**PLEASE FOLLOW THE TEMPLATE GIVEN BELOW** Develop a C++ program that reads the student’s name and scores from the attached data file “students.txt” and store them in an array of Student struct objects, then calculate and display each student’s final grade based on the following criteria: midterm exam is counted for 25% of the final grade, final exam is counted for 25% of the final grade and average of 4 labs is counted for 50% of the final grade. The format of the attached data file “txt” is --- //student name // midterm exam score, final exam score // lab1 score, lab2 score, lab3 score, lab4 score (See Attached Image 1) Expected output on screen --- (See Attached Image 2) Define a new struct data type “Student” to represent a student record. Each student’s record should be read from the data file “txt” and stored in a variable of Student struct. Create an array of Student struct with size of 24, save all student struct records in this array. Define a function “calculateGrade(…)”…
python3 programing!! Make a program that takes bets on horse races. There will be four types of bets described below. The horse race result is generated by a function a function called ReadySetgo that simply scrambles the horses into random order as a “psuedo/simulated” horse race and that tells you the race results. I will provide you with the code for your ReadysetGo function as shown above you can just call shuffle to simulate the race. We assume four horses run in a race, and we assume the horses are named by numbers 1-4. Let’s say the horses are initially in the order 1 2 3 4. If you call Readysetgo to randomly shuffle them (that’s our pseudo-race) we might get a race result of 2 1 4 3 for example, which means: horse #2 came in first, horses #1 came in second, horse #4 came in third and horse # 3 came in fourth. The user starts out with 200 dollars. Betting costs are as follows: An Exacta bet costs 10 dollars, and an Exactabox bet costing 5 dollars, a Trifecta bet costs 25…
Write in C++ Sam is making a list of his favorite Pokemon. However, he changes his mind a lot. Help Sam write a function insertAfter() that takes five parameters and inserts the name of a Pokemon right after a specific index. Function specifications Name: insertAfter() Parameters (Your function should accept these parameters IN THIS ORDER): input_strings string: The array containing strings num_elements int: The number of elements that are currently stored in the array arr_size int: The number of elements that can be stored in the array index int: The location to insert a new string. Note that the new string should be inserted after this location. string_to_insert string: The new string to be inserted into the array Return Value: bool: true: If the string is successfully inserted into the array false: If the array is full If the index value exceeds the size of the array

Recall that the result of the function is returned in ro. You will find it helpful to examine the assembly code before, during, and after the loop to form a consistent mapping between the registers and the program variables. (a) Which registers hold the values x, n, result, and mask? (b) What are the initial values of result and mask? (c) What is the test condition for mask? .__) { (d) What is the C expression that updates mask?
Create a JavaScript Arrow function that meets the following requirements: • Authored using arrow expression syntax (constant name is _replaceCharacter) • The function is passed 1 string argument • The function returns to the caller a new version of source string where: o All character occurrences that match the first character are replaced with ‘*’ o The function is case sensitive (for example ‘a’ != ‘A’) o The first character is never replaced (only subsequent characters after the first) • Console log output is NOT permitted. • The function should pass each of the illustrated examples below at a minimum

*C Programming This exercise is to help you learn how to debug compiler warnings/errors and other common errors in your code. For each part labeled P(n), there is a warning/error/problem that goes with it. Write down what the issue was in the `Error:` section of each problem. Work on `segfault.c` along with your fixes and error comments. segfault.c file // P0#include <stdio.h>#include <stdlib.h>/* Error: */ void fib(int* A, int n); intmain(int argc, char *argv[]) {int buf[10];unsigned int i;char *str;char *printThisOne;char *word;int *integers;int foo;int *bar;char *someText; // P1for (i = 0; i <= 10; ++i) { buf[i] = i;}for (i = 0; i <= 10; ++i) { printf("Index %s = %s\n", i, buf[i]);}/* Error: */ // P2str = malloc(sizeof(char) * 10);strcpy(str, "Something is wrong");printf("%s\n", printThisOne);/* Error: */ // P3word = "Part 3";*(word + 4) = '-';printf("%s\n", word);/* Error: */ // P4*(integers + 10) = 10;printf("Part 4: %d\n", *(integers +…

What's Hiding Amongst the Crowd? Language - Java Script A word is on the loose and now has tried to hide amongst a crowd of tall letters! Help write a function to detect what the word is, knowing the following rules: The wanted word is in lowercase. The crowd of letters is all in uppercase. Note that the word will be spread out amongst the random letters, but their letters remain in the same order. ● Examples detectWord("UcUNFYGaFYFYGtNUH") → "cat" detectWord("bEEFGBuFBRrHgUHINFYaYr") → "burglar" detectWord("YFem HUFBbezFBYZF BYLleGBYEFGBMENTment") → "embezzlement"
