Arrow Operator

What's Arrow Operator ??

Actually, arrow operator is used to tend down from any higher value to the lower value using the while loop in the programs.

* Used for tending down any higher value to lower value*

---------------------------------------------------------------------------------------------------------

Lets say, we have the value of 'i=10'. and we want to move towards '0' by printing all these values of the variable 'i'. 

Then, we can simply apply the 'arrow operator(-->)' in the while loop without using any decremental statement like 'i--' in the while loop for the variable 'i'.

So the Simple code for this example would be :

#include<iostream.h>

#include<conio.h>

#include<stdlib.h>

void main()

{    clrscr();

  int i=10;

  cout<<"Tending Down Value of Variable i is \n";

  while(i-->)                 // Arrow Operator ( --> )

{

  cout<<i<<"\n";

}

  system("pause");

}

So, the output of the code will be :

Tending Down Value of Variable 'i' is 

10

 9

 8

 7

 6

 5

 4

 3 

 2

 1

 0

*It reduces the use of decremental statements in the loop* 

--------------------------------------------------------------------------------------------------------

So, By using the 'arrow operator', we can get rid of the decremental statements in the while loop.
Here, this task could also be performed simply using the statements as :

while(i>0)
{
  i--;                  // decremental statement ( i-- )
  cout<<i<<"\n";

}

But , the 'arrow operator' makes this conditional useless.
