气泡根据大写和小写字母对字符串进行排序

Question

I am trying to bubblier sort my 2d array. Once I get to this point I get memory leaks:

te = word[i];
word[i] = word[i+1];

Once I get to this point I get a segment fault:

   word[i+1]=te;

I have tried using strcpy to copy the strings but I still get the segment fault error when I use it too.

void word_sorter(char** word,int numWord){

        int i =0;
        int j =0;
        for(i = 0; i < numWord; i++){

            for(j = 0; word[i][j] != '\0'; j++){


                        if(word[i][j]>= 'A' && word[i][j] <= 'Z'){

                                 char *te;
                                te =(char*)calloc(10000,sizeof(char));
                                te = word[i];
                                word[i] = word[i+1];
                                word[i+1]=te;



                        }



               }

        }

}

I am trying to sort the strings so that capital letters have precedence over lower case letter

INPUT: aand AAnd Aand
OUTPUT:AAnd Aand aand

Answer 1

You're allocating memory and assigning that address to te , then immediately overwriting that value with te = word[i] . This will leak the memory returned by calloc .

word[i+1] will access past the end of the array on the last iteration of the i loop, when i == numWord - 1 . This is the source of your segmentation fault.
