“生成错误”错误-1073741819 - C [英] `Build Error` Error -1073741819 - C

问题描述

我的任务是从游戏Boggle中获取所有可能字母的数据文件。这是数据文件的副本：

$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ b IOSSET
NWEGHE
BOOJAB
UIENES
PSAFKF
IUNHM Qu
YRDVEL
VEHWHR
IOTMUC
TYELTR
STITYD
AGAEEN

每个骰子需要6个字母，在一个链表中。当我试图运行下面的代码，我不断收到错误代码： C：\Dev-Cpp\Makefile.win [Build Error] [Untitled1.o] Error -1073741819

我尝试过使用3个不同的IDE，但总是看起来会遇到一些编译问题。我似乎无法弄清楚我要去哪里错了！这还不是完整的，但是在我继续深入下去之前，宁愿搞清楚。
$ b

code ：

  #include< string.h> 
 #include< stdlib.h> 
 #include< stdio.h> 
 
 
 #define LENGTH 80 
 
 struct boggleDataNode {
 char data [3]; 
 struct boggleDataNode * nextData; 
} * head; 
 
 struct boggleDieSideNode {
 char dieSideData [3]; 
 struct boggleDieSideNode * nextSide; 
} * head1; 
 
 void readData（struct boggleDataNode temp）; 
 
 int main（）{
 int counter = 0; 
 struct boggleDataNode * head; 
 struct boggleDieSideNode * head1; 
 struct boggleDataNode * temp; 
 * head = NULL; 
 * head1 = NULL; 
 * temp = * head; 
 readData（* temp）; 
 
 
 system（pause）; 
返回0; 
 
 readData（struct boggleDataNode temp）{
 //初始化变量包括
 //打开输入文件
 FILE * input = fopen（BoggleData.txt ， R）; 
 int name = 0; 
 int id = 0; 
 char数据[96] = {}; 
 
检查文件是否打开
 if（input == NULL）{
 fprintf（stderr，Can not open input file！\\\
）; 
 exit（1）; 
 
 while（fscanf（input，％s，& data）！= EOF）
 printf（％s，data）; 
 
 $ b $ / code $ / pre 
 
解决方案
代码，更改 
 
 
  struct boggleDataNode {
 char data [3]; 
 struct boggleDataNode * nextData; 
} * head; 
  
到
  struct boggleDataNode {
 char data [3]; 
 struct boggleDataNode * nextData; 
}; 
  
好像你不需要这个结构的全局指针。根据你的使用情况，它将被本地的头遮蔽。
 
 
 
接下来，你分配 NULL 也是。 
>  >指向本身，而不是指向指向的变量。 （FWIW， NULL 本身是一个指针，虽然是一个无效的指针）。
 
 
 
 Change 
  * head = NULL; 
  
到
  head = NULL; 
  
 
my assignment is to take in a data file of all the possible letters for each die from the game Boggle. Here's a copy of the data file:
   D R L X E I
   C P O H S A
   N H N L Z R
   W T O O T A
   I O S S E T 
   N W E G H E
   B O O J A B
   U I E N E S
   P S A F K F
   I U N H M Qu
   Y R D V E L
   V E H W H R
   I O T M U C
   T Y E L T R
   S T I T Y D
   A G A E E N
Each die takes 6 of the letters, and these are stored in a linked list. When I have tried to run the following code, I keep getting an error code: C:\Dev-Cpp\Makefile.win [Build Error]  [Untitled1.o] Error -1073741819

I've tried using 3 different IDEs, but always seem to get some compiling issue. I can't seem to figure out where I'm going wrong! This isn't complete yet by any means but would rather figure this out before I keep going deeper and deeper. Thanks in advance!

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


#define LENGTH 80

struct boggleDataNode{
       char data[3];
       struct boggleDataNode *nextData;
}*head;

struct boggleDieSideNode{
       char dieSideData[3];
       struct boggleDieSideNode *nextSide;
}*head1;

void readData(struct boggleDataNode temp);

int main(){
    int counter = 0;
    struct boggleDataNode *head;
    struct boggleDieSideNode *head1;
    struct boggleDataNode *temp;
    *head = NULL;
    *head1 = NULL;
    *temp = *head;
    readData(*temp);


    system("pause");
    return 0;
}
void readData(struct boggleDataNode temp){
    //initializing variables including
    //opening the input file
    FILE *input = fopen("BoggleData.txt","r");
    int name =0; 
    int id=0;
    char data[96] ={};

    //error checking that the file opened
    if (input == NULL){
        fprintf(stderr, "Can't open input file!\n");
        exit(1);
    }
    while( fscanf(input, "%s", &data) != EOF)
           printf("%s", data);

}

解决方案
In your code, change
struct boggleDataNode{
       char data[3];
       struct boggleDataNode *nextData;
}*head;
to
struct boggleDataNode{
       char data[3];
       struct boggleDataNode *nextData;
};
as it seems you don't need a global pointer for that structure anyway. As per your usage, it will be shadowed by the local head.

Same goes for head1 also.

Next, you assign NULL to a pointer itself, not to the variable it points to. (FWIW, NULL itself is a pointer, an invalid one, though).

Change
*head = NULL;
to
head = NULL;
