C++ unable to assign objects passed as pointer in methods to variable


You need to declare and initialize storage for static objects:

Object_Class *MyClass::object =
nullptr;

void MyClass::setObject_Class(Object_Class *var) {
    object = var;
}

What will happen if assign a pointer an integer value in C ??
You cannot assign an integer value to a pointer object in C. There is one special case where you can appear to do so. A constant 0 (or more generally, an integer constant expression with the value zero) is a null pointer constant. But even in that case, the value is implicitly converted to a null pointer of the appropriate type, and it's that null pointer value, not an integer value 0, that will

Why do I need to assign to the pointer to a linked list when I modify it?
The method push() takes two arguments: a pointer to a pointer to a node (which is a pointer to the linked list) and a value to insert into the list. The reason why *head = temp; is necessary is so that the caller's linked list ends up getting modified. Without this line, the caller's linked list is not modified. Here's a highly simplified example of why this is necessary. Let's say I have a meth

OOP different objects need to run different methods (Java)
Even if you are using your own buttons, you could still adapt the pattern used by swing's JButton. With JButton you have a separate ActionListener class to execute the action (or multiple actions if you add more listeners). This way you can have a common buttons class that is responsible for it's design and being clickable, but delegates any interaction to the listeners. On a click, it will just c

Is it possible to use the time passed in a .transition() .duration() as a variable?
You are pretty flexible in these things, when using custom functions. Here, you are referring to 'style' attributes, so you might want to look at styleTween, like e.g. so: d3.select('#rect1') .transition().duration(500) .style("stroke-width", "10px") .styleTween("stroke", function() { return d3.interpolate("green", "red"); }); Alternatively, you can define your custom funct

Java Programming using Objects/ Methods
You are modifying the local variable amount, instead of modifying balance. In getWithdraw, change amount = balance - amount; to balance = balance - amount; and likewise for the getDeposit method. Incidentally, it's unclear why you are calling those methods getWithdraw and getDeposit, since those methods make withdrawals and deposits, respectively. I would have called them withdraw and dep
