scriptarr.m:

mycell = {'the',' ','cow',' ','jumped',' ','over',' ','the',' ','moon'};
fprintf("The string at mycell{7} is: %s\n",mycell{7});
%access and print string contained in cell at index 7

fprintf("The odd indexed elements in cell array are: \n");
%access and print string contained in odd indices
for i = 1:11
    if mod(i,2)!=0
        fprintf("mycell{%d}: %s\n",i,mycell{i});
    end
end

fprintf("The even indexed elements in cell array are: \n");
%access and print string contained in odd indices
for i = 1:11
    if mod(i,2)==0
        fprintf("mycell{%d}: %s\n",i,mycell{i});
    end
end
fprintf("The string at mycell{5} is: %s\n",mycell{5});
%access and print string contained in cell at index 5

fprintf("The string at mycell{5} is: %c\n",mycell{5}(end));
%access and print last character of string contained in cell at index 5

newmycell = {1,2;'helllo','hi';9.0,7.8};
%creating new cell with atleast 3 datatypes
display(newmycell{1,2});
%accessing 2 from given newmycell
