Why does an extremely large value cause this code to repeat infinitely?

I hope this helps . The failbit of cin will be set if the input number is too large to be stored in an int, then following cin >> n will always fail. You can use cin.clear() to clear the failbit before cin >> n:
code :
int n;  

do
{
    cin.clear();  // <-----
    cout << "What height should the pyramid be? ";
    cin >> n;
} while (n <= 1 || n > 23);

around this issue See example animMotion01 in the w3 SVG spec for a fairly reduced example illustrating SVG animation (including use of repeatCount="indefinite"):
code :
<svg width="5cm" height="3cm"  viewBox="0 0 500 300"
     xmlns="http://www.w3.org/2000/svg" version="1.1"
     xmlns:xlink="http://www.w3.org/1999/xlink" >
  
  <desc>Example animMotion01 - demonstrate motion animation computations</desc>
  
  <rect x="1" y="1" width="498" height="298"
        fill="none" stroke="blue" stroke-width="2" />
  
  <!-- Draw the outline of the motion path in blue, along
          with three small circles at the start, middle and end. -->
  <path id="path1" d="M100,250 C 100,50 400,50 400,250"
        fill="none" stroke="blue" stroke-width="7.06"  />
  <circle cx="100" cy="250" r="17.64" fill="blue"  />
  <circle cx="250" cy="100" r="17.64" fill="blue"  />
  <circle cx="400" cy="250" r="17.64" fill="blue"  />
  
  <!-- Here is a triangle which will be moved about the motion path.
       It is defined with an upright orientation with the base of
       the triangle centered horizontally just above the origin. -->
  <path d="M-25,-12.5 L25,-12.5 L 0,-87.5 z"
        fill="yellow" stroke="red" stroke-width="7.06"  >
    
    <!-- Define the motion path animation -->
    <animateMotion dur="6s" repeatCount="indefinite" rotate="auto" >

Any of those help I could be wrong, but when I run your code I get small values. Could it be that you're seeing things like -3.53107108e-310 and confusing them for large numbers? That's:

The simplest possible infinitely repeat

The simplest possible infinitely repeat

I hope this helps you . I need the simplest possible Timer to repeat my code infinitely every 5 seconds. No external classes or whatnot.. , Use while(true) with Thread.Sleep
code :
    using System.Threading;

    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Now the following code will be repeated over and over");

            while(true)
            {
                //////////////// FOLLOWING CODE /////////////////
                /* the repeated code */
                //////////////// END OF FOLLOWING CODE /////////////////
              Thread.Sleep(5000);
            }   
        }
    }
Repeat SVG horizontally infinitely

I wish this help you The idea here is that you wish to 'mimic' the background into repeating. I'm not sure this is the best solution, it's just one that I have used in the past and am very fond of.
First, we'll duplicate the background svg with the same properties and call it #back instead of #front.
code :
keyframes frontScroll {
    from {transform: translateX(0);}
    to {transform: translateX(100%);}
}
keyframes backScroll {
    from {transform: translateX(-100%);}
    to {transform: translateX(0%);}
}
body {
  margin : 0;
  overflow : hidden;
}
#front {
  position : absolute;
  left :0;
  right:0;
  bottom:0;
  z-index : 9;
  -webkit-animation: frontScroll 2.5s linear infinite;
 animation: frontScroll 2.5s linear infinite;
}

#back {
  position: absolute;
  bottom: 0;
  right: 0;
  left: 0;
  z-index: 9
  -webkit-animation: backScroll 2.5s linear infinite;
  animation: backScroll 2.5s linear infinite;
}

keyframes frontScroll {
from {transform: translateX(0);}
to {transform: translateX(100%);}
}

@-webkit-keyframes frontScroll {
from {transform: translateX(0);}
to {transform: translateX(100%);}
}

keyframes backScroll {
from {transform: translateX(-100%);}
to {transform: translateX(0%);}
}

@-webkit-keyframes backScroll {
from {transform: translateX(-100%);}
to {transform: translateX(0%);}
}

I think the issue was by ths following , A problem I had in the past that seems related to your issue: If you include whatever directive that access a template through "templateUrl" but for some reasons, angular can't resolve the templateUrl of this directive, by default it will return the template for index.html which will contain again your directive and because the templateUrl for the directive is not found, it default again to index.html
and so on....
