C++ Tutorial- Program- 11- Arrays- One Dimention

Code:

#include <iostream.h>   

#include <iomanip.h>   //we use this header file for set w OR Width 

main()

{

   int arr[ 10 ]; // its an integer type array of size 10

/*initialize elements of (array) i.e start with 0 and n-1 means 0to9         

  for sum using for loop*/

  

   for ( int i = 0; i < 10; i++ )

   {

     arr[ i ] = i + 100; 

   // i.e calculation 100 =0 + 100 to 109= 9+100

   }

   cout << "Array Members" << setw( 12 ) << "Values" << endl;

   // again for loop for output/ display                      

   for ( int j = 0; j < 10; j++ )

   {

      cout << setw( 6 )<< j << setw( 17 ) << arr[ j ] << endl;

C++ Tutorial- Program- 17- Pointers

Code:

//Pointers: A pointer is a variable that contains the address of a variable.

#include<iostream>

using namespace std;

main()

{

 int x=100;   // initialize integer type variable name x

 int *y;     // declare integer type pointer y

    cout<<x;  // print value of integer type variable x

    cout<<"\n";   // new line

  y=&x;        // giving address of variable x to y

 *y=5000;    // without accessing x changing value of x=100 to 5000

 cout<<x;     // after, poiting now, value of x is : 5000

 cout<<"\n";  // new line

 int **z;     // declare integer type pointer to pointer c

 z=&y;        // giving address of y to z

 **z=90;     // now, without disturbing x&y value of x is 90

 cout<<x;    //value of x is 90 

}
