當試圖在eclipse上運行程序時，它崩潰

Question

我認爲它可能是某種類型的內存泄漏，當試圖讀取.txt文件。它只是停止響應和崩潰，我一般對編程相當陌生。

這是總的不完整的代碼：

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

#define MAXWORDLENGTH 60

Answer 1

WordsReadIn似乎不被遞增，從而可能導致一個除以0

此循環：

while (fgets(input, 100, pToFile)) { 
     sscanf(input, "%s", WordList[WordsReadIn]); 

    } 

我爲寫：

while (fgets(input, 100, pToFile)) { 
     sscanf(input, "%59s", WordList[WordsReadIn]); 
     ++WordsReadIn; 
    }
