閱讀和格式化文本文件在ansi c

Question

我正在學習C和它在文本文件中讀取的任務之一，並讓它輸出格式化的文本文件。最終的產品應該是這樣的：

1)"I must not fear.[4,17] 
2)Fear is the mind-killer.[4,24] 
3)Fear is the little-death that brings total obliteration.[8,56] 
4)I will face my fear.[5,20] 
. 
. 
. 
13)oneWord_allAlone[1,16] 
13 lines, 94 words, 481 characters 
Line 10 has the most words (16) 
Line 7 has the most characters (68) 

我寫的代碼，並可以得到一些接近十歲上下，但信息是出的秩序和變量是錯誤的，它切斷各自的第一個字母句子。我得到：

I must not fear0.) 
[4, 16] 
ear is the mind-killer.0) 
[7 39] 
ear is the little-death that brings total obliteration.0) 
[14 92] 
. 
. 
. 
neWord_allAlone1) 
[86 470] 
1 lines, 20360 words, 110685 characters 
line 1 has the most words with (86) 
line 1 has the most characters with 470)  

它在哪裏得到110685個字符超出了我。所以，就這樣說，我做錯了什麼？據我所知，我有所有的變量設置正確，但輸出的順序是錯誤的，第一個字符被切斷，並計數是有點兒關閉。任何幫助深表感謝！這裏是我的代碼：

#include <stdio.h> 

#define IN 1 
#define OUT 0 

void main() { 

    int c = 0; 
    int numChars = 0; 
    int numWords = 0; 
    int numLines = 0; 
    int state = OUT; 
    int test = 0; 
    int largestNumChars = 0; 
    int largestNumWords = 0; 
    int totalNumChars = 0; 
    int totalNumWords = 0; 
    int lineWithMostChars = 0; 
    int lineWithMostWords = 0; 

    FILE *doesthiswork = fopen("testWords.in", "r"); 
    while ((test = fgetc(doesthiswork)) != EOF) { 
    if (test == '\n') { 
      ++numLines; 
    } 
    while ((test = fgetc(doesthiswork)) != '\n') {  
     ++numChars; 
     putchar(test); 
     if (test == ' ' || test == '\t' || test == '\n') {  
      state = OUT; 
     } else if (state == OUT){ 
      state = IN; 
      ++numWords;   
     } 
     totalNumWords = totalNumWords + numWords; 
     totalNumChars = totalNumChars + numChars;  
    } 

    if (largestNumChars == 0) { 
     largestNumChars = numChars; 
    } else if (largestNumChars < numChars) { 
     largestNumChars = numChars; 
     lineWithMostChars = numLines; 
    } else { 
     largestNumChars = largestNumChars; 
     lineWithMostChars = lineWithMostChars; 
    } 

    if (largestNumWords == 0) { 
     largestNumWords = numWords; 
     lineWithMostWords = numLines; 
    } else if (largestNumWords < numWords) { 
     largestNumWords = numWords; 
     lineWithMostWords = lineWithMostWords; 
    } else { 
     largestNumWords = largestNumWords; 
    } 

    printf("%d) %c [%d %d]\n",numLines, test, numWords, numChars); 
    } 

    printf("%d lines, %d words, %d characters\n", 
    numLines, totalNumWords, totalNumChars); 
    printf("line %d has the most words with (%d)\n", 
    lineWithMostWords, largestNumWords); 
    printf("line %d has the most characters with (%d)\n", 
    lineWithMostChars, largestNumChars); 
} 

Answer 1

嘛，哪裏的首字母將會是您正在閱讀它們與第一fgetc電話，但像你的第二個電話fgetc你不putchar他們。

和totalNumChars是如此之大，因爲您定期將numChars添加到它，但您永遠不會將numChars重置爲零。

我希望這會有所幫助。玩得開心找到並搗毀這些錯誤！

Answer 2

首先，你在putchar()之前的行號。然後，在第二個while，test總是存儲'\n'，所以[numWords, numChars]總是在字母的下一行。正如@aecolley所說，numWords,numChars應該被重置爲零。

lineWithMostWords = lineWithMostWords; 

應該

lineWithMostWords = numLines; 

這是我的代碼，可能幫助你。

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

#define IN  1 
#define OUT  0 
#define MAXLINE 500 

void main() 
{ 
    int numChars = 0; 
    int numWords = 0; 
    int numLines = 0; 
    int state = OUT; 
    int test = 0; 
    int largestNumChars = 0; 
    int largestNumWords = 0; 
    int totalNumChars = 0; 
    int totalNumWords = 0; 
    int lineWithMostChars = 0; 
    int lineWithMostWords = 0; 
    char line[MAXLINE+1], *lineTemp; 
    int lineLen; 

    FILE *doesthiswork; 
    doesthiswork = fopen("testWords.in", "r"); 
    while (fgets(line, MAXLINE, doesthiswork) != NULL) 
    { 
     numChars = 0; 
     numWords = 0; 
     lineLen = strlen(line); 
     line[lineLen - 1] = '\0'; 
     lineTemp = line; 
     state = OUT; 

     ++numLines; 

     while ((test = *lineTemp++) != '\0') 
     { 
      ++numChars; 

      if (test == ' ' || test == '\t') 
      { 
       state = OUT; 
      } 
      else if (state == OUT){ 
       state = IN; 
       ++numWords; 
      } 
     } 

     totalNumWords = totalNumWords + numWords; 
     totalNumChars = totalNumChars + numChars; 

     if (largestNumChars == 0) 
     { 
      largestNumChars = numChars; 
     } 
     else if (largestNumChars < numChars) 
     { 
      largestNumChars = numChars; 
      lineWithMostChars = numLines; 
     } 

     if (largestNumWords == 0) 
     { 
      largestNumWords = numWords; 
      lineWithMostWords = numLines; 
     } 
     else if (largestNumWords < numWords) 
     { 
      largestNumWords = numWords; 
      lineWithMostWords = numLines; 
     } 

     printf("%d) %s [%d %d]\n",numLines, line, numWords, numChars); 
    } 
    printf("%d lines, %d words, %d characters\n", numLines, totalNumWords, totalNumChars); 
    printf("line %d has the most words with (%d)\n", lineWithMostWords, largestNumWords); 
    printf("line %d has the most characters with (%d)\n", lineWithMostChars,  largestNumChars); 
}
