(Sentinel-Terminated Average) In this question, we are interested in computing the average of a set of numbers given in a vector. However, the list of numbers may include a sentinel value (-999) that terminates the list of numbers whose averages we would like to compute. If the sentinel is not present, we wish to compute the average of all of them. If the sentinel is present, we wish to only compute the average of the numbers preceding (and not including) the sentinel. sentinel_avg Function: Input variables: • a vector of numbers that may include the sentinel value -999 (note: you may assume there is at least one number in this list preceding the sentinel) Output variables: • a scalar representing the average of the desired numbers A possible sample case is: » [avg] = sentinel_avg([1 2 3 4 -999 -5 -5 -5]) avg = 2.5 » [avg] = sentinel_avg([4 2 3]) avg = %3D

C PROGRAMMING HELP I need help fixing an old assignment of mine. The point of the script is to read the pasted/attached Number_new.txt file's contents, meant to represent a classes' final grades out of 100 percent, and print an .exe screen as well as another .txt file that repeats the grade number with a letter grade and a PASS or FAIL next to it. At the end it needs to say how many students passed and how many failed. Nothing too complicated with the grading, just 90.0 and up is an A, 80.0 to 89.99 is a B, etc. And of course, anything below 60.0 is an F/FAIL. Please NO IOSTREAM.H OR CACIO.H! I cant use those header files. Below is the script: #include<stdio.h>#include<math.h>#define THEFILE "Number_new.txt" int main(){ float r0[10]; float rr[10]; FILE *fp; char line[81]; fp = fopen(THEFILE, "Number_new.txt"); if (fp != NULL) { /* The file is open. */ printf("%7s %7s %7s %7s %7s %7s %7s %7s %7s %7s\n", "0", "0.01",…

Program Name: <LastNameFirstInit>_PetShelter You work at a Pet Shelter that take in homeless pets. You have been tasked with creating a report that shows a list of all the dog breeds currently staying at the shelter. This list should include the breed name along with the count for each breedcurrently being housed at the shelter. In addition, at the end, the report should display the name of breed that we have the most (max) of currently at the shelter. In addition, your program should utilize methods for building the report and searching for the max breed count. Two parallel arrays have been provided. You can use the following code to get you started. //START CUTTING CODE HERE public class MichakR_PetShelter { public static void main(String[] args) { String[] breedNames = {"Bulldog", "German Shepherd", "Golden Retriever", "Beagle", "Poodle", "Boxer", "Mixed Dog", "Husky"}; int[] breedCounts = {2,5,3,1,8,1,11, 3}; //generate report //get Max Breed //print report } public…

Description This homework is in two parts. Please upload your file submissions only after you have attempted both parts. Part A - One Dimensional (1D) Arrays: Answer any one of the following using a flowchart/pseudocode: 1. Hamming numbers are also known as ugly numbers and also 5-smooth numbers (numbers whose prime divisors are less or equal to 5). Hamming numbers are numbers of the form H = 2i x 3j x 5k where i, j, k 2 2 0 Create a 1D array. The array size is provided by the user at run time. Populate the array with Hamming numbers The first few numbers of this sequence are 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 25, 27, 30, 32, 36, 40, 45, 48, 50, 54, 60..
Build Brothers company in C A civil engineering company called Build Brothers has approached you to write a program to help some of their employees with getting their job quicker specially when it comes to calculating different equations in their construction projects. Currently, they use the following PDF to perform all their calculations: http://www.madison-lake.k12.oh.us/userfiles/680/Classes/16192/IED-Review%20Engineering%20Formula%20Sheet.pdf They are willing to develop a small software to calculate all the functions and calculations in the above cheat sheet. They have made this decision to reduce inherent human errors during calculation and improve efficiency. They think that these can be achieved by an “advanced calculator” that allows a user to choose an equation, provide the inputs, and calculate the outputs. Before the company invests on the final product, the have agreed on developing a proof-of-concept first. The idea is that your solution will ‘prove’ that a better…
