Question

我有一个非常大的文本文件，我正在尝试进行单词分析。在字数统计中，我可能也在寻找其他信息，但为了简单起见，我把它留了下来。在这个文本文件中，我有用星号'*'分隔的文本块。我下面的代码扫描文本文件并打印出应该填写的字符和单词的数量，但我想在满足星号后重置计数器，并将所有信息存储在某种表格中。我不太担心如何制作表格，因为我不确定如何为星号之间的每个文本块循环相同的计数代码。

也许像

这样的for循环

for (arr = strstr(arr, "*"); arr; arr = strstr(arr + strlen("*"), "*"))

示例文本文件：

=-=-=-=-=-=-=-=-=-=-=-=-=-=-
I have a sentence. I have two sentences now.
*
I have another sentence. And another.
*
I'd like to count the amount of words and characters from the asterisk above this 
one until the next asterkisk, not including the count from the last one.
*
...
    ...
    -=-=-=-=-=-=-=-=-=-=-=-=-=-=-
    (EOF)

Desired output:

    *#      #words     #alphaChar
    ----------------------------
    1        9           34  
    -----------------------------
    2        5           30
    -----------------------------
    3       28           124
    ...
    ...


I have tried

        #include <stdio.h>
        #include <stdlib.h>
        #include <string.h>

        int main()
          {
          int characterCount=0;
          int counterPosition, wordCount=0, alphaCount=0;

          //input file
          FILE *file= fopen("test.txt", "r");
          if (file== NULL)
            printf("Cannot find the file.\n");


          //Count total number of characters in file
          while (1)
              {
              counterPosition = fgetc(speechFile);
              if (counterPosition == EOF)
                break;
              ++characterCount;
              }

          rewind(file); // Sends the pointer to the beginning of the file

          //Dynamically allocate since array size cant be variable
          char *arr= ( char*) malloc(totalCharacterCount);

          while(fscanf(speechFile, "%c", &arr[i]) != EOF ) //Scan until the end of file.
            i++;   //increment, storing each character in a unique position



              for(i = 0; i <characterCount; i++)
                  {
                  if(arr[i] == ' ') //count words
                    wordCount++;

                  if(isalpha(arr[i]))  //count letters only
                    alphaCount++;

                  }//end for loop

              printf("word count is %d and alpha count is %d", wordCount,alphaCount);
          }

由于您在数组arr []中拥有完整文件文本，因此需要使用arr作为分隔符将该字符串*除以。您可以使用strtok()使用*作为分隔符来划分该字符串。然后对每个令牌执行单词计数和字符计数操作。阅读此链接以了解strtok。
