Question
completing the following:
Program : Create a C++ program that asks the user to enter three integer values as input. Store the values into three different variables. For each variable, create an integer pointer to dynamic memory. Display the contents of the variables and pointers. In your program, be sure to use the new operator and delete operators to management memory.- Program Analysis: Given your program implementation, discuss and identify the possible security vulnerabilities that may exist. If present, discuss solutions to minimize the vulnerabilities. Discuss and identify possible problems that can result in errors when using integer pointers. Your analysis should be 1-2 pages in length.

- 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.arrow_forwardBuild a C program that performs the following operations: Declares three pointer variables called iPtr of type int, cPtr of type char, and fFloat of type float Declares three new variables called iNumber of int type, fNumber of float type, and cCharacter of char type Assigns the address of each non-pointer variable to the matching pointer variable Prints the value of each non-pointer variable Prints the value of each pointer variable Printer the address of each non-pointer variable Prints the address of each pointer variablearrow_forwardCreate a c ++ program keeping in mind the concepts about Pointers (Pointers). Instructions: Write a program to find the maximum of a set of integers within an array. The program should ask the user to enter each of the values. At the end the program prints a pointer to point to the maximum value. The example is shown in the image Note create the program in c ++arrow_forward
- There's this house I want to buy just right around the corner. I know its address but I don't know its value. Can you please help me determine it? Instructions: In the code editor, you are provided with an initial code which has main() function. In the main(), the user is asked for an integer input and then its address is assigned to a pointer variable (see line 10) Your task is to print the value of the pointer variable using the dereferencing operator.arrow_forwardGive an example of a function with two arguments and statements that are executed when the function is called. -Provide details about the return statement and the purpose of your function. -Provide an example of an array and a vector. -Describe your experience using GitHub, GitLab, Git, or other versional control software in general. Explain what aspects of the GitHub process you are comfortable with and what areas you need more practice or help.arrow_forward
