我需要编写一个程序来查找单词的字谜。当程序启动时,它要求用户将单词输入“词典”,稍后将搜索用户将再次输入的单词的字谜。
我已经将字典中的所有单词存储在一个名为 oldDict
的 vector 中。然后每个单词中的字符按字母顺序排列,新的字符排序单词存储在一个名为 newDict
的 vector 中,以保留 oldDict
中的原始单词。
然后用户输入必须在字典中找到其变位词的单词。输入单词后,我再次尝试按字母顺序对单词的字符进行排序,然后将其与 newDict
中的每个元素进行比较,并以这种方式查找字谜。
下面是我的代码:
ifndef ANAGRAM_H
#define ANAGRAM_H
#include <iostream>
#include <vector>
#include <string>
using namespace std;
vector <string> oldDict;
vector <string> newDict;
int dictSize = 0;
void readDict(void){ // Allows the user to input all the words they would like to have in the anagram dictionary.
cout<< "Please enter the number of dictionary entries you wish to create\n";
cin >> dictSize;
string word = "";
cout << "Please enter the dictionary entries, 1 by 1, pushing <enter> after each entry.\n";
for(int i = 0; i <dictSize; i++){
cin >> word;
oldDict.push_back(word);
}
newDict = oldDict;
}
void sortChars(void){ //sorts the letters in each word of the 'dictionary' so that the letters are in alphabetical order.
for(int i = 0; i < dictSize; i++){
std::sort(newDict[i].begin(), newDict[i].end());
}
}
void getWords(void){
int num = 0;
cout << "Please enter the number of words for which you would like to find anagrams of:\n";
cin >> num;
string word = "";
for(int i = 0; i < num; i ++){
cout << "Please enter a word:\n";
cin>>word;
std::sort(word.begin(), word.end());
for(int i = 0; i < dictSize; i++){
string word2 = newDict[i];
bool isAn = isAnagram(word, word2);
if(isAn == true){
cout << oldDict[i];
} else{
}
}
}
}
bool isAnagram(string word1, string word2){
if(word1.compare(word2) ==0){
return true;
} else {
return false;
}
}
void menu(void){
readDict();
sortChars();
getWords();
}
#endif
该过程从代码底部的 order()
函数开始。
尝试编译代码时,我收到以下错误:
In file included from main.cpp:3:0:
./anagram.h: In function ‘void sortChars()’:
./anagram.h:25:3: error: ‘sort’ is not a member of ‘std’
std::sort(newDict[i].begin(), newDict[i].end());
^
./anagram.h: In function ‘void getWords()’:
./anagram.h:37:4: error: ‘sort’ is not a member of ‘std’
std::sort(word.begin(), word.end());
^
./anagram.h:40:38: error: ‘isAnagram’ was not declared in this scope
bool isAn = isAnagram(word, word2);
有人可以帮我解决这些错误吗?我真的不明白 'isAnagram' 给出错误,如果有人可以解释 'std::' 的作用以及为什么这两行代码会产生错误?
非常感谢
最佳答案
‘sort’ is not a member of ‘std’
添加#include <algorithm>
‘isAnagram’ was not declared in this scope
在首次使用之前声明函数。
此外,isAnagram 的实现看起来不正确。你不能简单地比较字符串。您应该在比较字符串之前对它们进行排序。
bool isAnagram(string word1, string word2){
std::sort(word1.begin(), word1.end()); // added
std::sort(word2.begin(), word2.end()); // added
if(word1.compare(word2) ==0){
return true;
} else {
return false;
}
}
