- Define the term " pointer to void " .Note: Don't use functions AND pointers.Minutes(using Pointers) by Catherine Arellano Write a program that will accept an integer value from 0000 to 2359. It will then extract the first 2 values of the integer to be the hours, and the last 2 to be the minutes. Implement the following functions: void extracts(int* time, int* hour, int* min); /* extract the hours and minutes from the time and stores the result to the address of hour and min respectively.*/ void display (int* hour, int* min); /*display the hours and minutes*/ Note: You are not allowed to edit main.c and Time.h. Input A time in format HHMM 1430 Output Hours and minutes Hour: 14 Minutes: 30 main.c Time.h 1 #include 2 #include "Time.h" 3 int main(void) { M456909 7 8 } int time, hour, min; scanf("%d",&time); extracts (time, &hour, &min); display (&hour, &min); return 0;
- Pointer Activity You do not need getopt for this program as there are no arguments. Call the executable pointers. Create variables for a character, a string, an integer, and a floating point number. Create pointers for each of those variables. Ideally, use the same name as the variable but add a p in front of the name. (For example: (total and ptotal) Ask the user to enter information for each of these variables one at a time. For each variable tell them what they should enter. (For example: “Enter a single character” or “Enter a floating point number”) Read in the information and put it in the variables. Make each pointer point to the respective variable. Print out values for the four variables without using the variables themselves. Only use the pointers. In addition print out the addresses of the memory locations that each pointer points to. You can use %p for that. Output should look like the bottom sample. Copy and paste the code and the output into a Word document and submit.…Decide which of the following statements is either true or false and re-correct the false ones. 5. do … while repetition statement gives full control on the code block to be repeated. 6. All binary operators except for the assignment operators are evaluated from Left to Right 7. A ragged 2D array is a 2D array in which each column may contain different number of rows. 8. Each row in a 2D array could be dealt with as 1D array. 9. The following statement creates and initializes the array x: int x[] = {10, 20, 30, 40, 50}; 10. A Java program may contain more than one method with the same signature.3- It is not possible to change the value of the pointer. (True or False). 4- If the following lines of code have errors, correct them; otherwise, write "no errors." for (int i=2; i<5; i++) { int s=1*2; } cout << s; 5- A function cannot be called from inside another function. (True or False). 6- How to make a function return multiple values? 7- Every class member is by default. (public, private, not public nor private) 8- Create an instance of the following class and call its methods. class Exam{ int grade; public: void seta (int b) (grade=b; } int geta () {return grade; } 9- When the word const is put before the variable definition, what does that mean? 10- How to concatenate two strings in C++ language?

- C++ Array Expander -Just do everything in main and make sure you comment each step Use Pointer Notation for the function and within the function. Use a main function and return the pointer from the ArrayExpander function to mainUSE SIMPLE PYTHON CODE PLEASE 1) Basic version with two levels of processes (master and slaves)One master process aggregates and sums the result of n slave-processes where each slaveprocess sums a different range of values in an array of 1000 random integers (please program to generate 1000 integers to populate the array).The number of slave-processes is a parameter which the user can change. For example, if the user chooses 4 slave processes, each slave process will sum 1000/4 = 250 numbers. If the user chooses 3 slave processes, the first two may each sum 333 numbers and the thirdslave process sums the rest 334 numbers.2) Advanced version with more than two levels of processesThe master process creates two slave-processes where each slave-process is responsible to sum half segment of the array. Each slave process will fork/spawn two new slave-processes where each new slave-process sums half of the array segment received by its parent. Each slave process will return the subtotal to…program Credit Card Validator - Takes in a credit card number from a common credit card vendor (Visa, MasterCard, American Express, Discover) and validates it to make sure that it is a valid number (look into how credit cards use a checksum) - it's a C++ program so use #include <iostream> - And please use an array, use files, and use pointers in this program. -
- C++ Programming. OVERVIEW OF DATA STRUCTURES. Task: Write a program to process a data array. Execute a custom task as a separate function or method of a custom class. When performing a task, use functional methods for manually entering array elements, generating random numbers, and printing array elements. Given an array of size N. Create a function to determine the element that is furthest from the arithmetic mean of the array elements (that is, the maximum absolute difference).True/FalseIndicate whether the statement is true or false. 1. When you pass an array to a function, the computer passes the address of each of the array elements. 2. When an array is sorted in descending order, the first element in the array contains the smallest value and the last element contains the largest value. 3. The variables in an array are referred to as elements of the array. 4. Assigning initial values to an array is not required, but considered good programming practice. 5. Parallel arrays are two or more arrays whose elements are related by their position in the arrays. 6. You should not pass a one-dimensional array to a function. 7. Passing an array by reference is more efficient than passing it by value. 8. The quick sort algorithm provides a quick and easy way to sort the items stored in an array, as long as the number of items is relatively small—for example, fewer than 50. 9.…Assignment: Write four different functions: a) void SelectionSort(Data *A, int N), where A is the array and N is number of data in the array. Data is the datatype, which you can declare first as a global declaration, by using typedef int Data; This helps by changing the datatype of the data to be sorted easily. b) int Min(Data *A, int start, int N); // this will retun the index min, for the smallest data from the data set A[start] to A[N-1] c) void InsertionSort(Data A, int N): d) void PrintArray(Data * A, int N); // when called this function will display all the data in the array A Also, write the driver function (i.e. the main), main should do the following: i) Declare the array dynamically, so that memory can be used efficiently. To declare an array dynamically, the following steps may be used: • Declare a pointer of type Data Data * A; • Declare number of data N, and read a value for N • Allocate memory A = new Data [N] ii) Prompt the user to enter N number of data, and store those…
