Creating structure array that accumulates

How do you create a structure array such that the structure array has five fields that are initially empty then more entries are entered to make the structure array a 1x2 structure? For example, the array has fields: field1, field2, field3, field4, field5. And the first entry is empty. The next command adds another entry with value1,value2,value3,value4,and value5. Basically, the following entries will result in an accumulation of entries. I want to create a function that builds on itself.

Preferably, I would like to see how this is done without if-else statements.

Thank you in advance!

You could just pay attention to the answers that were already given to you, e.g. here where I spent time carefully explaining a couple approaches to you:

https://www.mathworks.com/matlabcentral/answers/359170-function-with-a-structural-array

and then here for the same question later:

https://www.mathworks.com/matlabcentral/answers/359385-2x1-structure-array-to-structure-array

where you can see in the comments under your question that both James and I are wondering why you didn't pay attention to the first answer.

S = struct ;
% marks in three subjects
S.Maths= [];
S.Physics = [] ;
S.Chemsitry = [] ;
%%five students marks
for i = 1:5
    S(i).Maths= rand*100;
    S(i).Physics = rand*100 ; 
    S(i).Chemsitry = rand*100 ;

end
