Answer:

a.True.

Explanation:

To delete a node from linked list it is best to do it by using two pointers suppose say prev and curr. Iterating over the linked list while curr is not NULL and updating prev also.On finding the node to be deleted we will set the prev so that it points to the next of curr and after removing the link we will free curr from memory.

line of code for deleting a node in c++:-

prev->next=curr->next;

delete curr;  or  free(curr);

Explanation:

#include <iostream>

#include <cctype>

#include <string.h>

#include <cstring>

#include <sstream>

using namespace std;

struct Car {

public:    

char reportingMark[5];    

int carNumber;

string kind;

bool loaded;

string destination;

};

void input(Car *);

void output(Car *);

int main() {

Car *T = new Car;    

input(T);

output(T);    

delete T;    

return 0;

}

void input(Car *T)

{

string str, s;

cout << " Enter the reporting mark as a 5 or less character uppercase string: ";

cin >> str;

for (int i = 0; i < str.length(); i++)

T->reportingMark[i] = toupper(str[i]);

cout << " Enter the car number: ";

cin >> T->carNumber;

cout << " Enter the kind: ";

cin >> T->kind;

cout << " Enter the loaded status as true or false: ";

cin >> s;    

istringstream(s) >> boolalpha >> T->loaded;    

if (T->loaded == true) {

cout << " Enter the destination: ";

cin.ignore();

getline(cin, T->destination);

}

else

T->destination = "NONE";    

}

void output(Car *T)

{

cout << " Reporting Mark: " << T->reportingMark;

cout << " Car Number: " << T->carNumber;    

cout << " Kind: " << T->kind;

cout << " Loaded Status: " << boolalpha << T->loaded;

cout << " Destination: " << T->destination << " ";

Samantha is in the beginning stages of OOP program development. What are the five steps she must follow for creating an OOP prog
lora16 [44]

Answer:

1. Classes and objects

2. Inheritance

3. Polymorphism

4. Data hiding/ encapsulation

5. Interfaces.

Explanation:

Classes and objects depict the major component of the OOP (object oriented programming). It explains the object like a ball in a soccer game development.

The inheritance is like the subclass of the object. Data hiding is a stage in oop where the codes or data are hidden from another users.

In the polymorphism stage, the object is given the ability to change to a sub-object, while in the interface stage a function or method signature is defined without implementing it.

1. Write a program that declares an array named alpha with 50 components of the type double. Initialize the array so that the fi
Aleksandr [31]

Answer:

Explanation:

1. Write a program that declares an array named alpha with 50 components of the type double. Initialize the array so that the first 25 components are equal to the square of the counter (or index) variable and the last 25 components are equal to three times the index variable.  

  double alpha[50];

   for (int i=0;i<25;i++)

   {

       alpha[i]=i*i;

       alpha[i+25]=(i+25)*3;

  }

2. Output the array so that exactly ten elements per line are printed.  

   for (int i=0;i<50;i++)

   {

       cout<<i+1<<". "<<alpha[i]<<" ";

       if (((i+1)%10)==0)

       {

           cout<<endl;

       }

   }

3. Run your program again, but this time change the code so that the array is filled with random numbers between 1 and 100.  

   double alpha[50];

   for (int i=0;i<50;i++)

   {

       alpha[i]=rand()%101;

   }

   for (int i=0;i<50;i++)

   {

       cout<<i+1<<". "<<alpha[i]<<" ";

       if (((i+1)%10)==0)

       {

           cout<<endl;

       }

   }

4. Write the code that computes and prints the average of elements of the array.  

   double alpha[50],temp=0;

   for (int i=0;i<50;i++)

   {

       alpha[i]=rand()%101;

       temp+=alpha[i];

   }

   cout<<"Average :"<<(temp/50);

5. Write the code that that prints out how many of the elements are EXACTLY equal to 100.

   double alpha[50],temp=0;

   for (int i=0;i<50;i++)

   {

       alpha[i]=rand()%101;

       if(alpha[i]==100)

       {

           temp++;

       }

   }

   cout<<"Elements Exacctly 100 :"<<temp;

Please note:  If you put  each of above code to the place below comment  it will run perfectly after compiling

#include <iostream>

using namespace std;

int main()

{

   // If you put  each of above code here it will run perfectly after compiling

   return 0;

}
