You want a function which takes an array of integers and n specifying the length of the array and prints a randomly selected element in the arra Function skeleton given below. Your job: complete the body of the function. You may assume that srand(time(NULL)) has been previously called when the function is invoked. // n is the length of array a[] void display_random_elem (int a[], int n) { }

Description of the assignment: Your program should read in a set of grades (that are all integers) entered by the user. The user will signify the end of the list of grades by entering -999. Do NOT process this value. You can assume that the user will enter at least three grades and not more than 100 grades, all of which will be integers in between 0 and 100, inclusive. For the set of grades, your program should compute the minimum value, print this out to two decimal places and remove it from the data. Then your program should compute the maximum value, print it out to two decimal places and remove it from the data. Then, your program should calculate the mean and standard deviation for the remaining set of grades, and print these out to two decimal places. Finally, a histogram for this data (without the highest and lowest grades) should be printed out as well. Your program should include the following functions: void readGrades (double grades [], int *n); /* This function reads an…
Which one of these functions will always return the highest number stored in the array passed to it? static int max(int[] a) int m = a[0]; for (int num : a) if (num > m) m = num; max - m; } static int max (int[] a) { int m = a[0]; for (int num: a) if (num > m) return num; return m; static int max (int[] a) int m = a[0]; for (int num : a) if (num > m) m - num; return num; static int max(int[] a) { int m; for (int num : a) if (num > m) m = num; return m; } static int max (int[] a) { int m = a[0]; for (int num : a) if (num > m) m = num; return m;
Create a function named "onlyOdd".The function should accept a parameter named "numberArray".Use the higher order function filter() to create a new array that only containsthe odd numbers. Return the new array.// Use this array to test your function:const testingArray = [1, 2, 4, 17, 19, 20, 21];

Write the statements to do the following: write a prototype for your function in the previous problem write a main function which includes the following steps declare two arrays of ints with 25 elements each prompt the user and read values into both arrays call your function from the previous problem print both arrays
///////1/////. Given an array of integers, write a PHP function to find the maximum element in the array. PHP Function Signature: phpCopy code function findMaxElement($arr) { // Your code here } Example: Input: [10, 4, 56, 32, 7] Output: 56 You can now implement the findMaxElement function to solve this problem. Let me know answer. //. .
Given an integer array of positive single digit values such as:int a[] = {8,4,2,6,9};1) Write a recursive arrayToN function which returns the concatenation of all array values as an integer value.This function should accept all required data as parameters and return a long integer value.ExamplesIf the array is 8 4 2 6 9 the arrayToN function returns the integer 84269.If the array is 0 2 6 8 9 3 5 1 the arrayToN function returns the integer 2689351.
Prompt: In Python language, write a function that applies the logistic sigmoid function to all elements of a NumPy array.

In C++ please ! Write a Program that: Initializes an interger array size of 10 with random intergers in range [10,30]. Use a function named 'initialized_array' to acheive that. Determine if all array elements are distinct from each other or not.Use boolean function named 'distinct_elements' to achieve that function 'distinct elements, if the elements in the array are duplicate print out, elements are duplicate if not print out array

4. Arrays. In order to test the functions in this question, you will need an array. We can create a three- dimensional test array as follows: testArray xijk - máx rij,k i=1 i=1 i=1 (b) Now suppose we want a function testFn2 which returns the d2 x d3 matrix {zj.k} where di Zj,k = Σ i=1
What is a nested function? and what part in the following code is considered a nest function?? int main( ) { Begin:arraysize= readNum() Ok=verifySize(arraySize) if (ok==1) creatArray(array-size) else Go to Begin printArray(arraySize) reverseArray(arraySize) printArray (arraySize) } // ------------------------------------------------------------ int readNum() { input an integer return the integer to main program } // ------------------------------------------------------------ int versifySize( int arraySize) { if (0<arraySize< 20) return 1 else return 0 } // ------------------------------------------------------------ void…
