C++ [STL] update whole existing vector data with new input

STL - vector

• clear() : Erases all elements from the container. After this call, size() returns zero.Leaves the capacity() of the vector unchanged.
• shrink_to_fit() : Requests the removal of unused capacity.

1. myCode

const std::vector<StudentS>& LocalDataImpl::getPeopleInformation(const std::vector<StudentS>& inputStudents )
{
    m_people.clear();
    m_people.shrink_to_fit(); // std::vector<StudentS> m_people 
 
    StudentS student;
    for (const auto& iStudent : inputStudents)
    {
        student.age = dotData.age;
        student.phone = dotData.phone;
        student.address = dotData.address;
        student.height = dotData.height;
        student.weight = dotData.weight;
        
        m_people.push_back(student);
    }
  
  return m_people;
}

1. comment

   if input value and member data has same type, please just assign data with ”=” directly

typedef struct StudentS
{
    int m_age;
    int m_phone;
    string m_address;
    int m_height;
    int m_weight;
    StudentS& operator=(const StudentS& data)  
    {
        this->m_age = data.m_age;
        this->m_phone = data.m_phone;
        this->m_address = data.m_address;
        this->m_height = data.m_height;
        this->m_weight = data.m_weight;
        return *this;
    }
    bool operator==(const StudentS& data) const 
    {
        return data.aflag == this->aflag && data.bflag == this->bflag;
    }
}StudentS;

const std::vector<StudentS>& LocalDataImpl::getPeopleInformation(const std::vector<StudentS>& inputStudents )
{
    m_people.clear();
    m_people.shrink_to_fit(); // std::vector<StudentS> m_people 
    m_people = inputStudents;
  
    return m_people;
}
