i got some issues trying to put the values of my vector in a new map (maMap) If someone could explain me what contain my ItemIterator or how to do...
map<std::string,Employee*> Entreprise::convertiVectorMap() const
{
map<std::string,Employee*> maMap;
vector<Employee*>::const_iterator ItemIterator;
for(ItemIterator = vector_employe.begin(); ItemIterator != vector_employe.end(); ItemIterator++)
{
maMap.insert(std::pair<string,Employee*>(ItemIterator->getNom(),ItemIterator));
}
}
You forgot to derefrence your iterator:
maMap.insert(std::pair<string,Employee*>((*ItemIterator)->getNom(),*ItemIterator));
And since everyone asks for a revamped version of your code here we go:
map<std::string,Employee*> Entreprise::convertiVectorMap() const
{
map<std::string,Employee*> maMap;
for(vector<Employee*>::const_iterator ItemIterator = vector_employe.cbegin(),
ItemIteratorEnd = vector_employe.cend();
ItmeIterator != ItemIteratorEnd; ++ItemIterator)
{
Employee* ptr = *ItemIterator;
maMap.insert(std::make_pair(ptr->getNom(),ptr));
}
}
You can also use ranged based for if you're at least in C++11.
Your map is of <std::string, Employee*>
, but you are trying to add an iterator as the second element of the pair
. You need to dereference the iterator to get the Employee
pointer.
maMap.insert(std::pair<string,Employee*>((*ItemIterator)->getNom(), *ItemIterator));
Or to save from dereferencing the same iterator twice, you could just use a range based for
loop. As @CaptainObvlious mentions, you can also use std::make_pair
to add to your map
.
for(auto const employee: vector_employe)
{
maMap.insert(std::make_pair(employee->getNom(), employee));
}
