A more interesting casting option is converting a char to a number type, or the other way around. Just like before, you have to be careful how you set this up. In the back-end, a char doesn’t store 'a', it stores the value representing that: 97 for lowercase and 65 for uppercase.
Now targetInt equals 97.
When you cast an int to a char, you get the opposite process and the char is set to the value at the int value. So if you did:
targetChar now equals 'A'.
Instructions
If 'a' is 97, what do you suppose we would get if we set an int to 99 and cast it to a char? Let’s find out. The initial state is set so you need to cast our sourceInt to targetChar.
Set targetChar equal to sourceInt and explicitly cast it by using (char).
Now let’s see what happens when you cast a double into a char. Set targetChar to sourceDouble using implicit casting (no type identifier for the cast).
