- What occurs when using the ref or out keyword with an array parameter?arrow_forwardDeclare a char array named delimiters and initialize it with the comma and semicolon characters.arrow_forwardThis class will allow a user to enter 5 scores into an array. It will then rearrange the datain descending order and calculate the mean for the data set.Attributes: data[]— the array which will contain the scores mean — the arithmetic average of the scoresMethods: Average — the constructor. It will allocate memory for the array. Use a forloop to repeatedly display a prompt for the user which should indicate that userCopyright © 2019 Pearson Education, Inc., Hoboken NJshould enter score number 1, score number 2, etc. Note: The computer startscounting with 0, but people start counting with 1, and your prompt should accountfor this. For example, when the user enters score number 1, it will be stored inindexed variable 0. The constructor will then call the selectionSort and thecalculateMean methods. calculateMean — this is a method that uses a for loop to access each scorein the array and add it to a running total. The total divided by the number ofscores (use the length of the array),…arrow_forward
- Please write your own original code. Objective Create a program that initializes and works with string variables. Create a program named LastnameFirstname15.c, that does the following: Note: There is no user input for this program. Declare and initialize a char array that stores your first name in title case. Title case means the first letter is uppercase and the rest is lowercase. Ensure the size/length of the array is equal to the length of your name plus the null character.As an example, my first name is Edward, therefore the size of the array will be 7.char firstname[7] = "Edward"; Declare and initialize another char array that stores your last name in title case. Ensure the size/length of the array is equal to the length of your name plus the null character. Use the strlen function to get the lengths of each name and store them in separate variables. Calculate the total length of your name by adding the lengths of the first name and last name and store it in another…arrow_forwardWrite the statement that declares and instantiates a two dimensional array with 12 rows and 5 columns of type int using the identifier fiveYearPlan.arrow_forwardIn this assignment, you will decide how to keep the inventory in the text file. Then your program must read the inventory from the file into the array. Each product must have a record in the file with the name, regular price, and type. There are several options for storing records in the file. For example, • each value takes one line in the file (i.e., three lines for one product). Then you must take care of correct handling of the ends of the lines; • all values are in one line that can be read as a string. Then you must handle the parsing of the string; • all values are in one line separated by a delimiter. Then you must handle a line with delimiters. Assume that the inventory does not have more than 100 products. But the actual number is known only after the reading of the file. Once you can read data from the file into the array, you must add a new property to the product class – a static variable that holds the number of products in the inventory. Its value must grow as reading…arrow_forward
- Student students[3]; for(int i=0;i<3;i++) fillStruct(&students[i], records[i]); for (int i = 0; i < 3; i++) { printf("Student Name: %s, ",students[i].name); printf("Student ID: %s, ",students[i].id); printf("DOB: %s, ",students[i].ddmmyyyy); printf("City of DOB: %s\n",students[i].cityBirth); } %3D } Task3.1: the program above calls the function fillstruct and provides as arguments one record entry of a student and a pointer of a struct. The function must fill the struct with information of the record. However, for the date entry, the date is provided in a format that needs to be changed: instead of YYYY-MM-DD the date should be filled in the struct as DD- MM-ҮҮҮҮ. Define the function that does the above task void fillStruct(struct studentStruct *std, char currentStd[4][5®]);arrow_forwardStep 1: Read your files! You should now have 3 files. Read each of these files, in the order listed below. staticarray.h -- contains the class definition for StaticArray, which makes arrays behave a little more like Python lists O In particular, pay attention to the private variables. Note that the array has been defined with a MAX capacity but that is not the same as having MAX elements. Which variable indicates the actual number of elements in the array? staticarray.cpp -- contains function definitions for StaticArray. Right now, that's just the print() member function. 0 Pay attention to the print() function. How many elements is it printing? main.cpp -- client code to test your staticarray class. Note that the multi-line comment format (/* ... */) has been used to comment out everything in main below the first print statement. As you proceed through the lab, you will need to move the starting comment (/*) to a different location. Other than that, no changes ever need to be made to…arrow_forwardThe program should allow the user to enter the age of the child and the number of days per week the child will be at the day care center. The program should output the appropriate weekly rate. The file provided for this lab contains all of the necessary variable declarations, except the two-dimensional array. You need to write the input statements and the code that initializes the two-dimensional array, determines the weekly rate, and prints the weekly rate. Comments in the code tell you where to write your statements. 1. Open the source code file named DayCare.cpp using Notepad or the text editor of your choice. 2. Declare and initialize the two-dimensional array. 3. Write the C++ statements that retrieve the age of the child and the number of days the child will be at the day care center. 4. Determine and print the weekly rate. 5. Save this source code file in a directory of your choice, and then make that directory your working directory. 6. Compile the source code…arrow_forward
