You can simply use your auto increment id column to output according to desired output:

SELECT "C"||id from societe;

Which simply concatenates the desired character and the value from idcolumn, with the help of the || concateneation operator.

After a few insert lines (missing from your mre), the output is:

C0
C1
C2
C3
C4
C5
C6
C7
C8
C9
C10
C11
