- When it comes to evaluating expressions, what are the benefits of being able to do so without having to define actions inside the grammar?What is the “dangling else” problem? How is it avoided in modern languages?How do functional languages typically control repetition? Group of answer choices recursion implication denotation iteration
- What is the name of the mathematical machine that both top-down and bottom-up parsers are built on?Why is it vital to distinguish between changeable and immutable values when implementing a language with a reference model of variables?Write a BNF description of the Boolean expressions of Java, including the three operators &&, ||, and ! and the relational expressions.
- Analyze the concept of operator precedence in regular expressions. How can it affect the matching and parsing of text patterns?Why do modern programming languages need to support both value and reference passing? When deciding between these two alternatives, why is it so difficult to choose only one? Your solution should address both the positives of having both and the drawbacks of having either alone.What is the mathematical machine on which both -top--down and -bottom--up parsers are based?
- Does the programming language C provide a sufficient amount of support for relational and boolean expressions?Explain the operator precedence and associativity in programming languages. How does it affect the order of evaluation in complex expressions?Finish the 2 "TODO" in the ASM Language! A palindrome is a word that is spelled the same way forwards and backwards. For example, "radar", "racecar", "civic", "kayak", and "madam" are all palindromes. The definition can be extended to phrases and sentences when ignore case and punctuation, but for this exercise we will stick to a single word. The starter code provided uses the C library functions printf and scanf to prompt for an input a word. The word that is entered from the keyboard is a null-terminated string placed in the byte array at address buf. There are also two output strings provided at addresses str_is_palindrome and str_is_not_palindrome. The starter code provided simply outputs the string at str_is_not_palindrome. The code contains two TODO comments... At the first TODO comment, the byte array at buf is filled with input from the keyboard. This input is a null-terminated character string (i.e. the array contains the characters entered on the keyboard, followed by ASCII…
