使用迭代器打印set的成员 [英] Printing members of set using iterators

问题描述

我有这个代码打印出字符串有些单词要解析为一组字符串，这几乎可以正常工作。它打印出字符串，但输出顺序不正确。有人看错了吗？





set< string> myset = parseStringToWords（一些要解析为一组字符串的单词）;

set< string> :: iterator iter;

cout<< myset.size（ ）<< endl;

int i = 0;

for（iter = myset.begin（）; iter！= myset.end（）; ++ iter ）{

cout<<（* iter）<< endl;

i + = 1;

cout<< i< < endl;

}

解决方案

容器集会自动对关键字进行排序，因此输出与输入顺序不同。 / BLOCKQUOTE>

I have this code to print out the string "Some words to parse to a set of strings", which almost works. It prints out the string, but not in the right order. Anyone see anything wrong?


set<string> myset = parseStringToWords("Some words to parse to a set of strings");
set<string>::iterator iter;
cout<<myset.size()<<endl;
int i=0;
for(iter=myset.begin(); iter!=myset.end();++iter){
cout<<(*iter)<<endl;
i+=1;
cout<<i<<endl;
}

解决方案

The container set would sort your keywords automatically, so the output is different from the input order.
