迭代器的几种遍历输出方式

#include<vector>

#include<string>

#include<iostream>

using namespace std;

int main(){

vector<string> text;

string word;

while (getline(cin, word)){//循环读入字符串至vector<string>中，以trl+z回车结束

text.push_back(word);

}

//下标迭代方式输出

cout << "下标迭代方式输出" << endl;

for (vector<string>::size_type ix = 0; ix != text.size(); ++ix)

cout << text[ix] << endl;

 

//迭代器方式输出

cout << "迭代器方式输出" << endl;

for (vector<string>::iterator it = text.begin(); it != text.end(); it++){

cout << *it << endl;

}

//int result = uniqueMorseRepresentations(text);

 

//精简迭代方式输出

cout << "精简迭代方式输出" << endl;

for (const string& words : text){

cout << words << endl;

}

getchar();

return 1;

}
