For any element in keysList with a value greater than 100, print the corresponding value in itemsList, followed by a space. Ex: If keysList = {42, 105, 101, 100} and itemsList = {10, 20, 30, 40}, print: 20 30 Since keysList.at(1) and keysList.at(2) have values greater than 100, the value of itemsList.at(1) and itemsList.at(2) are printed. #include <iostream>#include <vector>using namespace std; int main() {const int SIZE_LIST = 4;vector<int> keysList(SIZE_LIST);vector<int> itemsList(SIZE_LIST);unsigned int i; for (i = 0; i < keysList.size(); ++i) {cin >> keysList.at(i);} for (i = 0; i < itemsList.size(); ++i) {cin >> itemsList.at(i);} /* Your solution goes here */ cout << endl; return 0;} Please help me with this problem using c++.
The code given below represents a saveTransaction() method which is used to save data to a database from the Java program. Given the classes in the image as well as an image of the screen which will call the function, modify the given code so that it loops through the items again, this time as it loops through you are to insert the data into the salesdetails table, note that the SalesNumber from the AUTO-INCREMENT field from above is to be inserted here with each record being placed into the salesdetails table. Finally, as you loop through the items the product table must be update because as products are sold the onhand field in the products table must be updated. When multiple tables are to be updated with related data, you should wrap it into a DMBS transaction. The schema for the database is also depicted. public class PosDAO { private Connection connection; public PosDAO(Connection connection) { this.connection = connection; } public void…
Bar Graph, v 1.0 Purpose. The purpose of this lab is to produce a bar graph showing the population growth of a city called Prairieville, California. The bar graph should show the population growth of the city in 20 year increments for the last 100 years. The bar graph should be printed using a loop. The loop can be either a while loop or a for loop. Write a program called cityPopulation Graph.cpp to produce the bar graph. Requirements. 1. Use these population values with their corresponding years: 1922, 2000 people 1942, 5000 people 1962, 6000 people 1982, 9000 people 2002, 14,000 people 2012, 15,000 people 2022, 17,000 people 2. For each year, the program should display the year with a bar consisting of one asterisk for each 1000 people. 3. Each time the loop is performed (that is, each time the loop iterates) one of the year values is displayed with asterisks next to it. That is: 1st time loop is performed/iterates the year 1922 and the correct number of asterisks should be…
You may have found it somewhat tedious and unpleasant to use the debugger and visualizer to verify the correctness of your addFirst and addLast methods. There is also the problem that such manual verification becomes stale as soon as you change your code. Imagine that you made some minor but uncertain change to addLast]. To verify that you didn't break anything you'd have to go back and do that whole process again. Yuck. What we really want are some automated tests. But unfortunately there's no easy way to verify correctness of addFirst and addLast] if those are the only two methods we've implemented. That is, there's currently no way to iterate over our list and get bad its values and see that they are correct. That's where the toList method comes in. When called, this method returns a List representation of the Deque. For example, if the Deque has had addLast (5) addLast (9) addLast (10), then addFirst (3) called on it, then the result of toList() should be a List with 3 at the…
• Do not add statements that call print, input , or open , or add an import statement. • Do not use any break or continue statements. We are imposing this restriction (and we have not even taught you these statements) because they are very easy to abuse, resulting in terrible, hard to read code. • Do not modify or add to the import statements provided in the starter code. import math from typing import List, TextIO # For simplicity, we'll use "Station" in our type contracts to indicate that # we mean a list containing station data. # You can read "Station" in a type contract as: List[int, str, float, float, int, int, int] 23 # where the values at each index represent the station data as described in the # handout on Quercus. # A set of constants, each representing a list index for station information.
