If you want to multiply any number by 100
Try this :-

 Help with Code Tags 
 CPP Syntax (Toggle Plain Text) 
   int result = 0;
   int x;
   cout << "Enter Any Number " << endl;
  cin>>x;
  for ( int i = 1 ; i <= (100 /2) ; i++)
 {
		result += x << 1;
 
}
   int result = 0;
   int x;
   cout << "Enter Any Number " << endl;
  cin>>x;
  for ( int i = 1 ; i <= (100 /2) ; i++)
 {
		result += x << 1;
		
}

if u want to multiply by n just replace 100 with n.
But BEWARE this works when n is even only.
Find by yourself how to overcome this when n is odd.

funny you didnt qualify your "solution" with the "hey i'm a beginner" disclaimer, why are you falling back on it now?

whatever, if you're a beginner, then don't use this site to give wrong advice to other beginners. a good intention is no substitute for correct code.
