Many functions are compiled to first pushq %rbp, then copy rsp into %rbp. Why push %rbp? A. So that local variables can be indexed off of %rsp even if the function pushes or pops other values B. So that local variables can be indexed off of %rbp even if the function pushes or pops other values C. So the old value of %rsp can be restored at the end of the function D. So the old value of %rbp can be restored at the end of the function

We are going to write a program to create a word puzzle. For now, what we need is a function promptletnum that will prompt the user for one letter and an integer in the range from 1 to 5 (inclusive), error-checking until the user enters valid values, and then return them. The function will convert upper case letters to lower case. This function might be called from the following script wordpuz: wordpuz.m (1, n] = promptletnum; fprintf('We will find words that contain the \n') fprintf('letter ''tc'' %d times.\n', 1, n)
In c++, please. Thank you! Given a main() that reads user IDs (until -1), complete the BubbleSort() functions to sort the IDs in ascending order using the Bubblesort algorithm, and output the sorted IDs one per line. You may assume there will be no more than 100 user IDs. Ex. If the input is: kaylasimms julia myron1994 kaylajones -1 the output is: julia kaylajones kaylasimms myron1994 The following code is given: #include <string>#include <iostream> using namespace std; // TODO: Write the Bubblesort algorithm that sorts the array of string, with k elementsvoid Bubblesort(string userIDs [ ], int k) { } int main() { string userIDList[100]; string userID; cin >> userID; while (userID != "-1") { //put userID in the array cin >> userID; } // Initial call to quicksort Bubblesort(userIDList, /* ?? */ ); //make this output only the userIDs that were entered, not garbage for (int i = 0; i < 100; ++i) { cout <<…

Write a function, Decode() that can analyse a list of card numbers. The function is constructed as follows:The function receives the string list (as in Question 3.1) as parameter and returns no value to the calling statement.When this function executes the following should happen:Each card number in the list should be analysed in turn to extract the encoded information in the following format:0318241215528881: Was issued by Diner’s club in 2018. The card expires on 24/12. The card is linked to a Credit account with account number: 15528881.It may be assumed that any year (YY) refers to the years 2000+.The information for each card number must be stored in one string variable. The variable must then be sent to the WriteFile() function (see Question 3.3 below) so that the result can be saved. The process repeats until each card number in the list is sent to the WriteFile() function.

Using informal arguments: Write a function polynomial which implements a polynomial function of arbitrary integer order ?: ?(?)=?0+?1?+?2?2+⋯+???? The function should take ? as a formal argument and the constants {??} as informal arguments. You will have to use the *args function argument. The enumerate builtin function will also be convenient in order to get the power ? to go along with each ??. Recall, you can index tuples just like arrays by using [ ]. Test your function by plotting: ?(?)=1+2?2 over the range (-3,3).
Please answer it in Python Write a function can_write(letters, word) that returns True if the word of argument word can be written using letters from the string letters, False otherwise. For example: >>> can_write("tatxslua", "salut") True >>> can_write("lasautaionna", "salutation") # not enough "t" False
Assume (or you can create it) a function for detecting prime numbers is created. Then, write a script file in MATLAB that will call that function for all number between 600 and 999, find the twin primes, safe primes, sexy primes, and Mersenne primes and "good" friends. Note: I already have the function (isprime(num)). I want the script file following the above conditions.
