c++ - 如何标记文件中的值并将其存储在二维数组中

Question

我有一个包含如下内容的文本文件： 1|2|3|4|5|.......23|24|25

我需要阅读这个文件，标记值并将值输入二维数组。

for(i=0; i<size; i++) 
{
    for (j=0; j<size; j++)
    {   
        board[i][j] = *buffer;
        buffer++;
    }
}

我需要使用“|”标记值 作为 delim 并将值输入到二维数组中...请帮助。我知道以上不正确，请帮助。

Answer 1

• Read the data from file in a string.
  

• Apply string tokenizer on your string and get the separate data.

  For tokenizing the string, take a look at Boost.Tokenizer. It's great. Boost generally has some very cool string tools.
  Once you get separate data you can store it in 2-D array.

Answer 2

You could read the whole file into a char * array. I'll assume that's what is in buffer and then use strtok to tokenize with "|".
