- To effectively utilize a shared virtual function across multiple forms and structures, what is the appropriate method for a program to invoke it when employing base class pointers or references?For many data types and structures, how should software use pointers or references to a base class to invoke the same virtual function several times?Your task for this lab is to create an easy-to-use Matrix class in C++ that makes use of dynamic memory allocation and includes basic matrix operations both in the form of regular functions and via operator overloading as shown below. **********MATRIX - 1********** Enter the rows of the matrix : 3 Enter the cols of the matrix : 3 Enter 1 th row elements : 123 Enter 2 th row elements : 456 Enter 3 th row elements :789 **********MATRIX - 2********** Enter the rows of the matrix : 3 Enter the cols of the matrix : 3 Enter 1 th row elements : 345 Enter 2 th row elements :678 Enter 3 th row elements :123 **********ADDITION********** 468 10 12 14 8 10 12 *Subtraction* ******* -2 -2 -2 -2 -2 -2 666 **********Mutiplication** 18 24 30 48 63 78 78 102 126 **********EQUALITY********** Are both matricex equal ?

- Pointers A pointer is basically a reference to an object or a function. In fact, it is a variable that holds memory address. This address is the location of some other variable or object in memory. For example, if one variable contains the address of another variable, first one is said to point to the second one. Pointers may have many uses, such as to make functions implement “call-by-reference” methodology and to construct dynamic arrays or structures at run-time. a) Write a complete C program that demonstrates the usage of call-by-reference technique needed for swapping. Develop a call-by-value version to see that changes done to the parameters inside the function are lost. b) Write a complete C program that implements below given user-defined function prototypes for arrays-of-integers. void input_1d_array( int*, int ); void output_1d_array( int*, int ); int sum_1d_array( int*, int ); float average_1d_array( int*, int ); Test each function separately! c) [if time allows]…1. Please explain in detail Scott Meyers’s point: Use weak_ptr for shared_ptr like pointers that can dangle. 2. How are Smart Pointer functions move(), reset(), and release() different from each other? Please also explain in detail which function is most dangerous and why? 3. Please explain in detail how to manually destroy an existing Smart Pointer control block.java language A system needs to have a Validation class that can validate the input for instance variables ofthe different classes given in Table 1. It should validate the values for the data members from different classesusing Regular Expressions, such that a name can only contain alphabets from A to Z or a to z and the firstletter is always a capital letter. The address should start with a number followed by one or two words (forexample 16 Khyber or 16 Khyber Ave). The phone number should have a format like 0-000-0000000 where the first digit is always a 0. The e-mail address should contain exactly one ‘@’ character and at least one ‘.’character. A car’s registration number can only contain a maximum of 3 English alphabets followed by notmore than 4 digits. All the classes should be able to validate their data without creating the objects
- In C programming: Write a function printCourse() which receives a course pointer and prints all its fields, 1 field per line, using the following conditions:• The labels (“Department”, “Course Number”, …) are left aligned• The values are right aligned• Course numbers must have leading zeroesPlease solve in C++ LAB TASK □Let suppose you are working as a Software Developer at UOL, and you are required to develop a Employee Registration System to maintain the records of the Employee. You will have create four functions AddEmployee() → EmployeelD and EmployeeName SearchEmployee()→ Search By EmployeelD Delete Employee() → Delete by EmployeelD Print() → Print the record of all Employees. Use the appropriate Data Structure to implement the following functionalities. 0How should a software utilize pointers or references from the base class to invoke the same virtual function so that it may be used in different data types?
- Define global pointer.T or F -Functions are considered to be objects in JavaScript because they contain three critical attributes: data, methods that act on the data, parameters for passing the data also known as awareness. -A recursive function is a function that calls itself and eventually returns default value to break out of the recursion. -A function that is used to create a new object is called an anonymous function. -Attributes define additional characteristics or properties of the element which is the same as for the start tag. -Javascript is similar to the Java programming languageHow can code use pointers or references from the base class to execute the same virtual function so that it may be utilised across multiple data types?
