Cut and paste your code from Eclipse into the Assignment text window. This is another password program. In this case, your code is simply going to ask for a username and password, and then check the input against four users. The program will give the user three tries to input the correct username-password combination. There will be four acceptable user-password combinations: • alpha-alpha1 • beta-beta1 • gamma-gamma1 • delta - delta1 If the user types in one of the correct username-password combinations, then the program will output: "Login successful." Here are a couple of example runs (but your code needs to work for all four user-password combinations): Username: beta Type your current password: beta1 Login successful. Username: delta Type…arrow_forwardWhen a procedure takes both stack arguments and local variables, what phrases should be included in the procedure's epilogue?arrow_forward
- Part 3. arange Method Define a method in simpy named arange. Its purpose is to fill in the values attribute with range of values, like the range built-in function, but in terms of floats. It has three parameters in addition to self, the last being optional: 1. start - a float indicating the first value in the range 2. stop - a float that is not included in the produced range values 3. step - a float whose default value is 1.0 that indicates how to increase (or decrease) each subsequent item in the generated range. Unlike the built- in range function, this can be a fractional, float value. Step cannot be 0.0. Think carefully about what the value of step tells you about how to design your loop(s) for this method. Before any looping, you should assert step != 0.0 to be sure you avoid an infinite loop with an invalid argument. positive = Simpy([]) positive.arange(1.0, 5.0) print("Actual: ", positive, " - Expected: Simpy([1.0, 2.0, 3.0, 4.0])") fractional = Simpy([]) positive.arange (0.0,…arrow_forwardCreate a list that contains 10 words and their descriptions. Your task is to have the application randomly select a word from the list and display the description to the user. User will then try to guess the word based on the clue displayed. One round of game is five chances. Once the total number of chances becomes zero, the program should prompt the user whether to keep playing or exit the application.arrow_forwardPlease add comments! thanks!arrow_forward
- Assume the variable s has been assigned a value and my_set refers to a set. Write code that determines whether s is in my_set. If so, assign True to the found variable. Otherwise, assign False to found.arrow_forward3. Which among the following shows a valid use of the Direction enumeration as a parameter to the moveCharacter function? Select al that apply. enum Direction { case north, south, west, east}func moveCharacter(x: Int, y: Int, facing: Direction) {// code here} moveCharacter(x: 0, y: 0, facing: .southwest) moveCharacter(x: 0, y: 0, facing: Direction.north) moveCharacter(x: 0, y: 0, facing: .south) moveCharacter(x: 0, y: 0, facing: Direction.northeast)arrow_forwardUsing C++ Language Assign numMatches with the number of elements in userValues that equal matchValue. userValues has NUM_VALS elements. Ex: If userValues is {2, 1, 2, 2} and matchValue is 2 , then numMatches should be 3.Your code will be tested with the following values:matchValue: 2, userValues: {2, 1, 2, 2} (as in the example program above)matchValue: 0, userValues: {0, 0, 0, 0}matchValue: 10, userValues: {20, 50, 70, 100} code: #include <iostream>using namespace std; int main() { const int NUM_VALS = 4; int userValues[NUM_VALS]; int i; int matchValue; int numMatches = -99; // Assign numMatches with 0 before your for loop cin >> matchValue; for (i = 0; i < NUM_VALS; ++i) { cin >> userValues[i]; } /* Your solution goes here */ cout << "matchValue: " << matchValue << ", numMatches: " << numMatches << endl; return 0;}arrow_forward
- Make any necessary modifications to the RushJob class so that it can be sorted by job number. Modify the JobDemo3 application so the displayed orders have been sorted. Save the application as JobDemo4. An example of the program is shown below: Enter job number 22 Enter customer name Joe Enter description Powerwashing Enter estimated hours 4 Enter job number 6 Enter customer name Joey Enter description Painting Enter estimated hours 8 Enter job number 12 Enter customer name Joseph Enter description Carpet cleaning Enter estimated hours 5 Enter job number 9 Enter customer name Josefine Enter description Moving Enter estimated hours 12 Enter job number 21 Enter customer name Josefina Enter description Dog walking Enter estimated hours 2 Summary: RushJob 6 Joey Painting 8 hours @$45.00 per hour. Rush job adds 150 premium. Total price is $510.00 RushJob 9 Josefine Moving 12 hours @$45.00 per hour. Rush job adds 150 premium.
