    int a, b, c;  
  
    a = 2;  
    b = 3;  
  
    if(a < b) 
        Console.WriteLine("a is less than b"); 
 
    if(a == b) 
        Console.WriteLine("you won't see this");  
 
    Console.WriteLine(); 
 
    c = a - b;
 
    Console.WriteLine("c is",c); 
    if(c >= 0) 
         Console.WriteLine("c is non-negative"); 
    if(c < 0) 
         Console.WriteLine("c is negative"); 
 
    Console.WriteLine(); 
 
    c = b - a;
    Console.WriteLine("c is",c); 
    if(c >= 0) 
        Console.WriteLine("c is non-negative"); 
    if(c < 0) 
        Console.WriteLine("c is negative"); 
  }  
}
a is less than b

c is
c is negative

c is
c is non-negative
