Memory Occupation

A string variable occupies the memory space by (the number of characters + one) bytes, where

the added one byte is used for the character count. That is, it may occupy 2 to 256 bytes.

If a non-array string variable consisting of 20 characters is declared, for example, it will occupy

21-byte memory space.
