Explanation of Solution
Structure:
In C++, the structure is a user-defined data type, which contains different type of elements with different lengths.
- The size of the structure is calculated by the total number of elements which is declared in a structure.
Structure pointer operator (->):
The structure pointer operator (->) can be used with a structure pointer variable to access the members of a structure; this operator does automatically dereferences its left structure pointer.
- It can be referred as an alternative for indirection operator (*).
Example:
The following example is used to declare a function named “getValues()” and then to access the structure members using structure pointer operator (->):
//Include required header files
#include <iostream>
using namespace std;
//Declare a structure
struct Values
{
//Declare the member variables
string name;
int age;
//D...

- What effect does the new operator have when constructing instances of structures?arrow_forwardWhy should you utilise the new operator when creating structure instances?arrow_forwardAssume the following structure declaration exists in c++. struct Rectangle{int length;int width;}; Now Assume rptr is a pointer to a Rectangle structure. Which of the expressions, A, B, or C, is equivalent to the following expression: rptr->widtha) *rptr.widthb) (*rptr).widthc) rptr.(*width) ( Drop screenshot of output as well )arrow_forward
- C code blocks nly write the missing structure definition which is required to complete the program below. The program determines the distance between two 3D points. The structure should have three members: X, Y and Z of type float. // Your answer starts here// Your answer ends herefloat distance(point n1, point n2);int main(){point n1, n2;float temp;scanf("%f %f %f", &n1.X, &n1.Y, &n1.Z);scanf("%f %f %f", &n2.X, &n2.Y, &n1.Z);temp = distance(n1, n2);printf("Distance = %.1f", temp);return 0;}float distance(point n1, point n2){float temp;temp = sqrt(pow(n1.X-n2.X,2)+pow(n1.Y-n2.Y,2)+pow(n1.Z-n2.Z,2)); return temp;} For example: Input Result 2.3 4.5 2.5 3.4 5 9.8 Distance = 9.9arrow_forwardT/F The << operator is overloaded to input data items of fundamental types, strings and pointer valuesarrow_forwardEffects on Size and PaddingA flexible array member is treated as having no size when calculating the size of a structure, though paddingbetween that member and the previous member of the structure may still exist:/* Prints "8,8" on my machine, so there is no padding. */printf("%zu,%zu\n", sizeof(size_t), sizeof(struct ex1));/* Also prints "8,8" on my machine, so there is no padding in the ex2 structure itself. */printf("%zu,%zu\n", sizeof(struct ex2_header), sizeof(struct ex2));/* Prints "5,8" on my machine, so there are 3 bytes of padding. */printf("%zu,%zu\n", sizeof(int) + sizeof(char), sizeof(struct ex3));The flexible array member is considered to have an incomplete array type, so its size cannot be calculated usingsizeof.arrow_forward
- 3. Assume you have the following structure definition: struct parts { string name; int num; float price; int qInStock; }; a. Write a program that declares an array of the parts structure, size 10, name of your choice, and includes the following: Write a void function to request user input into each of the component members of the parts structure array. Be sure to include proper user prompts. Assume the entire structure array is filled. Write the prototype and the function definition. Call the function from main.Write a void function to output the information in the parts structure array. Write the prototype and the function definition. Call the function from main.arrow_forwardWrite program in C. Create a structure called Studentsthat holds information likeRegistration code, name of student and date of admission. Write a program tocreate an array of structures and enter some data into it (15 records at least). Then ask the user to enter current date. Display the names of those Students who are in the school greater than or equal to 5 years.arrow_forwardWhat effect does the new operator have when creating an instance of a structure?arrow_forward
- A data structure in which all elements have the same type is called an ______arrow_forwardDefine a structure named Gamer which will have the following elements: Number_of_ favorite_games (int), List_of_favorite_games (2D string). Now declare a structure array of Gamer for 5 gamers and take inputs for them. Now generate a rank list of the games. (Hint: The game which appeared most in the favorite games list will be the top game. In case of tie, print the game which comes alphabetically before).arrow_forwardSUBJECT: PROGRAMMING FUNDAMENTELS LAB IT provides best solutions for manual work that makes life easier .Suppose a university wants to manage its data in the form of software. Being a programmer you have been asked to create the following structures in C. 1. Student: a. Name b. RegId c. Enrolled courses (Labs + Theory) d. Department e. Semester2. Faculty: a. Name b. Department c. Designation d.
