The function CHAR_TO_CODE('a') evaluates to 97, the ASCII value of the character ‘a’.

       CODE_TO_CHAR(97) evaluates to 'a'.

            State what is output by this algorithm:

x ← CHAR_TO_CODE('b')

The function CHAR_TO_CODE('a') evaluates to 97, the ASCII value of the character ‘a’.

       CODE_TO_CHAR(97) evaluates to 'a'.

            State what is output by this algorithm:

y ← x + 1

The function CHAR_TO_CODE('a') evaluates to 97, the ASCII value of the character ‘a’.

       CODE_TO_CHAR(97) evaluates to 'a'.

            State what is output by this algorithm:

z ← x – 1 

The function CHAR_TO_CODE('a') evaluates to 97, the ASCII value of the character ‘a’.

       CODE_TO_CHAR(97) evaluates to 'a'.

            State what is output by this algorithm:

w ← CODE_TO_CHAR(y) + CODE_TO_CHAR(z)

The function CHAR_TO_CODE('a') evaluates to 97, the ASCII value of the character ‘a’.

       CODE_TO_CHAR(97) evaluates to 'a'.
