Password Security in C

Hi guys in this article I would like to share with you a sample program that I wrote that will ask the user to give a password and check if the given password is valid or not. What is good about this program it does not display the password while the user is type it instead it display the asterisk symbol in order to hide the real password to the user. The code is very simple and short I hope you will find my work useful.  I am using Dev C++ as my C++ compiler in this program. Thank you.

Swapping of Two Numbers in C++

Here is a sample program that I wrote a long time ago while I'm working as a college professor teaching C++ programming subjects. This type of program will ask the user to give two numbers and then it will swap or interchange the arrangement of the two numbers given by our user. I am using CodeBlocks as my C++ editor and Dev C++ as my C++ compiler all of them are free to download over the Internet. Thank you.
