1. In using scanf the reference to data was always passed. When using printf the reference was passed for a string, but the data value was required for types such as integer. This says that what is commonly refer to as a variable actually has 3 parts: 1 - The label (sometimes called the id or name); 2 - the reference; 3 - the value. Explain to the best of your understanding what is the difference between each of these three parts, and how it changes the cognitive model or metaphor you use to understand a variable. The type of the variable (how the variable is stored and operations on the variable) are associated with what part of the variable, the label, reference, or value? 2. Which parts of the variable exist at compile time, and which parts exist at run time? 3. Harder question with more insight: Can a value be a reference? Can you think of an example? (Think of structs and arrays). 4. Even harder, this is a real world example. I read that Python has immutable primitive types (e.g.…
