//Answer:
/*
Since classA is a class (which are reference objects),
you can change the contents inside A without passing it as a ref.
However, if you pass A as a ref, SetPrivateState can change what the original
A refers to. i.e. make it point to a different object.
A reference type is type which has as its value a reference to the appropriate data
rathar than the data itself
StringBuilder sb = new StringBuilder();
sb, create a new string builder object, and assign sb as a reference to the object
class, interface,delegate, array types are all reference types
structs and enums are value types
While reference types have layer of indirection between variable and real data,
value type dont. variables of value type directly contain data.
4 types of parameters in functions, default which is value,
reference ref, output out, and parameter arrays(params)
You can use any of them with both value and reference types!
By default parameter value type, new storage location created
for the variable in the function member declaration and it starts off
with the value that you specify in the function member invocation.
////////////////////////////////////
void Foo (StringBuilder x){
x = null;
}
StringBuilder y = new StringBuilder();
y.Append("hello");
Foo(y);
Console.WriteLine(y == null); //This is false because x is a copy of what y refers but now x refers to null
//if x was a ref parameter, then this would be true because they
dont pass the values of variables, they use the variables themselves
//The same storage locaiton is used rather than creating a new storage location
/////////////////////////////////////////////////
void Foo (StringBuilder x){
x.Append(" world");
}
StringBuilder y = new StringBuilder();
y.Append("hello");
Foo(y);
//When you pass y which is a class so reference type, do not think of this as
object being passed by reference, but object reference passed by value
Console.WriteLine(y); //returns "hello world",
//if y was value type, y would remain "hello" unless it was a ref parameter,
//then even if y was value type it would be "hello world"
Output parameters are very similar to reference parameters. The only differences are:
The parameter must be assigned a value before the function member completes normally.

//System.Object members
//all objects have a ToString() method which is a method defined in System.Object and which
//derieved classes can override to output something else. By default, ToString() method
//returns class name of the object as a string qualified by any relevant namespaces.
//Object Methods:
//Object() => Constructor
//~Object() => Destructor
//static virtual bool Equals(object,object) => checks whther the object paramter refers to the same object
//override for real check of states
//static bool ReferenceEquals(object,object) ==> checks whther they are references to the same instnace
//virtual string ToString() overide pls
//object MemberwiseClone() ==> protected method can only be used used from within the class or derieved classes
//member copies references which lead to references to samee objects
//System.Type GetType() //returns type in form of System.Type object
//virtual int GetHashCode() //Used as a hash function for objects where this is required. A hash function
//returns a value identifying the object state in some compressed form.
