- The absence of error warnings throughout the translation of a computer code is necessary but not sufficient for acceptable (programmatic) correctness, as previously stated by computer scientists Richard Conway and David Gries.Substitute another word or words for "necessary" and "sufficient" that together have the same meaning. (If it makes more sense to break it up into two sentences, by all means do so.)Discuss the concept of operator precedence and associativity in programming languages. Why is it important for understanding and writing correct code?What, in general terms, is the distinction between computer structure and computer function? Answer in brief.
- 3) Using the technique suggested here, where natural language descriptions arepresented in a standard format, write probable user requirements for the followingfunctions:i. The spelling-check and correcting function in a word processor.Perhaps it makes sense to investigate the wide variety of programming methods at our disposal. How can we account for the presence of so many competing paradigms? You are not free to choose otherwise. Your own words would help me understand it much better.10. Consider a language of expressions with only the variables a, b, and c and formed using the binary infix operators +, -, *, 7, and ↑ (for exponentiation) where ↑ has the highest precedence, * and / have the same next lower precedence, and + and - have the lowest precedence. ↑ is to be right associative and the other operations are to be left associative. Parenthe- ses may be used to override these rules. Provide a BNF specification of this language of expressions. Add attributes to your BNF specification so that the following (unusual) conditions are satisfied by every valid expression accepted by the attribute grammar: a) The maximum depth of parenthesis nesting is three. b) No valid expression has more than eight applications of operators. c) If an expression has more divisions than multiplications, then sub- tractions are forbidden.
- Discuss the concept of operator chaining in languages like Python and JavaScript. How does it simplify code and improve readability?2. Explain asynchronous versus synchronous as pertain to programming.Since the introduction of C Language by Dennis Ritchie in 1972, there has been more robust, flexible and pOwerful programming Languages af ter C, but, conventionally, when a student Learns C, there is a Likelihood that progressing to other Languages are usually not difficult. What is your understanding on this statement? Discuss with examples. 3:39 PM
- Discuss operator precedence and associativity in programming languages. Why is understanding these concepts essential for writing error-free code?4.Using pseudo-code, design and, in a suitable language, implement a working event-driven application to meet the above requirementsBriefly, discuss the Orthogonality characteristic of programming languages
