end
end
fprintf('Number of vowels=%d',vowels);
fprintf('Number of consonants=%d',cons);
fprintf('Number of spaces=%d',spaces);
fprintf('Number of numbers=%d',num);
This is my code and I am getting an error at line 11 . Can anyone please help me out and check if there are any other errors?

Hi Aagam
It is my understanding that you are trying to count the number of vowels, consonants, spaces, and numbers in a given string. However, you're getting the error.
This error is occurring because of line 11. There should be an OR (||) operator in-between " strg(i)=='u' " and " strg(i)=='A' ".
Please refer to the https://in.mathworks.com/help/matlab/logical-operations.html (logical operator) documentation for more information on how to use logical operators.

in Matlab, array indices start from '1'

I already tried that it isn't working

In MATLAB, indexing always starts from 1, change the indexing on line:10 to for i = 1:l
