第三行會再次起作用，依此類推。
//oddcount, evencount. (WORKS, BUT ONLY EVERY OTHER LINE)
int countEven;
int countOdd;
for (int i = 0; i < size; i++)
{
countEven = 0;
countOdd = 0;
while (t[i].no > 0)
{
if (t[i].no % 2 == 1)
{
countOdd++;
t[i].no/= 10;
}
else
{
countEven++;
t[i].no/=10;
}
n[i].oddDigits = countOdd;
n[i].evenDigits = countEven;
} i++;
}
這裏是整個代碼。

傢伙，是的，我知道的代碼是非常非結構化和凌亂尤其是在處理陣列功能 - 我往往會很快，但首先清理了一切，你爲什麼發生這種情況的專業意見，將不勝感激。

我試圖通過codepad.org運行你的代碼，但遺憾的是它沒有文件就無法運行。 –
他舉了一個例子，說明文件的外觀如何; ）然而，我編譯時沒有第二個「i ++」int for循環，結果是正確的...所以威爾伯特的解決方案工作。 – tamasgal
