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]…

Pointers (and/or reference) types are necessary in modern programming languages because they aid readability and reliabilty they provide the means to access and manipulate dynamic storage they are easy to use and easy to get right otherwise everyone would be able to program

Choose the correct alternatives for the following:   iv) Representation of data structure in memory is known as a) Recursion b) Abstract data type c) Storage structured) File structure   v) An ADT is defined to be a mathematical model of a user-defined type along with the collection of all operations on that model a) Cardinality b) Assignment c) Primitive         d) Structured

In C++ Declare a Character Pointer and allocate a dynamic array of 22 characters.

Match the following memory/pointer concepts and code structures: Leading asterisk, like *p pointer reference Trailing asterisk, like int* pointer variable data type Leading ampersand, like &a the thing pointed to by a poin v Trailing ampersand, like int& the memory location of a varia v Trailing star-ampersand, like int*& non-pointer reference

It is a type used to represent a heterogeneous collection of data. array O function struct pointer Check It! Structure is a user-defined data type in C which allows you to combine different data types to store a particular type of record. O True False Check It!

Programming Language: C++  Make a program wherein you have to create an Abstract Data Type, which will store 2 integer number. After that, make operations which will set the value of the two numbers, add, subtract, multiply and divide. After creating the abstract data type, use it in the main class. Ask the user for the value of two integers. Ask the user what operation to use, then call the necessary operation based on the user's input. Then display the answer with the correct label. Do not copy paste codes from other sites.

Write a C/C++ function that receives, as arguments, a pointer to a double array, as well as the number of elements in the array (int). The function must use pointer operations (no block notation such as arr[i]) and must display each element in the array.

Abstract data types are not specifically specified types of data.

Subject : Data structure and algorithms Goal of the work : Consolidating knowledge on the theoretical foundations of abstract data structures, mastering the skills of calculating the declared amount of memory for structures using C++ syntax. Task : Given a data structure with three fields: an array of integers, a matrix of real numbers, and a string of characters. Calculate the total memory size (in bits, bytes, kilobytes, and megabytes) for record A, table B, and dynamic array variables C. *note: The data types are respectively equal to the memory size "short-2 byte", "int-4", "long-8", "float-4", "double-8", "long double -12", " char-1".

*Java code* Implement a data structure called RunningTotal supporting the following API: a) RunningTotal() - creates an empty running-total data structure b) void add(int value) - adds the given value to the data structure c) void remove() - removes the least-recently added value d) int sum() - returns the sum of values in the data structure e) double average() - returns the average of values in the data structure   Here's a Example: RunningTotal rt = new RunningTotal ();rt . add (1); // 1 ( adds 1 )rt . add (2); // 1 2 ( adds 2 )rt . add (3); // 1 2 3 ( adds 3 )rt . sum (); // 1 2 3 ( returns 6 )rt . add (4); // 1 2 3 4 ( adds 4 )rt . remove (); // 2 3 4 ( removes 1 )rt . sum (); // 2 3 4 ( returns 9 )rt . average (); // 2 3 4 ( returns 3.0 )

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 language

Function Implementation with Data Abstraction in C Programming 1. Create a new file and SAVE as MATHV1.H Define and Implement the following functions: int sum(int x, int y); - returns the computed sum of two numbers x and y int diff(int x, int y); - returns the computed difference of two numbers x and y. Make sure that the larger number is deducted by the smaller number to avoid a negative answer long int prod(int x, int y); - returns the computed product of two number x and y float quot(int x, int y); - returns the computed quotient of two numbers x and y. Make sure that the larger number is always the numerator and divided by the smaller number to avoid division by zero error. int mod(int x, int y); - returns the computed remainder of two numbers x and y using the modulo operator %2.

Why is ‘this’ Pointer is widely used than object pointer?

The design of pointers has been associated with certain issues. Most programming languages restrict pointers to referencing only one type of variable.

Upload answer sheets Write a C program to find the number of occurrences of characters in the first string which is present in the second string using pointers.

What are any similarities that exist between a reference and a pointer?

In C programming: Write a main() function using the following requirements:• Define a SIZE constant (the value is irrelevant, but for testing, you may want to keep it small enough – no bigger than 5)• Create an array of course pointers using SIZE• Dynamically allocate each element of the array• Call inputAllCourses()• Call printAllCourses().

What are some ways in which a reference and a pointer are alike?

C LANGUAGE IS THE NEEDED COMPUTER LANGUAGE. COUT something like that.

What are the advantages of an enumeration type over a set of named constants? What are the advantages of a subrange type over its base type? In what instances may a string be better than a character array?
