How would a function given p by value be able to change the contents of x?

C++

The distinction between void and NULL pointers is as follows: Make use of appropriate examples to support your response.

Write a c++ function that accepts an array of doubles and the array’s size as its only arguments. The function should use dynamic memory allocation to create a new array that is double the size of the argument array. The function should copy the contents of the argument array to the second half of the new array and initialize the first half of the new 0s. The function should return a pointer to the new array. So, if the original array contained 1 2 3 4, the new array should contain 0 0 0 0 1 2 3 4. So, if the original array contained 1 2 3 4, the new array should contain 0 0 0 0 1 2 3 4.

WRITE A PROGRAM IN C++ You work for an loan analytics organization have been tasked with writing a program that simulates an analysis of loan applications. Code a modular program that uses parallel arrays to store loan application credit scores (values generated between 300 and 900), score ratings (poor, fair, good, very good, or exceptional based on credit score) and loan status (approved or declined applications based on credit score). The program must do the following: The program must first ask the user for the number of loan applications that will be in the simulation. This must be done by calling the getNumLoanApplications() function (definition below). After the input of the number of accounts, the program must use loops and random numbers to generate the credit score, score rating, and application result for each loan application in parallel arrays. These arrays must not be declared globally (major error).  The following arrays must be declared and populated: creditScores[]…

Lab 09 Understanding C++ pointers Assume p1, p2, and p3 are pointers to integer numbers. As an example, consider int n1 = 33; int n2 = 11; int n3 = 22; You are asked to implement the function void arrangelnOrder(int* p1, int* p2, int* p3) The function's goal is to order the data referenced by the pointers in such a way that after the function is called, p1 points to the smallest and p3 points to the largest of the three values. Test your function using the following main() method. Make sure your app works for all possible combinations of integer values referenced by the pointers. int main() { int n1 = 33; int n2 = 11; int n3 = 22; cout << "Before the call. n1=" << n1<< ", n2="<< n2 << ", n3=" << n3 << endl; arrangelnOrder(&n1, &n2, &n3); cout << "After the call. n1=" << n1 << ", n2=" << n2 << ", n3=" << n3 << endl; } It should produce the following output. Before the call. n1=33, n2=11, n3=22 After the call. n1=11, n2=22, n3=33 NOTE. Do not copy the data value into an array/vector and…

In C programming, if the return type of a function is Void how can you implement assert statements?  For example, Void ceasar(int n, char*x); //if char = c and n = 3 output == f  how do i use assert statements as this does not work assert (caesar(3,c)==f);

Write a C++ program with two user defined functions. The first function named "functionWithArray" takes two user input arguments of character types and return True if first argument is smaller than the second argument (alphabetically) and returns False otherwise. Write the second function named "functionWithPointers" which behaves like the first functions but uses pointers to receive the arguments. You may assume that both character arrays contain only lower-case letters, and no blanks or other non- alphabetic characters. Write a suitable Main function to test these two functions. Sample Output: Enter First String: C++Programming Enter Second String: JavaProgramming According to functionWithArrays: 'c++programming' is smaller than 'javaprogramming'. According to functionWithPointers: 'c++programming' is smaller than 'javaprogramming'.

I need help with this in C++: Write a pair of functions countEven(int *, int) and countOdd(int *, int) which receive an integer array and its size, and returns the count of even or odd numbers in the array.

need help in C++ Problem: You are asked to create a program for storing the catalog of movies at a DVD store using functions, files, and user-defined structures. The program should let the user read the movie through the file, add, remove, and output movies to the file. For this assignment, you must store the information about the movies in the catalog using a single vector. The vector's data type is a user-defined structure that you must define on functions.h following these rules: Identifier for the user-define structure: movie. Member variables of the structure "movie": name (string), year (int), and genre (string). Note: you must use the identifiers presented before when defining the user-defined structure. Your solution will NOT pass the unit test cases if you do not follow the instructions presented above. The main function is provided (you need to modify the code of the main function to call the user-defined functions described below). The following user-defined functions are…
