Given the code below: Read*,x,y,z If (.not. x*y−z<x/y.or.x>y) then print*, “Output is valid” else Print*,’It is needed more time to think’ Endif Print*, “End of the code” End Assuming default declaration types for all variables that have the values: x=2.0, y=4.0, z=3.0, what is the output of the code when executed? Question 4 options: Syntax error message when compiled It is needed more time to think End of the code Output is valid none of the given choices End of the code Run-time error message Output is valid End of the code
in the C++ version please suppose to have a score corresponding with probabilities at the end and do not use the count[] function. Please explain the detail when coding. DO NOT USE ARRAY. The game of Pig The game of Pig is a dice game with simple rules: Two players race to reach 100 points. Each turn, a player repeatedly rolls a die until either a 1 ("pig") is rolled or the player holds and scores the sum of the rolls (i.e. the turn total). At any time during a player's turn, the player is faced with two decisions: roll - if the player rolls 1: the player scores nothing and it becomes the opponents turn. 2 - 6: the number is added to the player's turn total and the player's turn continues. hold - The turn total is added to the player's score and it becomes the opponent's turn. This game is a game of probability. Players can use their knowledge of probabilities to make an educated game decision. Assignment specifications Hold-at-20 means that the player will choose to roll…

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.…
