title: How to set value of alphabet letter? C++
body: <p>Well, I have to make a task, that will sort elements of array in UNIQUE way.</p>
  
  <p>So, for example, if I input 1st string:
  BOB, I have to do: 2+15+2 (because of their positioning in the alphabet) and then divide by amount of chars /3 and do that for all inputted strings and then sort them by highest to lowest. :)</p>
  
  <p>My question is, how do I set value 1,2,3,4,5... for A,B,C,D,E..... (only big letters).</p>
  
  <p>Thank you.</p>
