Als erstes möchte ich all meinen Besucherinnen und Besuchern Frohe Weihnachten, Merry Christimas, Joyeux Noël, Jwaye Nwèl, Geseënde Kersfees, メリークリスマス ... (Meri kurisumasu for those of you who happen not to speak, and/or understand, Japanese) wünschen.
That said, the small number of blog posts not consisting of code were posted in german (if you haven't guessed.) Since most of my visitors are from the U.S. (or other english speaking countries) , i decided to switch to 日本語 (Nihongo - Japanese language), so you be totally left in the dark what exactly i write here, or will in my source code comments. (joking of course).
As of now i will keep posting in English, to annoy the world with my ramblings about this and that, and all the other things. ;)
Before publishing this post, i think it is also about time to thank those kind souls who took the time to give my posts +'s, Thank you, 本当にありがとうございます。 (Truly appreciated!) Ok, ok, enough Japanese already!
Have a pleasant evening, all and everyone, and check back for more (truly ugly, badly written (you be my guest and fill in some more good things that can be said about it), C++ Code. ;-)

Programming Challenge 5.16 - Savings Account Balance
/* Savings Account Balance - This program calculates the balance of a savings
account at the end of a period of time. It asks the user for the annual
interest rate, the starting balance, and the number of months that have
passed since the account was established. A loop iterates once for every
month, performing the following:
* The user is asked for the amount deposited into the account during the
month. This amount is added to the balance.
Input Validation: No negative numbers are accepted.
* The user is asked for the amount withdrawn from the account during the
month. This amount is subtracted from the balance.
Input Validation: No negative numbers are accepted.
* Calculating the monthly interest:
The monthly interest rate is the annual interest rate divided by twelve.
The monhtly interest rate is multiplied by the balance, and the result is
added to the balance.
After the last iteration, the program displays the ending balance, the total
amount of deposits, the total amount of withdrawals, and the total interest
earned.
Notice: If, at any point, a negative balance is calculated, a message will
be displayed, indicating that the account has been closed and the loop will
terminate. */
