What is the difference between showing and selecting. I assume when I select something it can be manipulated, but I may be wrong. I.e. SHOW columns FROM customers vs. SELECT * FROM customers. Is there a difference?

I have 10 variables called, int1, int2, int 3 and so on. The user can write one number into the console. If the user types 7, I want to add 3 to the value of int7. how do I do this without 10 if statements? can I somehow do something like, (int + "userinput") += 3? thank you for your help! :D
