int x;
int* intPtr;
Write a C++ program that contains five more statements. The first statement makes intPtr point to x by using the address-of operator. The second statement dereferences intPtr and stores the value 5 into x via indirect addressing. The third statement prints the actual memory address of where the variable x is stored. The fourth prints the contents of intPtr. The fifth prints the contents of x. Show your source code and program output.
im having some trouble with this
Requirements: Write a Python script that prompts the user for the length of a side of a polygon and prints a table of areas of several polygons. Sample output is shown below. Additional requirements: • Your program should use functions to organize the code. Implement these functions: - main The main function should call the function get_side_length and then send side_length to report. - get_side_length This function should prompt the user ("Input the length of a side: ") and return side_length to main as an int. - report This function should print a heading line ("side length...number of sides...area") and use a loop to print a table of values as shown in the sample output below. The report function should call polygon_area to calculate the areas needed for the table. The function report will have to call polygon_area once for each area that it needs to print. - polygon_area This function takes num_sides and side_length as parameters and returns the…

Consider the provided C++ code in the main.cpp file:
The function func2 has three parameters of type int, int, and double, say a, b, and c, respectively. Write the definition of func2 so that its action is as follows:
Prompt the user to input two integers and store the numbers in a and b, respectively.
If both of the numbers are nonzero:
If a >= b, the value assigned to c is a to the power b, that is, aᵇ.
If a < b, the value assigned to c is b to the power a, that is, bᵃ.
If a is nonzero and b is zero, the value assigned to c is the square root of the absolute value of a.
If b is nonzero and a is zero, the value assigned to c is the square root of the absolute value of b.
Otherwise, the value assigned to c is 0. The values of a, b, and c are passed back to the calling environment. After completing the definition of the func2 and writing its function prototype, run your program.

#include <iostream>
#include <cmath>
#include <iomanip>…

- Hello, How can I store a whole book in a file in c language? I had some issues because the string is too long. here is the question: For this assignment I have uploaded a large text file that contains the entire book “Robinson Crusoe” byWilliam Defoe as file defoe-robinson-103.txt Consider the code shown below. It uses the fgets function.fgets is used to read (“get”) strings (“s”) from a file (“f”), hence the name “fgets”. It takes the following arguments:1. A pointer to an array large enough to store the string. In our case that is the char array calledbuffer of size MAX.2. The size of the array, in our case the symbolic constant MAX, set equal to 4000 in line 4.3. The file pointer of the file to read from, in our case bkPtr. Each call to fgets returns a string until the newline (“\n”) character or EOF is encountered. The codereads strings from the file defoe-robinson-103.txt in the while loop and prints them to screen.Implement this program and run it.arrow_forwardBinary Addition. Write a Python program that adds numbers together in binary. The user will be prompted to enter integers to be added and the program will output the addition result in binary. You must create a toBinary() function that converts an integer to binary. (You are not allowed to use the python bin() function). You must also create a binary Add() function that takes two binary strings and adds them together. You are not allowed to use ‘+’ or sum meaning that you must also convert the integers to binary before adding the binary strings together.arrow_forwardUsing c++ oop solve below program.Make function and call them into main function.
