我正在为我的 C 入门课程编写一个程序,该程序要求我根据教授给我们的字典文本文件编写一个程序来解决混乱的谜题(你知道,你在报纸上看到的那些字谜谜题)。它将字典中的单词按字母顺序排列,从文本文件(称为“jumble.txt”)中获取混乱,按字母顺序排列,然后运行字符串比较以找到匹配项。我已经编写了所有代码,但是当我尝试运行它时它立即崩溃,我不知道为什么。我想也许 Stackoverflow 用户可以在这里帮助我。
这是我的代码:
#include <stdio.h>
#include <strings.h>
#define MAX_WORD_LEN 6
#define MAX_NUM_WORDS 30000
typedef struct {
char word[MAX_WORD_LEN+1];
char sort[MAX_WORD_LEN+1];
} jumble_type;
void bubblesort(char letters[], int length);
int main () {
int words, jumbles;
int j, q;
jumble_type list[MAX_NUM_WORDS];
jumble_type list2[MAX_NUM_WORDS];
// Creating file pointers
FILE *ifp;
FILE *ifp2;
//Opens Jumble and dictionary files and reads the info from them
ifp = fopen("jumbledct.txt", "r");
ifp2 = fopen("jumble.txt", "r");
//Assigns the value of "words" to the first line of jumbledct.txt
fscanf(ifp, "%d", words);
//Assigns the value of "jumbles" to the first line of jumble.txt
fscanf(ifp2, "%d", jumbles);
// Reads the words from the dictionary into the "word" section of our
// list structure.
int i;
for (i = 0; i < words; i++){
fscanf(ifp, "%s", &list[i].word);
strcpy(list[i].sort, list[i].word);
bubblesort(list[i].sort, strlen(list[i].sort));
printf("%s\n", list[i].sort);
}
//Reads from Jumble.txt
for (i = 0; i < jumbles; i++){
fscanf (ifp2, "%s", &list2[i].word);
strcpy(list2[i].sort, list2[i].word);
bubblesort(list2[i].sort, strlen(list2[i].sort));
//printf("%s\n", list2[i].sort);
}
for(j=0;j<jumbles; j++){
printf("JUMBLE PUZZLE # %d: %s\n", j+1, list2[j].word);
int x=0;
for (q = 0; q < words; q++){
if(strcmp(list2[j].sort, list[q].sort)==0){
printf("%s\n", list[q].word);
x++;
}
}
if (x == 0){
printf("Sorry, this puzzle has no solutions. \n\n");
}
printf("\n");
}
return 0;
}
void bubblesort(char letters[], int length) {
char temp;
int x, y;
for(x = 0; x < length; x++){
for (y = x; y < length; y++){
if (letters[x] > letters[y]){
temp = letters[y];
letters[y] = letters[x];
letters[x] = temp;
}
}
}
}
提前感谢您的所有帮助。
