C在FOR循环中重置数据计数器

Question

我有一个非常大的文本文件，正在尝试对其进行单词分析。 在字数统计中，我可能也在寻找其他信息，但为简单起见，我将其省略。 在此文本文件中，我使用星号“ *”分隔文本块。 我下面的代码将扫描文本文件，并按需要打印出＃个字符和单词，但是我想在遇到星号后重置计数器，并将所有信息存储在某种形式的表中。 我不太担心如何制作表格，因为我不确定如何在星号之间为每个文本块循环使用相同的计数代码。

也许像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);
          }

由于数组arr []中包含完整的文件文本，因此需要使用*作为分隔符来划分字符串arr 。 您可以使用strtok()使用*作为分隔符来分割该字符串。 然后对每个令牌执行字计数和字符计数操作。 阅读此链接以了解strtok 。
