I would like to compare to strings and if they are alike write out a number to the scrren like this:

A='thisisastr';

B='anotherstr';

C='anothernot';

aA='anothernot';

bB='thisisastr';

cC='anotherstr';

QQ='something else';

if strcmp(aA,A)

W=1;

elseif strcmp(aA,B)

W=2;

elseif isequal(aA, C)

W=3;

end

if strcmp(bB,A)

U=1;

elseif strcmp(bB,B)

U=2;

elseif strcmp(bB,C)

U=3;

end

if strcmp(cC,A)

Z=1;

elseif strcmp(cC,B)

Z=2;

elseif strcmp(cC,C)

Z=3;

end

Then I would like to write it to the screen:

fprintf('The house is:%d%d%d%s',W, U, Z, QQ);

But I get this error on fprintf:

Unrecognized function or variable 'W'.

Does anyone see where is the mistake please

The code works:

A='thisisastr'; B='anotherstr'; C='anothernot';
aA='anothernot'; bB='thisisastr'; cC='anotherstr';
QQ='something else';
if strcmp(aA,A)
        W=1;
elseif strcmp(aA,B)
        W=2;
elseif isequal(aA, C)
        W=3;
end
if strcmp(bB,A)
        U=1;
elseif strcmp(bB,B)
        U=2;
elseif strcmp(bB,C)
        U=3;
end
if strcmp(cC,A)
        Z=1;
elseif strcmp(cC,B)
        Z=2;
 elseif strcmp(cC,C)
        Z=3;
end
fprintf('The house is: %d%d%d %s',W, U, Z, QQ);
The house is: 312 something else
