c++ – No matching member function for call to ‘push_back’ error

c++ – No matching member function for call to ‘push_back’ error

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

The error is because of the declaration:

std::vector<ship*> ships;

The vector contains pointers to mutable ships, but the code passes a pointer to a const ship to push_back. You either need to store const pointers in the vector:

 std::vector<const ship*> ships;

Or pass a non const pointer to the push_back:

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

Side note: move the above function to a cpp, move it to the body of the class, or declare/define it as inline, if you don’t want to get linker errors.
