Dynamic Memory Allocation In C++

 Dynamic Memory Allocation In C++

What is dynamic memory allocation?

Dynamic memory allocation in C/C++ refers to performing memory allocation manually by programmer. Dynamically allocated memory is allocated on Heap and non-static and local variables get memory allocated on Stack

Why we use Dynamic Memory Allocation?

Dynamic Memory Allocation is to allocate memory of variable size which is not possible with compiler allocated memory except variable length arrays. The most important use of dynamic memory allocation is the flexibility as the programmers are free to allocate and deallocate memory whenever we need and when we don't.

#include<iostream>
using namespace std;
class simple
{
 int *p; // defining a pointer as we are going to work with dma
 public:
 simple(int x) // Parameterized constructor
 {
 // allocating dynamic memory
 cout<<"I am paramertized constructor"<<endl;
 p=new int ; //new int will return the dynamically created adress
 *p = x; // x value is stored in *p i.e. value stored in p.
 }
 
 simple(simple &obj) // USER DEFINED COPY CONSTRUCTOR
 {
 cout<<"I am copy constructor"<<endl;
 // now copying the values of object 1 variable to object 2 variable.
 p=new int()
 *p=*obj.p
 
 }
 void disp() // for diplaying values
 {
 cout<<"The value is : "<<*p<<endl;
 cout<<"I will give the adress of varaible : "<<p<<endl;
 // we will se that for each value address is different
 }
};
int main()
{
 simple s1(10);
 simple s2(s1);
 s1.disp();
 s2.disp();
 return 0;

Array Of Objects In C++ | Array Of Objects Explained With Real Life Example

 Array Of Objects In C++ What is an array of objects? As you know about the array that it is a set of anything like if there is an array of characters then there will be a set of characters. So the same concepts will be applied to objects - A array of objects will be a set of objects. To understand array of objects more clearly suppose you have a form for a job application and you want to send same job application to 100 people. Then rather then creating 100 job application from scratch you can photocopy the same job application form 100 times.Right? So here how you can create array of object in c++ -  #include   < iostream > using   namespace   std ; class   School {      public :        int   std_id ;      int   std_class ;      float   percentage ;      void   add_details ()      {                   cout << " Enter The Student ID:  " << endl ;          cin >> std_id ;          cout << " Enter The Class Of The Student:  " << end

Pointers In C++ | Pointer Explained With Real Life Examples | Pointers In OOPs C++

Pointers In C++ What is pointer in c++ ? If you searched about pointers in c++ on google probably you saw that  In C++, a  pointer  refers to a variable that holds the address of another..... BlahBlahBlah..... But you won't able to understand too much about pointers. So don't worry I will explain this concept very easily by a real life example.   So before understanding about pointers first you have to understand why we need pointers? As you know basically when you create variable then it will occupy some space in your pc. And when you create a another variable with same value or modify that variable with some other value then it will occupy more space in the pc. For example -  #include   < iostream > using   namespace   std ; int   main () {      int   var   =   12 ;  //Suppose This will occupy some space which ID is AB12      int   var1   =   12 ;  //Now This will also occupy some space which ID will be BB12 (ALWAYS DIFFERENT)           var   =   45 ; //This will also

Destructor In C++ | Destructor Explained With Real Life Examples

 Destructor In C++ What is a Destructor ? As you previously understood about Constructor . You know how constructor works so destructor is opposite of that -  What are opposite in destroctor -  - Destructor call the end of a class always - Destructor takes no argument - Destructor won't return anything - To Modify a constructor you should use ~className Other than that Destructor is same as constructor. #include   < iostream > using   namespace   std ; class   myClass {           public :      ~   myClass ()      {          cout << " I AM A DESRUCTOR " << endl ;      }      void   get ()      {          cout << " I am a simple method " << endl ;      }      }; int   main () {      myClass   m1 ;      m1 . get ();      return   0 ; } Output -  I am a simple method I AM A DESRUCTOR Here you can see we define destructor at starting in class but the destructor executed at last always.
