一言难尽,我相当于重写了,你参考下吧...#include<iostream>
#include <string>
#include <vector>
#include <algorithm>
using namespace std;
struct WORD
{
string word;
int count = 1;
bool operator()(const WORD& a, const WORD& b)
{
return a.word < b.word;
}
};
void input(vector<WORD>& words)
{
char c;
string temp;
WORD tWord;
cout << "输入几个英语单词:";
//从这里开始就不对,不要用cin....
//题目上说单词中间是空格隔开
//不是回车区分单词
while (c = getchar())
{
if ((c >= 'A' && c <= 'Z') || c >= 'a' && c <= 'z')
temp.append(1, c);
else if (c == ' ' || c == '0')
{
tWord.word.assign(temp);
words.push_back(tWord);
temp = "";
if (c == '0')
break;
}
}
}
void order(vector<WORD>& words)
{
//去重
for (int i = 0; i < words.size() - 1; ++i)
{
for (int j = i + 1; j < words.size(); ++j)
{
if (words[i].word == words[j].word)
{
words[i].count += 1;
words.erase(words.begin() + j);
j -= 1;
}
}
}
//排序
sort(words.begin(), words.begin() + words.size(), WORD());
}
void VectorPrint(const vector<WORD>& words)
{
for (const auto& item : words)
{
printf_s("%s : %d\n", item.word.c_str(), item.count);
}
}
int main()
{
vector<WORD> words;
input(words);
order(words);
VectorPrint(words);
return 0;
}
