- - Write a java program that contains a two-dimensional array of 2 rows and 3 columns. Find the sum of each row in the array, trace the code using a tracing table. - Note: No two students can try the same inputs. - You should submit the code and the tracing table in a handwritten pdf file. - Also, you should submit the code and a screenshot of the output using a word file. Tracing Table may look like the following table: Line# i j Array[0][0] Array[0][1] Array[0][2] Array[1][0] Array[1][1] Array[1][2] rowSum Output …….arrow_forward8. using c++, Write a function method that determines the mean of all the values in an array of integers. Your mean function should call a separate function that you write that determines the sum. Don’t use built-in sum or mean gadgets, but roll your own.arrow_forward- in this exercise, please do not include and use string class. The function is using only array notation and manipulation.- string functions such as strlen is not allowed.- it should not have multiple return statements in the same function- there should be no global variable.- the function should not traverse the arrays more than once (e.g. looping through the array once only) A C++ PROGRAM named "isTheLastNumberTheMax" that accepts an array of integers and its size. It will return true if the last number in the array is the maximum number in that array and false otherwise. In addition, it also returns another boolean to indicate whether this list contains more than one maximum value.For example, if this is called with the array of {10, 20, 30, 40, 50}, it will return true and falseIf this is called with the array of {50, 10, 20, 30, 40, 50}, it will return true and true. A C++ PROGRAM named "changeCase" that takes an array of characters terminating by NULL character (C-string) and…arrow_forward
- Indicate true or false for the following statements: a. Every element in an array has the same type. b. The array size is fixed after an array reference variable is declared. c. The array size is fixed after it is created. d. The elements in an array must be of a primitive data typearrow_forwardCan you explain the memory allocation of a dynamic array?arrow_forwardWriting code using the Racket language. can anyone provide an explanation on how to write a racket code using the "advance student" language? let's say you want to print out the product of numbers in an array. how would we write the code using just the basic built-in or standard functions of the racket language such as:car, cdr, null, null?, first, rest, if, define, and, or. please provide snapshots of your code as well.arrow_forward
- The following is the difference between void and NULL pointers: Use relevant examples to back up your statement.arrow_forwardFinish the swap function below using pointers and write the call to swap in the reverse function using the address of the array positions array[i] and array[size-i-1].using pointers. DON'T FORGET TO DECLARE THE PARAMETERS in the function. (Hint: if you can't figure it out with pointers, do it with the references #include <iostream>using namespace std; // Function to swap two ints using pointers// @param pointer to an int// @param pointer to an intvoid swap( ) {// TODO: Add code that swaps two integers using pointers } // Function to reverse arrayvoid reverse(int a[], int size) {for (int i = 0; i < size/2; i++) {// TODO: write the call to swap in the reverse function using the // address of the array positions array[i] and array[size-i-1].arrow_forwardWhat are the errors in the following code?arrow_forward
