A code error about template and iterator of C++ made by a C++ new learner

As a C++ new learner, when I tried to learn about the template and iterator of C++, I wrote a function to check whether a number is amoung an array by using template and iterator of C++. The code is below:

template<typename T> bool find(vector<T>::iterator &begin, vector<T>::iterator &end, T target){
  for(;begin != end; begin++){
      if(*begin == target){
          return true;
      }
  }
  return false;
}


int main(void){
    vector<int> array{1,2,3,4,6,7};
    if(find(array.begin(),array.end(), 7)){
        cout << "find!";
    }
    else{
        cout << "not found!";
    }
} 

When I run the code above, I'll encouter the error, like this:

 template<typename T> bool find(vector<T>::iterator &begin, vector<T>::iterator &end, T target){
                                                                                        ^~~~~~

I just don't know what is wrong with the function and sincerely hope somebody can help!
