** **** Exercise: 3 stars, standard (swap_exercise)
Write an Imp program [c] that swaps the values of [X] and [Y] and show that it satisfies the following specification:
{{X <= Y}} c {{Y <= X}}
Your proof should not need to use [unfold valid_hoare_triple].
Hints: - Remember that Imp commands need to be enclosed in <{...}> brackets. - Remember that the assignment rule works best when it's applied "back to front," from the postcondition to the precondition. So your proof will want to start at the end and work back to the beginning of your program. - Remember that [eapply] is your friend.) *)
Definition swap_program : com (* REPLACE THIS LINE WITH ":= _your_definition_ ." *). Admitted.
Theorem swap_exercise : {{X <= Y}} swap_program {{Y <= X}}.Proof. (* FILL IN HERE *) Admitted.(** [] *)From the book software Foundations Volume 2 coq proof
Answer the following sentences true or false
1. The loop execution is terminated on the basis of the test conditions.
2. A do..while loop is also called an exit-controlled loop.
3. A block of loop control statements in C are executed for number of times until the condition becomes false.
Answer the given question with a proper explanation and step-by-step solution.
Write an MIPS program that computes terms of the Fibonacci series, defined as:
1, 1, 2, 3, 5, 8, 13, 21, 34, 55 ... (This is sometimes started with a 0th term: 0, 1, 1, 2, etc.)The first two terms in the series are fixed, and each subsequent term in the series is the sum of the preceding two terms. So, for example, the term 13 is the sum of the terms 5 and 8.Write the program as a counting loop that terminates when the 100th term of the series has been computed. Use a register for the current term and a register for the previous term. Each execution of the loop computes a new current term and then copies the old current term to the previous term register. Count the number of passes to stop after the 100th term. Do not worry about overflow: this will FAR exceed the capacity of a register to hold the value.
Stop the program with a syscall with 10 in $v0.

- In my Introduction to Electronics course (300), we often run across division by zero. I know that it is technically undefined (or, at the very least, ambiguous), but sometimes we consider the value to be zero and other times to be infinity, which are, obviously, diametrically different (apart from negative numbers). I'm not so much interested in the nature of division by zero but more in how we determine whether we regard the value as zero or infinity? Again, this is in the context of electronics and circuit analysis, to be more specific. Thank you for your assistance.arrow_forwardCompute the weakest preconditions of the following statements for the given postconditions. Assume all variables are integers.(a) a = 2*b + 1;b = a*a + 1;{ a > 10 } (b) if (b > 0)a = 4*b - 10;elsea = b + 172;{ a > 0 }arrow_forwardWrite the mnemonics of the following program: The pressure of two boilers is monitored and controlled by a microcomputer works based on microprocessor programming.

A corresponding set of 6 reading from the second boiler is stored at the memory location starting from 2060H. Each reading from the first set is expected to be higher than the corresponding position in the second set of readings. Write an 8085 sequence to check whether the first set of reading is higher than the second one or not. If all the readings of first set is higher than the second set, store 00 in the ‘D’ register. If any one of the readings is lower than the corresponding reading of second set, stop the process and store FF in the register ‘D’.
