Infinite While loop in C++ programming language

Infinite While loop in C++ programming language

A while loop that never stops is said to be the infinite while loop, when we give the condition in such a way so that it never returns false, then the loops becomes infinite and repeats itself indefinitely.

An example of infinite while loop:

This loop would never end as I'm decrementing the value of i which is 1 so the condition i<=6 would never return false.

#include <iostream>
using namespace std;
int main(){
   int i=1; while(i<=6) {
      cout<<"Value of variable i is: "<<i<<endl; i--;
   }
}

Example: Displaying the elements of array using while loop

#include <iostream>
using namespace std;
int main(){
   int arr[]={23,88,13,99, -26};
   /* The array index starts with 0, the first element of array has 0 index and represented as arr[0]     */
   int i=0;
   while(i<5){
      cout<<arr[i]<<endl;
      i++;
   }
}
