Bug #1
-----------------------------
Line
"void build_wordlist (string* word_list, int capacity, string filename)"
    must be changed to
"void build_wordlist (string*& word_list, int& capacity, string filename)"
    because
fuction build_wordlist should read words into word_list,so word_list and capacity should be passed by reference.

Bug #2
-----------------------------
Line
"new_word_list = word_list[index];"
    must be changed to 
"new_word_list[index] = word_list[index];"
    because
new_word_list is a pointer,the copy can be finished only if every memory location is changed to the correct assignment.

Bug #3
-----------------------------
Line
"string new_word_list = *(new string[2 * capacity]);" and "*word_list = new_word_list;"
    must be changed to
"string *new_word_list = new string[2 * capacity];" and "word_list = new_word_list;"
    because
we must store the address of the new list in the pointer new_word_list.

Bug #4
-----------------------------
Line
"delete word_list;
    must be changed to
"delete []word_list;"
    because 
deleting an array must be written like this "delete []'指向数组的指针';".
