 C++ (also crippled C) is an [object-obsessed](oop.md) [joke](jokes.md) language based on [C](c.md) to which it adds only [capitalist](capitalist_software.md) features and [bloat](bloat.md), most notably [object obsession](oop.md). Most good programmers such as [Richard Stallman](rms.md) and [Linus Torvalds](linus_torvalds.md) agree that C++ is hilariously messy and also tragic in that it actually succeeded to become mainstream. The language creator [Bjarne Stroustrup](stroustrup.md) himself infamously admitted the language sucks but laughs at its critics because it became successful anyway -- indeed, in a retarded society only [shit](shit.md) can succeed. As someone once said, "C++ is not an increment, it is excrement". C++ specification has **over 2000 pages** :D
 
-C++ source code files have the extensions `.cpp` or `.cc` (for "crippled C").

+Here is our standardized **[divisor tree](divisor_tree.md)** program in C++:
+
+```
+#include <iostream> // include standard I/O library
+using namespace std;
+
+// recursive function, prints divisor tree of x
+void printDivisorTree(unsigned int x)
+{
+  int a = -1, b = -1;
+ 
+  for (unsigned int i = 2; i <= x / 2; ++i) // find two closest divisors
+    if (x % i == 0)
+    {
+      a = i;
+      b = x / i;
+
+      if (b <= a)
+        break;
+    }
+
+  cout << '(';
+  
+  if (a > 1)
+  {
+    printDivisorTree(a);
+    cout << ' ' << x << ' ';
+    printDivisorTree(b);
+  }
+  else
+    cout << x;
+    
+  cout << ')';
+}
+
+int main()
+{
+  while (1) // main loop, read numbers from the user
+  {
+    unsigned int number;
+    cout << "enter a number: " << flush;
+    cin >> number;
+    
+    if (!cin.fail() && number < 1000)
+    {
+      printDivisorTree(number);
+      cout << endl;
+    }
+    else
+      break;
+  }
+
+  return 0;
