I’m building a new program, but when I run it, an error pops up. The error displayed is as follows:

No matching member function for call 'push_back'

I have tried several workarounds, but they still do not get the desired results. If you have come across this situation and have a solution for the “no matching member function for call to ‘push_back’” problem, please let me know. Here is what I do:

//fleet.h 
 #include "ship.h"
 #include <vector>
 #include <iostream>
 #ifndef fleet_h
 #define fleet_h
 using namespace std;
 
 class fleet
 {
 public:
 
 //Add_ship and remove_ship method
 bool add_ship(ship const &s);
 
 private:
 vector<ship*> ships;
 };
 
 //Add_ship method
 bool fleet::add_ship(ship const & s){
  ships.push_back(&s); 
  return true;
 }
 #endif /* fleet_h */

Thanks!

    The cause:

    The reason for the error is the declaration:

    std::vector<ship*> ships;

    Solution:

    You should store const pointers in the vector in this way:

     std::vector<const ship*> ships;

    Another way: moves a non const pointer to push_back:

    fleet::add_ship(ship & s)
{
ships.push_back(&s); (No matching member function for call to 'push_back')
return true;
}
