What is the relationship between a variable's type and the contents of the memory block associated with it in C#?
- The type of the variable and the contents of the memory block are unrelated
- The contents of the memory block depend on the context in which the variable was declared

Study Notes
Variables in C#
- A variable is a named storage location that holds a value.
- In C#, a variable has a specific type that determines the type of value it can hold.
Memory Storage in C#
- Variables in C# can be stored in either the stack or the heap, depending on their type.
- Value types (e.g., int, bool) are stored on the stack, whereas reference types (e.g., classes, arrays) are stored on the heap.
Variable Type and Memory Contents in C#
- A variable's type determines the format of the contents of the memory block associated with it.
- The type of a variable defines how the memory is interpreted, e.g., as a number, character, or reference.
