So I have a program that reads through a file and gets the largest words by using a std::map with an int as the key and a std::vector as value. I need to print out the largest words but have a problem with the sorting. Whereas the output should be Copyright, Publishin, Universal, blueprint I get :blueprint, Copyright, Universal, Publishin
所以我有一个程序可以读取文件并通过使用std :: map获取最大的单词,其中int作为键,std :: vector作为值。我需要打印出最大的单词,但排序有问题。而输出应该是版权,发布,通用,蓝图我得到:蓝图,版权,通用,Publishin
How can I fix this? Do vectors not sort uppercase AND lowercase? Here's what I have so far:
我怎样才能解决这个问题?矢量不排序大写和小写?这是我到目前为止所拥有的:
string temp;
stringstream ss(line);
while(ss >> temp) {
int wordlength = temp.length();
wordit = wordbycount.find(wordlength);
if (wordit != wordbycount.end()) {
vector<string> arrayofLongest = wordit->second;
std::vector<string>::iterator iterator1 = find(arrayofLongest.begin(), arrayofLongest.end(), temp);
if (iterator1 == arrayofLongest.end()) {
wordit->second.push_back(temp);
}
}
else {
wordbycount[wordlength] = temp;
}
}

Do vectors not sort uppercase AND lowercase?
矢量不排序大写和小写?
No.
std::vectors doesn't sort (simply appending elements).
std :: vectors不排序(只是附加元素)。
std::vectors maintain the order of insertion.
std :: vectors维护插入顺序。
If you want an insert-and-ordering container, you should use std::set (or std::multiset).
如果需要插入和排序容器,则应使用std :: set(或std :: multiset)。
