Many people still don’t fully understand how to use pointers. This example is from C++ For Dummies 5th Ed. I hope this helps.

A pointer variable is a variable that contains an address, usually the address of another variable. Returning to my hotel analogy for a moment, I might tell my son that I will be in room 0×100 on my trip. My son is a pointer variable of sorts. Anyone can ask him at any time, “Where’s your father staying?” and he’ll spill his guts without hesitation.

mySon = &DadsRoom; // tell mySon the address of Dad’s Room
room = *mySon; // “Dad’s room number is”

Well I made a script again that converts string to MD5. It’s simple. I’m just bored and want to post something simple that is useful to others, so I made this converter. hahaha! Check it out.

What is MD5? MD5 (Message-Digest algorithm 5) is a widely used, partially insecure cryptographic hash function with a 128-bit hash value. As an Internet standard (RFC 1321), MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files. An MD5 hash is typically expressed as a 32 digit hexadecimal number.

I made this converter for everyone. Check it out.
