Pointer to return value of vector iterator

I have a vector of structs e.g

struct IDS{
   string name;
   int age;
   IDS(string name, int age){
    this->name = name;
    this ->age = age;
   }
}

vector<IDS> myVector;

I am filling this vector with structs , and later on i want find a struct with specific value and save pointer to it. I tried using

IDS *tmp;

auto it = find_if (temp->myVector.begin(), temp->myVector.end(), [&](const IDS &y) { 
    return y.age == age; 
});

if ( it != temp -> myVector.begin() ){
    tmp =it
}

the vector is inside a linked list. This throws this error

cannot convert '__gnu_cxx::__normal_iterator

' to 'IDS*' in assignment|

How can i fix this error , and how can i store iterator pointer ?

it is an iterator, not a pointer. You can use tmp = &(*it); to convert the iterator to a pointer.

Alternatively you could make tmp a std::vector<IDS>::iterator.
