Question

我编写了一个Whatsapp聊天分析器。它是用C语言编写的。首先，我的程序使用fopen（）来打开导出的Whatsapp-chat; ...稍后它应该将临时数组中的Chat成员的名称保存，然后应该写入（如果end_array中的end_array中已经存在相同的名称。否则，该行将被跳过。

检测成员姓名：

- '我的名字'之间的字符：得到保存

问题： End_Array充满了奇怪的字符（见下图）我该如何解决这个问题？在第一行应该只是'andisville'，在第二行Florian Steger ....

Answer 1

您已向后宣布end_arr3：

char end_arr3[nl][members];

其中nl是每个字符串空间的长度，members是字符串的数字。但这为nl字符串留出了空间，每个字符串的长度为members。
