Convert word into number

Hello, basically I need a program for my math class that takes a word that is entered and gives it a numerical value. Each letter is assigned a number. E.g. a=1 b=2 c=3 d=4 e=5 f=6 (and so on) then, when the user types ina word, for example "abc", the program adds up a=1 + b=2 + c=3, and outputs the answer, which in this case is 6. I would assume that this program will be extremely simple to make, however I do not have the time, and it is for the staff. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Must run on windows 98 and windows xp
