THE THIRD JAVA PROGRAM C) Describe and then Write a multithreading program that searches or try to calculate a mathematical function of your choice based on the two-dimensional array. Hints: 1) To calculate the execution time of the program you can use the System.currentTimeMillis() to obtain the current time before and after the execution of the algorithm and subtract the earlier time from the latter to get the total execution time

Need help making C or java code for these steps : Assume there are N=1,000 people in the small place. Use a simple array to record the status of each person, call it “infected”. For example, infected[1]=TRUE if user 1 is infected. Each infected individual may come into contact with ratio of all people in each round of infection. Each contact between an infected individual and a healthy individual has a chance of that the healthy individual will be infected.
answer this using c++ Part 1: Write a function that receives, as arguments, a pointer to a double array, as well as the number of elements in the array (int). The function must use pointer operations (no block notation such as arr[i]) and calculate the standard deviation of the elements in the array. The function returns the standard deviation to the calling statement. Due to possible rounding or floating-point arithmetic errors, round the result to 4 decimal places. Use the formula below. Each summation can be done with a for-loop. To calculate the square root you may use the <math.h> header file. You may use the following code: float data[] = {11.2, 2.4, 3.13, 16.4, 5.8, 9.22, 4.9, 10.5, 6.5, 2.99}; int N = sizeof(data) / sizeof(float); Part 2: Write a function that receives, as arguments, a pointer to a double array, as well as the number of elements in the array (int).

2. Task 1: Using Single-Dimensional Array Write a C program that will accept 10 input values and will store the values in array. The program will also identify and print the minimum, maximum and average of input values. NOTE:Your source code must display any of the given sample output below.It means your source code should be flexible enough to meet any of the given sample output.Your source code output must be identical to any of the given sample output.It means you have to strictly follow what are the displayed text, labels, casing of characters in the sample output. OUTPUT 1: Input Value 1: 50 Input Value 2: 20 Input Value 3: 35 Input Value 4: 100 Input Value 5: 75 Input Value 6: 89 Input Value 7: 5 Input Value 8: 11 Input Value 9: 85 Input Value 10: 60 MIN Value: 5 MAX Value: 100 AVG Value: 53 OUTPUT 2: Input Value 1: 10 Input Value 2: 9 Input Value 3: 8 Input Value 4: 7 Input Value 5: 6 Input Value 6: 5 Input Value 7: 4 Input…

(C PROGRAMMING ONLY) 1. Spell-it-out!by CodeChum Admin Are you intimidated with complicated words? Don't be! The trick is to break it down letter by letter! Let’s create a program that prints out the character in the array index indicated by the input integer. For example, if the array has 3 character elements, 'j', 'r', and 'd', and the inputted integer value is 1, then we print 'r' because 'r' is found at index 1. Instructions: In the code editor, you are provided with an array of characters (or a string).Your task is to ask the user for an integer input which represents the index and then print out the character of the string found at that index.Input 1. Index of the array Output Enter the index: 4r
QUESTION 4 ( java programming) (a) Declare two arrays as below and display all the values of the arrays using two for loops starting with Array1 followed by Array2. Next, display the first element of Array1 and the last element of Array2. Array1 = 15,12,4,5,2,71,8,20,1,6Array2 = 21,4,9,16,2,12,14,53,10,3(b) Declare an array named addOne and initialize it with 5 integer values. Add one to each of the 5 integers and display addOne after adding 1.
Language: C Reverse the elements of an array using pointers. To this end define the function void reverseArray (int* array , int arraySize). Inside the function, declare two int * pointers, one initially pointing to the first element in the array, the second one pointing to the last element in the array. Swap the values in the array indicated by each of these pointers. Increment the first pointer and decrement the second pointer. Repeat the process you reach the middle of the array. Print your original, and the reversed array. Problem 2.

NEED HELP WITH C++...PLEASE PASTE INDENTED CODE PLEASE USE pointer arithmetic METHOD TO ANSWER Write a function definition for a function named getNeighbors to do the following: 1. Accept an array of integers, the size and an index as input parameters. 2. Return a new dynamic array of size 2 which contains the elements before and after the original index. 3. If the provided index would access an area outside of the array, store 0,0 instead. Example 1: Original array is 100 5 25 34 8 with an index 3. New array would be 25 8. Example 2: Original array is 100 5 25 34 8 with an index 0. New array would be 0 0 since before would be -1 which is an invalid index.
