(Another Dangling-else Problem) Based on the dangling-else discussion in Exercise 4.23, modify the following code to produce the output shown. Use proper indentation techniques. You must not make any additional changes other than inserting braces. We eliminated the indentation from the following code to make the problem more challenging. [Note: It’s possible that no modification is necessary.]
if(y = = 8) if (x = = 5) cout << “@@@@@” << endl ; else cout << ”#####” << endl ; cout << ”$$$$$” << endl ; cout << “&&&&&” << endl ; a) Assuming x = 5 and y = 8, the following output is produced. @@@@@ $$$$$$ &&&&& b) Assuming x = 5 and y = 8, the following output is produced. @@@@@ c) Assuming x =5 and y = 8, the following output is produced. @@@@@ &&&&& d) Assuming x = 5 and y = 7, the following output is produced. [Note: The last three out-put statements after the else are all part of a block.] ##### $$$$$ &&&&&

- (Please do not give solution in image format thanku) Using the evaluation semantics of SML, rewrite the following expression into its simplest form. If the expression is syntactically illegal or its evaluation results in an error, then simply write "error" as the result. (fn f => (fn y => f y))(fn x => 1 + 1)arrow_forwardDO NOT USE EXISTING ANSWERS ON CHEGG OR COURSE HERO OR ANY OTHER SERVICES PLEASE! Thanks :) CODE IN PYTHON AND SHOW COMMENTS TO EXPLAIN CODE A confused Dutchman trying to speak English could say “I am in the war”, even though there is no hostile activity going on. The confusion1 here is that the English sentence “I am confused” is translated in Dutch as “Ik ben in de war”, which is phonetically (“sounding”) quite close to the first sentence. Such confusion leads to much enjoyment, but can complicate matters a bit. Given a sentence in Dutch and a dictionary containing both correct translations as well as phonetic (incorrect) translations of individual words, find the translation of the sentence and indicate whether it is correct, or in case there is more than one find the total number of correct and incorrect translations. A sentence is correctly translated when each word of the sentence is correctly translated.

- (Bar-Chart Printing Program) One interesting application of computers is drawing graphsand bar charts. Write a program that reads five numbers (each between 1 and 30). For each numberread, your program should print a line containing that number of adjacent asterisks. For example,if your program reads the number seven, it should print *******.arrow_forward(the use of .length and the importance of string) *please explain the use of .length in this statement, and the importance of string in our overall code* if (studentNumber.length() > 10) //2019104921 I goto loop; else if(studentNumber.length() < 10) goto loop;arrow_forwardIdentify and correct the errors in each of the following.

- Problem 4. (Regular Expressions-using Python re or Java regex) Write a regular expression for the following word patterns: 1. Word starts with a 'q'. Word has 'th'. 2. 3. Word has an 'q' or a 'Q'. 4. Word starts with an 'q' or an 'Q'. 5. Word has both 'o' and 'u' in it. 6. Word does not have an 'a'arrow_forward[Updated[ Python Code Pt1: Algorithms and Data Structures Please use the sample input to see if the code works, as the output of the final code, must be the same as the correct output.

Your code has to recognize the need for the second number and ask for it if required. After performing one operation, the calculator prints the output of the operation. After performing one operation, the calculator must not exit. It has to start again for the next operation. The calculator will be closed if the user writes 'e' as any input. Use functions to perform the operations and the appropriate conditions to prevent common errors such as entering characters as one of the numbers etc. b) Run your code and provide the results for at least one example per operation. - -arrow_forward
- Please answer item number 4. (pyhthon programming)arrow_forward(Financial: credit card number validation) Credit card numbers follow certain pat- terns. A credit card number must have between 13 and 16 digits. It must start with: 4 for Visa cards 5 for Master cards 37 for American Express cards 6 for Discover cards In 1954, Hans Luhn of IBM proposed an algorithm for validating credit card numbers. The algorithm is useful to determine whether a card number is entered correctly or whether a credit card is scanned correctly by a scanner. Credit card numbers are generated following this validity check, commonly known as the Luhn check or the Mod 10 check, which can be described as follows (for illustra- tion, consider the card number 4388576018402626): 1. Double every second digit from right to left. If doubling of a digit results in a two-digit number, add up the two digits to get a single-digit number. 4388576018402626 → 2 * 2 = 4 → 2 * 2 = 4 → 4 * 2 = 8 → 1 * 2 = 2 6 * 2 = 12 (1+ 2 = 3) → 5 * 2 = 10 (1+ 0 = 1) → 8 * 2 = 16 (1 + 6 = 7) → 4 * 2 = 8arrow_forwardHi!
