The following will take x consecutive chars in memory:

'n' - 1 char (type char) "n" - 2 chars (above plus zero character) (type const char*) '\n' - 1 char "\n" - 2 chars "\\n" - 3 chars ('\', 'n', and zero) "" - 1 char

The following will take x consecutive chars in memory:

'n' - 1 char (type char) "n" - 2 chars (above plus zero character) (type const char[2]) '\n' - 1 char "\n" - 2 chars "\\n" - 3 chars ('\', 'n', and zero) "" - 1 char

but:

sizeof("n") will not be equal to 2 (only if sizeof(const char*) == 2)
