Write 3 functions: Write int readNumbersIntoArray(int numbers[], int size); // Reads up to size numbers or a non-numeric and puts them in the array. // Returns how many numbers read. Write int minOrMax(int numbers[], int size, bool Max); // Returns the minimum or the maximum value in the array depending on "Max". // If "Max" is true, then it returns the maximum. // If "Max" is false, then it returns the minimum. Write double trimmedAvg(int numbers[], int size); // Returns the trimmed average of the array. // A trimmed average is a normal average but leaves out the first instance of // the smallest and largest value in the array when doing the calculation. // HINT: use calls to minOrMax() to get the largest and smallest number. Write int main(): // Prompt the user for between 3 and 20 numbers and use readNumbersIntoArray() to // read them into an array. Print an error message and exit if less than three numbers. // Print out the min, max, and trimmedAverage of the array using calls…
Hello, How can I do part 3 in c language , Part 2: Combine arrays Write a program that does the following: Creates int array array_1 of length 10. Creates int array array_2 of length 10. Takes int values from the user of for 10 values for array_1 and array_2, each. Creates a new int array array_3 which copies the values of array_1 and array_2, in interleaved order, into it. Prints out the contents of Prints out the contents of array_1, array_2 and array_3. Part 3: String / Character array Repeat Part 2, but this time use arrays of char (instead of int), and stop receiving input into array_1 and array_2 when the user hits Enter / newline and insert a Null character into the array. Here is the code that I came up with : #include <stdio.h>int main()#define MAX 10{char array_1[MAX];char array_2[MAX];printf("enter char : enter \n to stop"); printf("enter array_1 :\n");for (int i = 0; i != '\n'; i++);{scanf_s("%c", &array_1);} printf("enter array_2 :\n");for (int i = 0; i…
4. Given an array of ints, return the number of times that two 6's are next to each other in the array.int n[] = {2, 6, 71, 6, 6, 6, 34, 6, 6, 89}; C++
Java - Functions with 1D Arrays Create a program that asks the user for the size of an integer array and the elements of the array. Then, create a function called maxArray() with the following details: Parameters: An integer array The size of the integer array Return type - int Return value - the maximum value of the integer array Call the function you created in the main and pass the integer array and its size to it. Make sure to store the return value in a variable so you could print it afterwards. Input 1. First line contains the size of the array 2. Succeeding lines are the elements of an array 3. First line contains the size of the array 4. Succeeding lines are the elements of an array 5. First line contains the size of the array 6. Succeeding lines are the elements of an array 7. First line contains the size of the array 8. Succeeding lines are the elements of an array Output Enter size of array: 5 Enter element 1: 1 Enter element 2: 2 Enter…
1. single element of an array can be passed to the function? true or false. 2. Array can be declared as constant? true or false. 3. which of the following gives the memory address of the first element in array x? a. X b. X[0] c. X{0} d. X_0 e. X(0) 4. The index of the last element of array X whose size is S? a. S+1 b. S-1 c. 0 d.1000 e. S 5. Assume you have the following declarations const int MAX = 1000;double A[MAX];which of the following sentences is incorrect? a. The assingnment statement MAX = 1000 is mandatory. b. we can store up to 1000 values in the mandatory. c we cannot change the size of the array A during the runtime. d. all values in the array are set to ZERO's (0) e. all above sentences are correct. 6. The only difference between char array and string is that, the string ends with '\0'? true or false. 7. Index of an array can be of type integer or double, since both deals with the digits? True or False 8. Which definition describes the term Array precisely?…
Do the following in the most efficient way possible in C Language: 1. Take an Array of 10 integer values (automatically should be converted to ascending order). 2. Insert Values - Value should be inserted automatically as per the ascending order. If array is {1,7,28,45,67,81} and the user inserts 31; the program should automatically insert at the 3rd index and array size should increase by 1. 3. Delete Values by Range - the user will be asked to two indexes (<sizeofArray) and all values in between those indexed should be deleted. E.g. If array is {1, 7, 28, 45, 67,81} and user enters the indexes 2,4. Then the values 28, 45, 67 should be deleted.

Note: If at any time, the array becomes unsorted, then; some values need to be deleted at runtime to make the array sorted again. At any given time, the array shouldn't be unsorted. Please do not use Pointers and only use Array as a Data Structure.
Array is defined as a. None of the mentioned. b. A series of elements of the same type in contiguous memory locations. O C. A series of elements of the same type placed in non- contiguous memory locations. d. A series of elements.
The array index can be any integer less than the array size… TRUE OR FALSE
You are given an array of integers and you have to swap the first and last element of the array without using a third variable. Modify the original array and do not create a new array. Time: O(1) Space: O(1) Language: C You need not write the complete code, complete the function, void modify(int *arr, int n){ }
3. Complete the program Student Records that simulates a student records system. The program reads a list of student ids, names, and GPAS from a file exam.txt, and stores the information in parallel array lists ids, names, and gpas. Sample input (exam.txt): 132 Woody 4.1 465 Buzz 3.1 443 Rex 2.8 124 Hamm 3.3 337 Jessie 4.2 Your program will display a GPA report. You must include a method named reportByGPA (...) that accepts the required array lists and minimum GPA and displays the list of students that meet the criteria. Sample output: Enter the minimum GPA: 4.0 Students with GPA of 4.0 or higher 132 Woody, GPA: 4.1 337 Jessie, GPA: 4.2 end of program import java.util.ArrayList; import java.util.Scanner; import java.io.File; import java.io.FileNotFoundException; public class Student Records { public static void main(String[] args) throws FileNotFoundException ( Scanner f = new Scanner (new File ("exam.txt")); Scanner kb = new Scanner (System.in); ArrayList ids = new ArrayList ();…
