# VS 2010 - Calculating Type Of Combinations Of Character

Oct 4, 2010I have a string that can be anywhere from 1 to 8 digits long of which each character is a hex number (0-9, A-F) and each character isn't necessarily unique. I need to calculate all possible combinations. Is there a specific term for this type of calculation or combination? I need to learn how to write a program to "calculate" all the possible combinations.
