hi I'm learning c# Let's say I have this class

public class BST
{
public int value;
public BST left;
public BST right;
}

what is the name for public BST left, it's look like constructor but it's not

CodePudding user response：

The syntax you have is

public BST left;

...which is declaring a field in your class whose type is BST. This value of this field will be a reference to some other BST object, or possibly itself, or possibly null.)

The closest looking thing to what you have that is actually a constructor might look like

public BST(int left) {}

...which would be a constructor for the BST class that takes a single integer argument called left.

Remember that constructors look like methods with no return type, and the name of the method matches the name of the class.

CodePudding user response：

It's a member field, just like int value.

You have a recursive data structure; a Binary Search Tree, based on the name.

looks like constructor

No. Constructors don't have a return type, and need a code body and parentheses for zero or more parameters

Just a member of BST , not constructor , constructor like this BST() {}
