Problem with WHILE loop

[sr2cute702]

Hello all,

I have an exercise im working on and its not working due to the while loops i think.

this is what it gives me.

values for x

75 678 13 4

Starting at 75 it takes 12 steps to reach 1
The largest number in the series is 340 at position 4
Starting at 678 it takes 45 steps to reach 1
The largest number in the series is 4372 at position 30
Starting at 13 it takes 45 steps to reach 1
The largest number in the series is 4372 at position 30
Starting at 4 it takes 45 steps to reach 1
The largest number in the series is 4372 at position 30

this is what the correct output should be

Starting at 75 it takes 14 steps to reach 1
The largest number in the series is 340 at position 4
Starting at 678 it takes 51 steps to reach 1
The largest number in the series is 4372 at position 19
Starting at 13 it takes 9 steps to reach 1
The largest number in the series is 40 at position 2
Starting at 4 it takes 2 steps to reach 1
The largest number in the series is 4 at position 1

#include<iostream>
using namespace std;


int main()
{
  int x;
  int y;
  int a=1;
  int s=0;
  int j = 1;
  int i = 1;

  cin>>x;


  while (cin) // loop that will run formulas untill there is no more data
    {

  cout<< "Starting at "<<x; // this out puts the firts x values 

  while(a<= x)  // formula that runs and build the sequence untill it reaches 1
    {

 	a++;
 	y=x%2;
 	if(y==0)
 	{
 	x=x/2;
 	}
 	else
 	{
 	x=3*(x+1);
 	x=x-2;
 	}
      while (j<x) // loop that looks thru the sequence built by the formula above and finds the large number
        {

          j++;



          if (s<x) // finding the largest number in the sequence 
            {
              s=x;

            }
          while (i < a ) // the index number of the largest number
            {

              i++;
            }
            



        }

        }
    




  cout<<" it takes "<<a<<" steps to reach 1"<<endl;
  cout<< "The largest number in the series is "<<s<<" at position "<<i <<endl;



  cin>>x;
    }
    
  return 0;

Enter a number: 678

 88 44 22 11 34 17 52 26 13 40 20 10 5 16 8 4 2 1 
Starting at 678 it takes 52 steps to reach 1
The largest number in the series is 4372 at position 19
