Chapter 7, Problem 16PS

Don't reject the question.  Provide answer step by step

For each one of the following languages over alphabet {a, b}, write an equivalent regular expression. (a) All strings made out of zero or more b's: (b) All strings that do not start with bb. (c) All strings that end with aaa or bb (d) All strings that start and end with the same alphabet letter.

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…

although java has the rule that the left operand of every binary operator is evaluated before the right operand, most languages give the compiler the freedom to choose which operand is evaluated first. when expressions have side effects, the value of the expression can be different depending upon which order is used. give an example in c++ of an expression whose value depends upon the evaluation order. show the orders that produce different values and the values they produce. explain what side effect is the expression contains.(dont copy and coursehero ans please) need elaborative ans

Please help me with this in c++. A simulation creates a model of a real-world situation, allowing us to introduce a variety of conditions and observe their effects. For instance, a flight simulator challenges a pilot to respond to varying conditions and measures how well the pilot responds. Simulation is frequently used to measure current business practices, such as the number of checkout lines in a grocery store or the number of tellers in a bank, so that management can determine the fewest number of employees required to meet customer needs. Airlines have been experimenting with different boarding procedures to shorten the entire boarding time, keep the flights on-time, reduce aisle congestion, and make the experience more pleasant for passengers and crew. A late-departing flight can cause a domino effect: the departure gate is tied up and cannot be used by other landing or departing flights, passengers on board the late flight may miss connecting flights and require rebooking and…

OBJECTIVE:Design a lexical analyzer for given language and the lexical analyzer should ignore redundant spaces, tabs and new lines. It should also ignore comments. Although the syntax specification states that identifiers can be arbitrarily long, you may restrict the length to some reasonable value. Simulate the same in C language.  PROGRAM LOGIC:   Read the input Expression       2.  Check whether input is alphabet or digits then store it as identifier       3.  If the input is is operator store it as symbol      4. Check the input for keywords     Thanks a lot in advance :)

Write a regular expression to describe each of the following languages. Example: {w = {a, b}* : w has both aa and bb as substrings} Regular expression: (a U b)* aa (a U b)* bb (a U b)* U (a U b)* bb (a U b)* aa (a U b)*

Why is it vital for today's programming languages to have both pass-by-value and pass-by-reference constructs? Why is it that we can't just choose one of these? Please address both the benefits of having both and the drawbacks of having either alone in your answer.

Logical Operators work with what kinds of operands? Give an example of each of the fundamental logical operators.
