C++编译时出现 reference to local variable

具体见：https://stackoverflow.com/questions/19371137/c-reference-to-local-variable-returned

• 会引发问题的实现如下：

vector & find1(string &search_word)
{
    vector final;
final.push_back(2);
final.push_back(5);


return (final); //This is giving me the error when I try to return the vector.

}

int main ()

{
string search;

cin >> search;

vector  &p = find1(search);


}

• 修改find1方法返回对象而不是引用

//错误的
//在find1方法结束时，方法内部的局部变量就会被清楚
std::vector& find1(std::string& search_word)
std::vector& p = find1(search);

//正确的
//使用对象，而不是引用
vector find1(string &search_word); //返回类型从引用变成对象
std::vector p = find1(search);
