Instructions: You are strictly not allowed to use anything other than pointers and dynamic memory. One function should perform one functionality only. Task 1 Write a program in C++ that reads data from a file. Create dynamic memory according to the data. Now your task is to perform the following task. Row wise Sum Column wise Sum Diagonal wise Sum Example data.txt 4 5 1.6 10.2 33.7 99 20.5 3 44 50 96.1 2 8 9 4 74 50 99 19.1 Output: Sum row wise: 165, 191, 17, 242.1 Sum col wise: 127.6, 120.1, 228.8, 118.1, 20.5 Sum diagonal wise: Not Possible Note: You are restricted to use pointers and your function should be generic. Avoid memory wastage, memory leakage, dangling pointer. Use regrow or shrink concepts if required.
In C++, When an array is passed to a function as a pointer, the function doesn't know the size of the array. List 3 ways to handle this problem.
Programming language: C++ Implement a function named insert that takes a dynamically allocated array of ints, the array’s length, the index at which a new value should be inserted, and the new value that should be inserted. The function should allocate a new array populated with the contents of the original array plus the new value inserted at the given index. The originally array should be freed. The following sections provide a detailed description of this function: Make sure your source code is well-commented, consistently formatted, uses no magic numbers/values, follows programming best-practices, and is ANSI-compliant. It is expected to have the program output
Which of the following statements is NOT correct? Group of answer choices C++ language provides a set of C++ class templates to implement common data structures, which is known as Standard Template Library (STL); In STL, a map is used to store a collection of entries that consists of keys and their values. Keys must be unique, and values need not be unique; In STL, a set is used to store a collection of elements and it does not allow duplicates; Both set and map class templates in STL are implemented with arrays.
use Advanced C++ techniques, containers and features to refactor the C/C++ algorithm. The purpose is toreplace appropriate declarations and code segments with Advanced C++ declarations and code. * Replace all arrays with appropriate STL containers. * Use STL algorithms to REPLACE existing logic where appropriate. * Use smart and move pointers where pointers are needed. * Use lambda expressions where appropriate. * Use C++ style casting when needed. * Look for opportunities where tuples could be used. * The code listing is in C and C++. If you don't understand someof the C code or C functions, please google. If there are logic or syntax problems, please fix. int Algorithm(int a[], int x, int y) { int p, i, j = x; p = y; for(int i=x; i < y; i++) { if(a[i] < a[p]) { swap(&a[i], &a[j]); j++; } } swap(&a[p], &a[j]); return j;}
In C++ Create an array of head pointers, statically allocated of size 101 of that type: Now, create a pointer that can point to the first element: Show how to dynamically allocate an array of 101 elements of head pointers: Write the code to initialize each element to NULL: Rewrite the code to initialize each element to NULL using pointer arithmetic:

Giventhe following C program that contains struct student, that has name and age, and a pointer to struct student *ptr, but does not assign a value to it: 1. What gdb commands would you use to find the error it contains? #include <stdio.h> /*write program Then, print ptr->age*/ //make struct student struct student { charname[25]; int age; }; int main() { //declare pointer to struct student struct student *ptr; //print ptr -> age printf("%d", ptr->age); return0; }
In c++, please and thank you! Write a function that dynamically allocates an array of integers. The function should accept an integer argument indicating the number of elements to allocate. The function should return a pointer to the array.
Please Help In JAVA Here is the skeleton of a code for insertion sorting in an imperative language. You have to add right lines of codes for the language you choose (C, C++, C#, JAVA etc,). The following sample is for C++. #include <iostream>#include <array>#include <stdio.h>#include <stdlib.h>#include <ctime>using namespace std; void insertionSort(int A[], int n){for (int i = n-2; i >= 0; i--){ int j; int v = A[i]; for (j = i + 1; j <= n-1; j++) { if (A[j] > v) break; else A[j-1] = A[j]; } A[j-1] = v;}} int *randomArray(int n){srand((unsigned) time(0));int * A = new int [n];for (int i = 0; i < n; i++){ A[i] = rand();}return A;} Sample function calls (call these functions in main driver function):int n = 100000;int * A = randomArray(n);insertionSort(A, n);delete [] A; Note: delete memory of first array before sorting second array. After you modify the code: (1) Generate 100, 000 random numbers and sort them (2) Generate 300000…
Write a C++ source code that utilizes the generation of random numbers to make sentences.The program must utilize four arrays of pointers to the character called article, noun, verb,and preposition. The program ought to make a sentence by choosing a word aimlessly fromeach array in the accompanying order: article, noun, verb, preposition, article, and noun. Aseach word is picked, it ought to be connected to the previous words in a cluster that issufficiently huge to hold the whole sentence. The words ought to be isolated by spaces. At thepoint when the last sentence is yield, it should begin with a capital letter and end with a period.The program ought to create 20 such sentences
in c++ Write a function named “countTheSameAsLast” that accepts an array of pointers to Name objects and its array size. It will go through the array and return how many elements (int) in the array are the same as the last element and whether the first and the last elements are the same or not (bool). Please note that the objects pointed by elements in the array can be either Word or Item objects. Please show how you test with the list of mixed objects.
