MATLAB - String Handling

The following MATLAB code is intended to concatenate 'Hi' and 'There' but causes an error. What is the error and how to fix it?

str1 = 'Hi';
str2 = 'There';
result = str1 + str2;
disp(result);

ANo error, output is 'HiThere'

BError: Use strcat function instead of +

CError: Use & operator instead of +

DError: Use square brackets [ ] instead of + for concatenation

Step-by-Step Solution

Solution:

Step 1: Identify the cause of error
Using + operator between strings in MATLAB causes an error because + is not defined for character arrays.
Step 2: Correct the concatenation method
Replace + with square brackets [ ] to join strings: result = [str1 str2];
Final Answer:
Error: Use square brackets [ ] instead of + for concatenation -> Option D
Quick Check:
Concatenate strings with [ ], not + [OK]

Quick Trick: Replace + with [ ] to fix string concatenation error [OK]
