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

Ran in:
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
