- you wrote a software simulation of a computer that executes programs written in Simpletron Machine Language (SML). In this exercise, we propose several modifications and enhancements to the Simpletron Simulator. In Exercises 19.30–19.34, we propose building a compiler that converts programs written in a high-level programming language (a variation of BASIC) to SML. Some of the following modifications and enhancements may be required to execute the programs produced by the compiler. [Note: Some modifications may conflict with others and therefore must be done separately.] Allow the simulator to perform exponentiation calculations. This requires an additional Simpletron Machine Language instruction.you wrote a software simulation of a computer that executes programs written in Simpletron Machine Language (SML).

Some of the following modifications and enhancements may be required to execute the programs produced by the compiler. [Note: Some modifications may conflict with others and therefore must be done separately.] Modify the simulator to handle string input. [Hint: Each Simpletron word can be divided into two groups, each holding a two-digit integer. Each two-digit integer represents the ASCII decimal equivalent of a character. Add a machine-language instruction that inputs a string and store the string beginning at a specific Simpletron memory location. The first half of the…Q4:3- Answer with T or F (1) Compilation time can be reduced by having [5 pt] Figure 1.6: Phases of a compiler multiple passes. (2) Front end phase is machine independent (3) Lexical analysis phase optimize the generated code. (4) Symbol Table contains information about all identifiers used in the input code. (5) Method name is an identifier (6) Reserved words are identifiers (7) A delimiter is always a space (8) Regular expressions can define any language (9) Lexical rules of a language is defined with finite state machine. (10) Any Nondeterministic finite state machine can be converted to a deterministic finite state machine.
- 4. Often some situation arises in programming where data or input is dynamic in nature, i.e. the number of data item keeps changing during program execution. A live scenario where the program is developed to process lists of employees of an organization. The list grows as the names are added and shrink as the names get deleted. With the increase in name the memory allocate space to the list to accommodate additional data items. Such situations in programming require which technique. Explain the concept with the help of suitable examples.(c++ language only)What input or parameter value impacts the number of times the recursive function will be called. • Give three specific examples of input/parameter values and, for each, state the number of times the recursive function will be called. • Devise a formula with respect to n that describes the number of times the recursive function will be called, where n is either the value passed or some property of the value passed (e.g. n might be the length of a string of the size of an array).Question 1 a) When developing a program, it is important to put yourself in the user mind. Why? Answer: e) O(N?) is the running time of a type of complexity class. Explain what complexity class is and explain the type class presented by 0(N). Answer: b) How to be critical thinker in finding defects during software testing. Answer: Question 2 a) Tuple, List, Dictionary and Set are Python data type. Compare these three data types. Answer: c) A sink trap is an example of an elegant product. Explain why sink trap is considered as elegant and give another example of elegant product. CROSS SECTION OF A TRAP Answer: d) What are common asked in evaluating a solution? Explain each of them. Answer:
- System Description Data Dictionary (Description of each table and attribute) Conceptual Model (Entity/Relationship Model) Logic Model (Relational Model) Database Schema Script (DDL). 3.5 A dentist’s office needs to keep information about patients, the number of visits they make to the office, work that must be performed, procedures performed during visits, charges and payments for treatment, and laboratory supplies and services. Assume there is only one dentist, so there is no need to store information about the dentist in the database. There are several hundred patients. Patients make many visits, and the database should store information about the services performed during each visit and the charges for each of the services. There is a standard list of charges, kept outside the database. The office uses three dental laboratories that provide supplies and services, such as fabricating dentures. Draw a complete E-R diagram for this exampleHCI is (Human Computer Interaction) Answer the following five statements by first stating whether it is true or false and then given one sentence for justifying your answer a) You drag a folder to make a copy of its contents. An animation appears on the screen, showing files moving from one folder to another. This is an example of feedback. b) In augmented reality a screen is composed of a computer animation of the reality. c) The Model Human Processor is used in HCI to model complex cognitive processes d) Petri Nets can be helpful in modeling concurrent activities in a user interface. e) Gestalt is important to HCI as it offers tools to understand scenes.Lab Task: You are required to make changes in the above programs and introduce the use of compaction where required. Write code to simulate Worst-Fit Algorithm Write a C program to simulate the MVT and MFT memory management techniques. Write a C program to simulate the following contiguous memory allocation techniques Worst-fit Best-fit First-fit TASK1: DESCRIPTION MFT (Multiprogramming with a Fixed number of Tasks) is one of the old memory management techniques in which the memory is partitioned into fixed size partitions and each job is assigned to a partition. The memory assigned to a partition does not change. MVT (Multiprogramming with a Variable number of Tasks) is the memory management technique in which each job gets just the amount of memory it needs. That is, the partitioning of memory is dynamic and changes as jobs enter and leave the system. MVT is a more ``efficient'' user of resources. MFT suffers with the problem of internal fragmentation and MVT suffers with…
