- Which of following will add 3 bytes at where the operation is specified and initialize it to "Hi" with a null terminated character appended to it? Question 6 options: msg: .STRING "Hi\x00" msg: .ASCII "Hi\x00" .WORD "Hi\x00" msg: .ASCII "Hi" Select the statement that is true about a parameter of a function that is passed-by-value. A. the reference to the real parameter is passed to the formal parameter B. changing the formal parameter inside the function causes change to the real parameter C. the real parameter cannot be a constant and has to be a variable D. changing the formal parameter inside the function will not change the realPYTHON3 Complete the given function, encrypt_text that encrypts the variable text using the provided key by applying a modified version of Caesar’s Cipher with the following rules: The key will contain a word made up of the letters ‘u’ and ‘d’. The cipher will use the key to determine the direction of the shift, with a ‘u’ indicating that the character must be shifted upwards while a ‘d’ indicating a downward shift. The number of characters in the key will determine the number of positions to shift. The given text variable will only contain characters from the ASCII table with values between 32 and 126. If the key is invalid (empty string, contains characters other than u and d) or the text is invalid (empty string), no encryption occurs and the function returns the original text. If the text has more characters than the key, the key will loop through again to accommodate the additional text characters. An iterative approach should be used to solve this problem. Brute force…Which of the following functions DOES NOT have a memory leak? Select one: void func(string word) { int* ptr = new int[2]; ptr[0] = word.size(); delete ptr; } void func(string word) { int* ptr = new int; *ptr = word.size(); } void func(string word) { int* ptr = NULL; int len = word.size(); ptr = &len; cout << "Length of " << word << " is " << *len << endl; }
- Which of the following is not true regarding the printf() function? a. The printf() function requires a format placeholder for each of the values it prints.b. The printf() function will convert a double into an int if the %d code is used.c. Any text in the format string that is not a format placeholder is printed exactly as it isfound.d. A single printf() function can be used to output more than one line of text.(5) Write a function called copy_even_lines() that takes two strings (filenames) as input parameters and copies every other line from the first file into the second. That is, counting from 0, it copies the 0th line, the 2nd line, the 4th line, etc. from the first file to the second file. You may assume that both files exist. (6) Write a python program that asks the user for two filenames and calls your function copy_even_lines() from (5) using those two filenames. If one or more files do not exist, your program must handle the exception by repeating the prompts until valid filenames are entered.What does function sqrt do? Which header file must be included to use the function sqrt? (3)
- Write a user-defined function called SumStop which takes an integer n as an input and adds up the values of the cells in row 1 (starting from cell A1) until the value of the sum exceeds n, and then outputs the number of cells used. You may assume that all of the cells in row 1 contain numbers. Use a suitable Do While loop and the cells command. Declare all variable types and include appropriate comments in your code. Write code in Excel VBA Code has to be for a function not a macro.Pleaser fix the code below: Since functions should do a single logical task, there is no need for the userInputCalc function to collect the info and also do the summary calculations, so move line 61 to line 72. Then, place line 67-72 inside a main() function, and place a call to this function at the end of the program file. Also, fix the names of the menu items (in menu_items) with spaces so they all have the same size. also, there is a simpler way: change {:<15} with {:<20} in lines 22 and 25. Also, use format for the “Subtotal” and “Grand total” (just like you did for “Sales tax” and “Suggested tip”) Also, the $ should go in front of the each amount. PLEASE MAKE THOSE CHANGES IN THE CODE BELOW: SummaryThis program will create a new version of the restaurant ordering programthat uses lists to look up menu items, record the items ordered by the user,and print a full receipt.''' def Menu(menu_items,menu_prices):print("Menu Card")count = 1for i,j in…Please assist, I am trying to modify the function so that it checks if the user is trying to register a name that already exists in user.txt, the appropriate message is displayed but it does not loop back to requesting the user to enter a new username.

Here is what I have so far in Python. # Define a function to register a new user.def reg_user(): while True: if menu == "r": if user_name == "admin" and password == "adm1n": new_user = input("Please enter a new username: ").lower() with open ("user.txt", "r") as new_file: read_file = new_file.readlines() for file in read_file: read_file = file.split(",") if new_user == read_file[0]: print("Invalid input.

- Create a Verilog function to calculate the factorial of a positive small integer this integer is passed through the function as an argument and a new integer and a new integer is returned as a result to the calling code ???Which function maps values between 0 and 1? * a) Sigmoid b) Tanh c) Error d) None of the aboveIn python, create a function adjust_values() with the arguments binaries and data. Binaries are only composed of binary values, and data are made up of integers. If binaries[0] is ‘0,’ the data should only be an even number. If it is, don’t change its value. If not, subtract 1 from it. If binaries[0] is ‘1,’ the data should only be an odd number. If it is, don’t change its value. If not, add 1 to it. Return the edited data in tuples of 3. Should the length of data be greater than the length of binaries, simply keep the remaining values as it is. To do (example below): binaries = 01001101 data = [201, 22, 93, 23, 344, 21, 53, 56, 22] The output should be in tuples of 3: [(200, 23, 92), (22, 345, 21), (52, 57, 22)]
