In C++, the first element of the array is referenced as array[0]. Explore the web and find the history of this choice. Some languages and packages like MATLAB start the indices from 1. That is, the first element of the array is referred to as array[1] not array[0]. If you were the creators of C++, which of the conventions for the array indices would you chose? Starting from 0 or 1.

2. fast please in c++ If an array is already sorted, which of the following algorithms will exhibit the best performance and why? Be precise in your answer. Selection Sort Insertion Sort Merge Sort Quick Sort

C program Andrew practices programming a lot and recently he came across the topic of pointers. He wondered if he could use pointers to print all prime numbers from an array? Could you help him by writing a C program which takes input in an array and uses a pointer to find and print all the prime numbers from the array.   Sample Run:   Input: 1 2 3 4 5 Output: 2 3 5

Python lists are commonly used to store data types. Lists are a collection of information typically called a container. Think of a physical container that can hold all kinds of objects, not just one object of the same type. Python includes a built-in list type called a list. They can be managed by many built-in functions that help fill, iterate over, add to, and delete them. Why is it useful to store information with different data types? When do you choose to use a list over a dictionary? Provide a code example that supports your comments.

Material Java/ C++/C- language Personal Computer. Instructions: A. Matrix Addition C. Matrix Transpose 1. The transpose of an m x n matrix A is n x m matrix AT. 2. Formed by interchanging rows into columns and vice versa. 3. (A¹)kj = Ajk 4. Let m input to enter the number of rows in the Matrix. 5. Let n input to enter the number of columns in the Matrix. 6. Display the transpose matrix 7. Save the file TRANSPM Questions: 1. What do you mean by an array? 2. Differentiate between for loop and while loop. 3. Define transpose of matrix? What will be the order of the matrix AT, if the order of the matrix A is 4 x 4.

Make a program in C language of the following: 1. Make a tic-tac-toe game using 2D array. Please do the above using the most simplest and efficient way possible. No use of Pointers Please.

How difficult is it to duplicate a collection of shared pointers into another array while using the C++ programming language? Create a list of the several approaches you may use to tackle the issue that has been presented to you. Is it the case that copying a shared pointer also copies the objects that it controls? Explain

Use C Language Pascal’s Triangle Version 2   The Pascal triangle can be used to compute the coefficients of the terms in the expansion  (a + b)n. For example, (a + b)2 = a2 + 2ab + b2 where 1, 2, and 1 are coefficients. Write a C program that creates a two-dimensional matrix a representing the Pascal triangle of size n. For example, a Pascal triangle of size 10 is shown below:

Please answer the above question in python programming language

Oops! I had some typos in that last questions.The input/output examples were wrong In the C(89) standard of C programming languageSuppose you are given an array of integers. You want to insert a number x to the array and rearrange so that all the elements are less than or equal to x are before x, and the elements after x are greater than x. For example, suppose the list is {3, 2, 7, 0 1, 5} and x is 4, since 3, 2, 0, and 1, are less than or equal to 4, 7and 5 are greater than 4, the new array is {3, 2, 0, 1, 4, 7, 5}. The new array has the length of n+1 where n is the length of the input array.Example input/output #1:Enter the length of the array: 10Enter the elements of the array: 3 5 1 4 0 3 9 2 8 11Enter the number for insertion: 3Output: 3 1 0 3 2 3 5 4 9 8 11Example input/output #2: Enter the length of the array: 8Enter the elements of the array: 5 0 13 4 1 7 3 5Enter the number for insertion: 6Output: 5 0 4 1 3 5 6 13 71) Name your program arrays.c2) Include the rearrange( )…

How easy is it to copy a set of shared pointers into another array in C++? Make a list of different ways to solve the problem you've been given. Is it true that when you copy a shared pointer, you also copy the objects it controls? Explain

C+++ proram An organization is going to design a small database to store the records of students. They hire you in the development team and assign a small module of the project. You have to store the firstName, LastName, address, sapId, semester, and CGPA of all the students in a class. You are supposed to use 2D character array to store firstName and lastName. To test the working of your module you can fix the class size to 15. Pass these arrays into a displayRecord function which display complete information of all the students in a class. Create a function updateRecord which receives the sapId and search that whether this sapId exist in the array. If it exists than change the firstName, address and CGPA of that student otherwise display a simple message that "record does not exist
