/*******************************************************************/

The variable a has a value of 36
Which represents the ACSII symbol $
The letter A has an ASCII value of 65
And the letter B has an ASCII value of 66

Enter a letter: g
you entered g
thats 103 in ASCII
next char is h

'A' + 'a' = 162

'A' + a = 101
