For each of the following, write a single statement that performs the indicated task. Assume that long integer variables value1 and value2 have been defined and that value1 has been initialized to 200000.
a) Define the variable lPtr to be a pointer to an object of type long.
b) Assign the address of variable value1 to pointer variable lPtr.
c) Print the value of the object pointed to by lPtr.
d) Assign the value of the object pointed to by lPtr to variable value2.
e) Print the value of value2.
f) Print the address of value1.
g) Print the address stored in lPtr. Is the value printed the same as the address of value1?

- 1: This program demonstrates the use of pointers. What is the output of this program? Assume we know that the initial address of x is 0012FF44. #include <iostream> using namespace std; int main() { int x=25; int *ptr; // pointer ptr=&x; cout<<x<<endl; cout<<*ptr<<endl; cout<<ptr<<endl; //Now we assign 100 to x *ptr=100; cout<<endl; cout<<"Now we assign 100 to x:"<<endl; cout<<x<<endl; cout<<*ptr<<endl; cout<<ptr<<endl; return 0; } Write down the output:arrow_forwardThe input string is provided as a parameter to the compress_string function. The Task: Create a reference to a function that accepts an integer argument and returns an array of pointers to functions that accept one input, a string, and return an integer.Whew! You have to read the specification at least three times to realise you don't comprehend it.How do you handle such complication?

You have to read the specification at least three times to realise you don't comprehend it.How do you handle such complication?arrow_forwardWrite a program in C++ 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.arrow_forward
- Create a program in C as follows:- Declare four floats as a1, a2, a3 and a4- Create a menu as follows:Option T to ask the user for and assign values to each of a1, a2, a3, and a4.Option V to call a function named cat that has four pointers of type float as parametersand no return. The function will sort, in ascending order, the values in a1, a2, a3 and a4.Option B to call a function named mouse that has four pointers of type float asparameters and no return. The function will sort, in descending order, the values in a1,a2, a3 and a4.Option K to call a function named dog that has four floats as parameters and no return.This function will print to the screen each of the values in a1, a2, a3 and a4 in aformatted manner (right justified with a field width of 12).Ex:a1 = 23.65a2 = 99.22a3 = 1.56a4 = 0.50Option X to exit the program.arrow_forwardWrite a C++ program that asks for two lowercase characters. Pass the two entered characters, using pointers, to a function named capit(). The capit() function should capitalize the two letters and return the capitalized values to the calling function through its pointer arguments. The calling function should then display all four lettersarrow_forwardThere'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_forward
- A pointer variable is what? Then what? A dynamic array is a What's the deal with dynamic arrays and pointers?arrow_forwardIn C++build a program to read that data with the following promptsa-) Create a class “name” with two data members: one for the first name (String) and one for the surname (String). The last name must be a pointer to char, the first name construct it as you prefer.b-) Create a grade class to store a subject name (String) and a grade (floating).c-) Create a class "student" that inherits from the class "name" and by composition can store the student's grades (consider that the maximum possible grades will be 6).d-) Create a group class to store the data of several students (consider a maximum of 10 students)e-) Develop a method that returns the average of the group of students.f-) Develop a method that returns the average of a student given his name and surname.g-) Develop a method that returns a list of students who have failed a subject (less than 6.0 points) given the name of the subject.h-) Develop a method that returns the first and last name of the student with the lowest…arrow_forward1. Write a function called displayCodes to receive the pointer of the first element of the array and the numberof elements in the array.Call the function displayCodes from the main function. 2. Write a function called displayLocations to receive a pointer to the address of the first element of the arrayand the number of elements in the array. Display the number of each item and their location in a morereadable format in columns as shown in the screen shot below.Call the function displayLocations from the main function.arrow_forward
- Which of the following types of people has limited movement and so cannot utilise pointers? I'd want to know why you're saying that.arrow_forwardWhen should a pointer parameter p be a reference parameter? Group of answer choices When the function changes p, and you do NOT want the change to affect the actual pointer argument. When the function changes p, and you want the change to affect the actual pointer argument. When the pointer points to a large object. When the function changes *p, and you do NOT want the change to affect the the object that is pointed at. When the function changes *p, and you want the change to affect the the object that is pointed at.arrow_forwardThe following code C++ uses pointers and produces two lines of output. What is the output? int v1 = 10; int v2 = 25; int* p1 = &v1; int* p2 = &v2; *p1 += *p2; p2 = p1; *p2 = *p1 + *p2; cout << v1 << " " << v2 << endl; cout << *p1 << " " << *p2 << endl; find line 1 and 2.arrow_forward
