10-13. Verify User: The final listing for remember_me.py assumes either that the user has already entered their username or that the program is running for the first time. We should modify it in case the current user is not the person who last used the program. Before printing a welcome back message in greet_user(), ask the user if this is the correct username. If it’s not, call get_new_username() to get the correct username.
Array testGrades contains NUM_VALS test scores. Write a for loop that sets sumExtra to the total extra credit received. Full credit is 100, so anything over 100 is extra credit. Ex: If testGrades = {101, 83, 107,90), then sumExtra = 8, because 1 + 0 +7 + 0 is 8. 1 #include 2 3 int main(void) { 4 5 667809 B 10 11 12 13 14 15 16 17 } const int NUM_VALS = 4; int testGrades [NUM_VALS]; int i; int sumExtra = -9999; // Assign sumExtra with before your for Loop for (i = 0; i < NUM_VALS; ++i) { scanf("%d", &(testGrades[i])); } /* Your solution goes here */ printf("sumExtra: %d\n", sumExtra); return 0;
Brussel's choice def brussels_choice_step(n, mink, maxk): This problem is adapted from another jovial video "The Brussel's Choice" of Numberphile (a site so British that you just know there has to be a Trevor and a Colin somewhere in there) whose first five minutes you should watch to get an idea of what is going on. This function should compute and return the list of all numbers that the positive integer n can be converted to by treating it as a string and replacing some substring m of its digits with the new substring of either 2*m or m/2, the latter substitution allowed only when m is even so that dividing it by two produces an integer. This function should return the list of numbers that can be produced from n in a single step. To keep the results more manageable, we also impose an additional constraint that the number of digits in the chosen substring m must be between mink and maxk, inclusive. The returned list must contain the numbers in ascending sorted order.
In this exercise you will write a program for printing out grade statistics for a university course. The program asks the user for results from different students on the course. These include exam points and numbers of exercises completed. The program then prints out statistics based on the results. Exam points are integers between 0 and 20. The number of exercises completed is an integer between 0 and 100. The program kees asking for input until the user types in an empty line. You may assume all lines contain valid input, which means that there are two integers on each line, or the line is empty. And example of how the data is typed in: Exam points and exercises completed: 15 87 Exam points and exercises completed: 10 55 Exam points and exercises completed: 11 40 Exam points and exercises completed: 4 17 Exam points and exercises completed: Statistics: Sample output
Assignment 5A: Multiple Frequencies. In the last assignment, we calculated the frequency of a coin flip. This required us to have two separate variables, which we used to record the number of heads and tails. Now that we know about arrays, we can track the frequency of all numbers in a randomly generated sequence. For this program, you will ask the user to provide a range of values (from 1 to that number, inclusive) and how long of a number sequence you want to generate using that number range. You will then generate and save the sequence in an array. After that, you will count the number of times each number occurs in the sequence, and print the frequency of each number. Hints: You can use multiple arrays for this assignment. One array should hold the number sequence, and another could keep track of the frequencies of each number. Sample Output #1: What's the highest number you want to generate?: 5 How Long of a number sequence do you want to generate?: 10 Okay, we'll generate 10…

The language is C# Write a program named TestScoreList that accepts eight int values representing student test scores. Display each of the values along with a message that indicates how far it is from the average. An example of how the results should be output is as follows: Test # 0: 89 From average: 6 Test # 1: 78 From average: -5

Usage: mortgagepmt [-s] -r rate [-d downpayment] price In this assignment, you are asked to do a mortgage payment calculation. All information needed for this will be passed to the program on the command line. There will be no user input during the execution of the program. You will need a few pieces of information. The price of the home and the amount of the down payment. You will also need to know the interest rate and the term of the mortgage. To figure your mortgage payment, start by converting your annual interest rate to a monthly interest rate by dividing by 12. Next, add 1 to the monthly rate. Third, multiply the number of years in the term of the mortgage by 12 to calculate the number of monthly payments you’ll make. Fourth, raise the result of 1 plus the monthly rate to the negative power of the number of monthly payments you’ll make. Fifth, subtract that result from 1. Sixth, divide the monthly rate by the result. Last, multiply the result by the amount you want to borrow.…
Problem: An online grocery store sells items on a web page. A user adds items to a basket and he clicks on the submit button when he completes. The store sells food and electronic items. The electronic items require VAT payment of 15 percentage of their prices. There are packed and lose food. The lose food is measured in weights. User specifies the weight amount or the quantity in his selection of items depending on its type. The price is computed as the product of the price per item or the price per weight and the weight or quantity are given by the user. Write an application that reads a user basket list and produces the bill receipt. Check the given samples of input/output in the figures below. The bill receipt contains the list of item details in decreasing order according to the price computed for each item. Use the selection sort' to sort the items in the list and do not use java given sort method. Selection sort is an algorithm used to arrange elements in a list. It selects the…
