Which of the following are true about arrays? Arrays are reference types. Array indexing is bounds‐checked. Arrays sometimes can be created without using new. The entire contents of an array can be copied via =.
D. The method construct will receive four parameters: an integer k, and three arrays called old1, old2, and sumarr. The method will construct the first k elements of the sumarr array fromt the first k elements of the oldi and old2 arrays, as follows. Each element of sumarr will be equal to the sum of the corresponding elements of gldi and gld2. For example, sumarri0] will be old1[0]+old2[0], sumarr[1] will be old1[1] + old2[1] and so on. (You are using parallel arrays.) Write a complete Java program to do the following: the main program will call a series of methods to process a set of data. One method will read data into two arrays. A second method will print the values stored in an array. A third method will find the smallest of the values stored in an array. A fourth method will construct a new array from two existing arrays. A fifth method will compare the values in the two arrays. Use files for both input and output. Be sure to pass the file variable to any method that will need…

Code for this in C: You have created three arrays:array A of size 100array B of size 50array C of size 200You are to store the first 100 numbers (1,2,3,...,100) into array A, the first 50 positive odd numbers (1,3,5,...,) into array B, and the reciprocal of each position [C(5) = 1/5] into array C. Then, output the contents of each array.
Can you help me please: have the program know when numbers out of the array boundaries are received and mitigate those problems. The given code intentionally induces numbers out of bounds and the student’s portion must correct for this. As always use a header file and implementation file to do those calculations. Remember not to change the given code below in any way Design and implement the class myArray that solves the array index out of bounds problem and also allows the user to begin the array index starting at any integer, positive or negative. Every object of type myArray is an array of type int. During execution, when accessing an array component, if the index is out of bounds, the program must terminate with an appropriate error message. Consider the following statements:myArray list(5);                                  //Line 1 myArraymyList(2, 13);                     //Line 2myArray yourList(-5, 9);                    //Line 3The statement in Line 1 declares list to be an…

Write a function called FindMyChar that receives three parameters: . the name of the array • the array size • a character ch The function must return the index number in which the character ch is in your array. If the character ch is not found of the array, insert ch in the last index of the array and return that index number. This index number will be printed from your main( ).

Suppose you are given a list of students registered in a course and you are required to implement an array-based student list. Each student in the list has name, regNo, department and cGpa. Implement different functions for entering the data (like constructor (for setting to default values), setName, setReg, etc.). You also need to implement the following function related to the array. insertStudent( ) : It has 2 options • Asking the user for index and then insert the student at that index AND • Asking the user for name of the student where the new student is to be added (New student should be added at the index of the student whose name is entered) o If the list is full, it should create a larger list (new size should be entered by the user), copy all the data in it and make insertion as instructed o (Insertion will only be made if the reg of the new student doesn’t exist in the list) deleteStudent( ): Same as insertStudent( ) (either by asking the index or student name) sort( ): Ask…
