Why do I get this error? I am at a loss...
error: request for member push_back
in v
, which is of non-class type std::vector<Leaf, std::allocator<Leaf> >*
class Leaf
{
public:
// Variables
std::string *name;
// Methods
Leaf(){}
Leaf(std::string *s)
{
name = s;
}
};
class Branch
{
public:
// Variables
Branch::Branch *parent;
Branch::Branch *child;
std::vector<Leaf> *children;
std::string *name;

Branch(std::string *s)

children = new std::vector<Leaf>;
开发者_运维问答 name = s;

};
class Tree

Tree(string *name)
{

}
void addBranch(Branch::Branch *newBranch)
{
this->current->child = newBranch;
newBranch->parent = this->current;
}
void addLeaf(Leaf::Leaf *leaf)
{
std::vector<Leaf> *v = this->current->children;
v.push_back(leaf);
}
};
In the function addLeaf()
v is a pointer, and leaf is a pointer, you need to dereference both of them.
v->push_back(*leaf);
Also, what's with all the scope qualifications, like Leaf::Leaf
and Branch::Branch
? It should just be Leaf
, and Branch
.
v
is a pointer to a vector. Use a ->
instead of a .
. i.e. v->push_back(whatsit)
