Make a numerology calculator.
I had to write a simplified one in my C++ course. The simple one wasn't very interesting but a fully featured one might.
Input to the program would be the person's first and last name.
Using a specific algorithm the program generates a special numerology number that has a meaning.
The algorithm basically works like so.....each letter of the alphabet is assigned a number such as:
Each letter of the person's name is then added up using the numbers assigned to the letters. Using that sum each digit of that sum is then added up, and then from that sum each digit is added up, and so on until only one digit remains. That would be the special number.
Then that special number has a predefined meaning.
The exact process and algorithm and meanings of the numbers can be found in a web search for numerology calculator.
