- Show (in code) the 4 ways you can initialize a pointer (depending on what you want to allow to change). In each example, explain what can change and what can not.arrow_forwardIt's well knowledge that "dangling and wild pointers" are problematic for pointers. Use specific examples to back up your argument.arrow_forwardWrite a paper that summarizes the chapter (or an online resource) that may help you understand the concept of pointers. Include the following topics in the paper. Include illustrations either from the book, or an online source or your own illustration. Come up with an introduction Pointer Variable Declarations and Initialization Pointer Operators Pass-by-Reference with Pointers Built-In Arrays Using const with Pointers sizeof Operator Pointer Expressions and Pointer Arithmetic Relationship Between Pointers and Built-In Arrays Pointer-Based String About Smart Pointersarrow_forward
- What exactly is a pointer? How should a pointer be declared and initialised? Give an example.arrow_forwardWhat does it mean to have a pointer variable? What are you hoping to accomplish with it? What exactly is a dynamic array, and how does its functionality manifest itself? Where can I get more information on dynamic arrays and pointers?arrow_forwardAnswer the following as completely as possible in your own words:1. Explain how an array is sent to a function as a parameter.2. State which parameters should almost always be sent to any function which modifies an array. Explain why.3. Explain the similarity between index notation and pointer arithmetic.arrow_forward
- Pointer arithmetic. Implement the following:a. Implement a print function with array and size parameters. This function should print the array using pointer arithmetic.b. Overload the print function to accept array, size and index parameters. If the index is between 1 and size-2 inclusive: Use pointer arithmetic to print: 1. the value at index 2. the value previous to the index 3. the value after the index c. Implement a sum function with array and size parameters. This function should return sum of the array, and use pointer arithmetic.d. Implement a average function with array and size parameters. This function shouldreturn average of the array, and use pointer arithmetic.e. Use provided main function to test your functions. ( Do not change the int main the question has provided. Included a snip of the int main function. Output has to be the same as shown in the snips)arrow_forwardWhen asked, "What is a pointer variable?" What should we do now? That's because it's an array that changes on the go. Why are pointers and dynamic arrays problematic?arrow_forward.“Dangling and wild pointers are known to be problems with pointers”. Justify the given statement with the helpof suitable examplearrow_forward
- How do smart pointers work? What function do they fulfil?arrow_forwardAssignment Pointers & Classes1- Define a class student with the following fields:a. First nameb. Last namec. IDd. Number of courses enrolled ine. Dynamic array of courses (taken and currently enrolled in): String *coursesf. Dynamic array of grades: int* gradesg. Addressh. Registration feesi. Total number of creditsj. Expected Graduation term.2- Declare an array of four students. Perform the following operations using your declared array:a. Open the provided file input.txt. Fill the array by reading values from the specified inputfile. Make sure that the array of courses and array of grades are initialized properly anddestroyed properly as well.b. Call a function that prints student information in a well-organized table like fashion.c. Call a function that compares average between two students.d. Call a function that prints student names based on their GPA from highest to lowest.(hint you need to sort the array of students).e. Call a function that prints student names from lowest…arrow_forwardIn C++, how can one easily duplicate a set of shared pointers into another array? Make a list of various solutions to the situation you've been given. Is it true that copying shared pointers also copies the objects they manage? Explainarrow_forward
