Inserting a space when printing characters using fprintf

I have an array of characters assigned to variable m20 in the format of

CGNU
AEOS
NRRA

I am supposed to have a printed output of 'CAN GER NOR USA' but I am getting 'CANGERNORUSA' with the following code

 fprintf('Countries with at least 20 medals: %s \n',m20)

if I were to add 5.0 infront of the %s placeholder, my outputs just vanishes instead of printing.

How can I insert space after printing 3 characters?

Str = ['CGNU'; ...
       'AEOS'
       'NRRA'];
CStr = cellstr(Str.');  % Transposing is important
fprintf('Countries with at least 20 medals:');
fprintf(' %s', CStr{:});  % Or: fprintf(' %c%c%c', Str)
fprintf('\n')

You must have stripped out the spaces in m20 before printing. Either add spaces back into m20 before printing or change print statement to this:

fprintf('Countries with at least 20 medals: %3s %3s %3s %3s\n',m20(1:3), m20(4:6), ... 
m20(7:9), m20(10:12));

@Linggeas Kisten — Please learn to use the [{}Code] button to format your code. That will help significantly.

I formatted it for you, but not in time for ‘Mark M’ to benefit from it.

m20 = ['CGNU'
       'AEOS'
       'NRRA'];

fprintf('Countries with at least 20 medals: ')

fprintf(1,'%c%c%c ', m20)
fprintf('\n')

Countries with at least 20 medals: CAN GER NOR USA
