程序出错了大侠帮帮忙！
#include <vector>
#include <iostream>
using namespace std;

int main()
{
vector<string>svec;
svec.reserve(1024);
cout<<svec.size()<<" "<<svec.capacity();
string text_word;

while (cin>>text_word)
svec.push_back(text_word);
cout<<svec.size()<<" "<<svec.capacity();
svec.resize(svec.size()+svec.size()/2);
cout<<svec.size()<<" "<<svec.capacity();
return 0;
}


错误：

[解决办法]
#include <vector>
#include <iostream>
#include <string>
using namespace std;

int main()
{
vector <string> svec;
svec.reserve(1024);
cout <<svec.size() << " " <<svec.capacity();
string text_word;

while (cin >> text_word)
svec.push_back(text_word);
cout << svec.size() << " " << svec.capacity();
svec.resize(svec.size()+svec.size()/2);
cout <<svec.size() << " " <<svec.capacity();
return 0;
}

// 缺少头文件 <string> (另外操作符'<<'中间没有空格)
