Dear student, according to the question, the solution is as follows:
Thank you, All the best.

Write a BNF grammar that accepts an unsigned decimal number. This number can contain a single decimal point, if it does it cannot be the first character in the string, nor may it be the last. 5. W...
BNF 5. Write a BNF grammar that accepts an unsigned decimal number. This number can contain a single decimal point, if it does it cannot be the first character in the string, nor may it be the last.
In the first task, you will write a Java program that accepts a string of the format specified next and calculate the answer based on the user input. The input string should be of the format dddxxdddxx*, where d represents a digit and x represents any character and asterisk at the end represents that the string can have any number of characters at the end. 1. Prompt the user to enter a string with the specific format (dddxxdddxx*) 2. Read...
write a function which takes a string argument and a character argument. It should return a truth value (int 0 or 1), 0 if the string does not contain the character, and 1 if the string does contain the character. Do not use a built-in library for this. Again, call this function and its variables whatever you deem appropriate. The main function of the program should accept a single character followed by Enter. Then, it will read lines until the...
Can I get screenshots of the output. 1. SELECT a character string composed of the last two digits of the year of a title's pubdate, the pub_id, and the first ten characters of the title. 2. Display in one query output table the “id”, “name”, city, and state of both publishers and stores. 3. Write a SELECT statement that returns these columns from the Titles table: The price column A column that uses the CAST function to return the price...
Using loops with the String and Character classes. You can also use the StringBuilder class to concatenate all the error messages. Floating point literals can be expressed as digits with one decimal point or using scientific notation. 1 The only valid characters are digits (0 through 9) At most one decimal point. At most one occurrence of the letter 'E' At most two positive or negative signs. examples of valid expressions: 3.14159 -2.54 2.453E3 I 66.3E-5 Write a class definition...
1) Write SQL to return the first and last name of all actors with a first name of "ADAM" (use the ACTOR table) 2) Write SQL with the LIKE operator to return addresses that are in the "Dhaka" district and have street addresses that do not contain the character sequence "Loop". You can return all information from the ADDRESS table that matches this criteria. 3) Write SQL with the BETWEEN and ORDER BY clause to return the payments in descending...
Please note that I cannot use the string library function and that it must be coded in C89, thank you! Formatting: Make sure that you follow the precise recommendations for the output content and formatting: for example, do not change the text in the first problem from “Please enter a string of maximum 30 characters:” to “Enter string: ”. Your assignment will be auto-graded and any changes in formatting will result in a loss in the grade. 2.Comments: Header comments...
In either Java or Python 3, write a program that simulates a deterministic FSM. It will read from two input files. The first is a file describing an FSM The first line contains the alphabet as a series of characters separated by a single space - The second line contains the number of states as an integer k 2 1; states will be numbered 0,1,..., k -1. The start state is always state O The third line contains a series...

Write a C++ program that does the following : Accepts a positive integer ( n ) from the keyboard . Create an character array of size n. Using a random number generator, populate the array with characters between 33 – 126. Create 7 individual functions and perform the following 1. In the first function: display elements of the array. Display the first 20 elements If the size is > 20 2. In the second function : Using recursion, Search for...
