- 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. Write a complete C program that implements below given user-defined function prototypes for arrays-of-integers. * void input_ld_array( int*, int ); void output_ld_array( int*, int ); int sum_ld_array( int*, int ); * float average_ld_array( int*, int ); v Test each function separately!The programmer constructs a class to isolate the functionality of an implementation from the kind of data utilized in it.

- 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?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 ? No *MATRIX TRANSPOSE* 147 258 369 Press any key to continue ...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?
- please write with proper explanation. Question half solution is here please write what is main disadvantages of this approach? Half solve questions: Mutual Exclusion: Mutex is an abbreviation for Mutual Exclusion. It is a programme object that prevents multiple users from accessing a shared resource at the same time. When a process accesses a shared variable, it is said to be in the critical section. When no two processes are present in the critical section at the same time, this is referred to as Mutual Exclusion or Mutex. while (true) { semaphore sem = S; while (S <= 0) do no operation { S = S-1; wait (S); } /*critical section*/ while (S > 0) { S = S+1; signal (S); } /*remainder section*/ }Please 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. 0In 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 zeroes
