Array Reverse Program in java

class Array_Reverse{

          public static void main (String[] args){
             int a[]={4,6,3,1,5};
             int t;

             for(int i=0,j=a.length-1;i<j;i++,j--){
                                   t = a[i];
				  a[i] = a[j];

Access array elements using foreach.

  class Array_Example {
          public static void main (String[] args){
                  int a[]={4,6,3,7,9};
                  for(int i : a ){
                              System.out.print(i + " ");
                  }
             
          }
}

Create array in java

class Array_Example {
          public static void main (String[] args){
                  int a[]={4,6,3};
                  for(int i=0; i<a.length;i++){
                              System.out.print(a[i]+" ");
                  }
             
          }
}

Multilevel Inheritance in C++

A class is derive from a class which is derive from another class is known as multilevel inheritance or we can say derived class work as a base class for another derived class called multilevel inheritance.

Single level Inheritance

When a class is derived from single base class and derived class can’t work as base class for another class called single level inheritance.
Example:

class A{

    public:

       void show(){

                  cout<<"show\n";

       }

};
