The following works for numbers:
B=[];
B(1)=10;
but how to make it work for strings such as
C=[''];
C(1)='hello';% does NOT work

Declare an empty string array in this manner:
C=string.empty;
C(1)='hello';
C(2) = 'goodbye';

This is a workaround, but it actually creates a cell array of strings.

"This is a workaround, but it actually creates a cell array of strings. "
At the time this question was posed (and answered) the string class did not exist (it was only introduced in R2016b). Each element of a character array stores only one character, so (until the string class was introduced) the only way to store multiple characters using a scalar index (as the question poses) is to use a cell array. From that persepctive it is not a "workaround", it is the correct solution for versions of MATLAB before R2016b.

You can initialise an empty string array with:
s = strings(0)
to which the response is:
s =
0×0 empty string array
