Using an apostrophe with fprintf

How do I include an apostrophe within my text while using the fprintf command? For example, fprintf('Avogadro's constant is 6.022e+23 molecules/mole.\n') will not work because the apostrophe in "Avogadro's" ends the text segment.

Use a double single quote character to print a single quote character:

fprintf('Avogadro''s constant is 6.022e+23 molecules/mole.\n')

Use double apostrophe just as you would in any matlab string:

   fprintf('Avogadro''s constant is 6.022e+23 molecules/mole.\n')
