+# --- Loops --------------------------------------------------------------- #
+#
+# Looping constructs are available in the form of while and do-while 
+# statements. The while statement checks the condition before each
+# iteration:
+
+i = 0;
+while i < 10:
+	i = i + 1;
+
+# This loop runs for 10 times. As for the if-else statement, a single
+# statement is expected as the body of the while statement. You can
+# provide it a compound statement tho.
+
+i = 0;
+while i < 10:
+	{
+		print('While iteration no. ', i, '\n');
+		i = i + 1;
+	}
+
+# The do-while statement checks the condition at the end of each
+# iteration. This means that at least one iteration is performed!
+
+i = 0;
+do
+	{
+		print('Do-while iteration no. ', i, '\n');
+		i = i + 1;
+	}
+while i < 10;
