A data type is a value type if it holds the data within its own memory allocation. All value based types are allocated on the stack. When a value type is assigned to another value type, it is copied.
Reference Type
A reference type contains a pointer to another memory location that holds the data or we can say reference type contains a reference to the value. Reference based types are allocated on the heap. When a reference type is assigned to another reference type, a reference is assigned to the value.
