Collection management: in this section, you will create a database and create single or compound indexes. the database data set collections are preloaded in your final project tool. a. utilize the mongoimport tool to create a database named “market” and a collection named “stocks,” loaded with documents from the stocks. json file. provide screenshots of the statements and the results of their execution. b. assess the need for indexing as you formulate queries and, using the mongodb shell, create any needed single or compound indexes. provide screenshots of the statements and the results of their execution. c. for all of your screenshots, explain in detail each part of the associated mongodb statements and their results to internal stakehol

In this lab, you complete a prewritten c++ program for a carpenter who creates personalized house signs. the program is supposed to compute the price of any sign a customer orders, based on the following facts: the charge for all signs is a minimum of $35.00. the first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character. if the sign is made of oak, add $20.00. no charge is added for pine. black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering. instructions ensure the file named housesign.cppis open in the code editor. you need to declare variables for the following, and initialize them where specified: a variable for the cost of the sign initialized to 0.00 (charge). a variable for the number of characters initialized to 8 (numchars). a variable for the color of the characters initialized to "gold" (color). a variable for the wood type initialized to "oak" (woodtype). write the rest of the program using assignment statements and ifstatements as appropriate. the output statements are written for you. execute the program by clicking the run button. your output should be: the charge for this sign is $82. this is the code, // housesign.cpp - this program calculates prices for custom made signs. #include #include using namespace std; int main() { // this is the work done in the housekeeping() function // declare and initialize variables here // charge for this sign // color of characters in sign // number of characters in sign // type of wood // this is the work done in the detailloop() function // write assignment and if statements here // this is the work done in the endofjob() function // output charge for this sign cout < < "the charge for this sign is $" < < charge < < endl; return(0); }

How do i copy and paste equations and pictures like math graphs, to post on this site to get my questions answered?

Suppose we are performing a binary search on a sorted array called numbers initialized as follows: // index 0 1 2 3 4 5 6 7 8 9 10 11 12 13 int[] numbers = {-2, 0, 1, 7, 9, 16, 19, 28, 31, 40, 52, 68, 85, 99}; // search for the value 5 int index = binarysearch(numbers, 5); write the indexes of the elements that would be examined by the binary search (the mid values in our algorithm's code) and write the value that would be returned from the search. assume that we are using the binary search algorithm shown in lecture and section.
