Btw - There is no need to introduce new scopes for your
'if' statements, and you will probably get into trouble
early on in your learning by introducing these.

I would recommend that you play around with 'else if'
statements as well as 'if', which can help you reduce
having to include multiple if statements to evaluate
user input.

For example:

  if( x < 20 )
      cout<< "Thank you";
  else if( x > 20 )
      cout<<"Great job ";
  else
      cout << "You entered 20 ";

Additionally, the identifier 'x' is ok for toy programs
like this, but you should get into the habit of using
meaningful identifier names to make your code easier to
understand - initialising your variables is also recommended
in most cases.

Cheers.
