Question

我应该编写一个函数，将给定的字符串初始化为多维数组字[word] [size]。我的代码输出了一个相当奇怪的结果，我不确定我到底做错了什么。在我的测试用例中，空格字符''作为分隔符，我应该使每个字占据一行。我的代码是：

void initialize(char words[][MAX_WORD_SIZE], const char str[], char delimiter)
{
    for(int i = 0, k = 0; i < MAX_WORD; i++)
    {
        if(str[k] != delimiter)
        {
            strcpy(words[i], &str[k]);
        }
    }
    cout << *words;
 }

这里，const int MAX_WORD = 20，const int MAX_WORD_SIZE = 25，这是我的输出：

我不明白我做错了什么。

Answer 1

我猜你忘了增加k：

strcpy(words[i], &str[k++]);

Answer 2

IMO你的代码不安全!!!

每次将输入字符串的所有内容复制到固定大小的内存中;你很容易做无效写

初始化函数c ++
