字符数组复制错误

Question

我的问题是，当内部for循环退出并返回外部for循环时，它会停止向字符串指针pstrDestination添加字符。有人可以向我解释一下，我不会终止字符数组，所以它仍然应该写，不应该吗？

// Does it match
if (strcmp(strCompareString, pstrToFind) == 0)
{

    // Reset the index of the found letter
    intFoundLetterIndex = (intFoundLetterIndex - intCompareIndex);

    // Add the characters from source to destination.
    for (intSourceIndex = 0; intSourceIndex < intSourceLength; intSourceIndex += 1)
    {

        pstrDestination[intDestinationIndex] = pstrSource[intSourceIndex];
        intDestinationIndex += 1;

        // Are we at the beginning of the target word
        if (intSourceIndex == intFoundLetterIndex)
        {

            // Add the replacement characters to the destination.
            for (intNewIndex = 0; intNewIndex < intReplaceWithLength; intNewIndex += 1)
            {

                pstrDestination[intDestinationIndex - 1] = pstrReplaceWith[intNewIndex];
                intDestinationIndex += 1;

            }

            intSourceIndex += intToFindLength;
        }

    }

}

我想这个

intDestinationIndex - 1;

应如下所示：

intDestinationIndex -= 1;
