MATLAB - String Handling

Which of the following MATLAB statements correctly concatenates the strings 'Data' and '123'?

Astr = 'Data' + '123';

Bstr = strcat('Data', 123);

Cstr = ['Data' '123'];

Dstr = 'Data' & '123';

Step-by-Step Solution

Solution:

Step 1: Check syntax for string concatenation
In MATLAB, concatenation uses square brackets [ ] for character arrays or strings.
Step 2: Evaluate each option
str = ['Data' '123']; uses ['Data' '123'] which correctly joins the two strings. str = 'Data' + '123'; uses + which is invalid. str = strcat('Data', 123); uses strcat but passes a number without converting it to string. str = 'Data' & '123'; uses & which is invalid.
Final Answer:
str = ['Data' '123']; -> Option C
Quick Check:
Concatenate strings with [ ] brackets [OK]

Quick Trick: Use [ ] brackets to join strings, not + or & [OK]
