I need to find the total number of '/' and 'X' characters in my cell array and store the values in variables called num_strikes nad num_spares.
When I run the code below, I get this:
Undefined function 'eq' for input arguments of type 'cell'.
Error in solution (line 6) if bowling(k)=='/'
bowling=cell(1,2)
bowling= {{7,2,8,'/',6,2,'X',9,'/',9,0,'X','X',8,1,7,'/',9}, {'X',9, '/','X',8,'/','X','X',7,2,'X',8,'/',9,0}}
k=0;
num_strikes=0;
for k=1:length(bowling)
if bowling(k)=='/'
k=k+1
num_strikes=k
end
end
disp(num_strikes)

num_spares = sum(strcmp([bowling{:}],'/'));
num_strikes = sum(strcmp([bowling{:}],'X'));
disp(num_spares);
