[Solved] Consider the code:C = {1, 2, 3};val = C(2);disp(val + 1);What is the error in this code? — Ans: Cannot add 1 to a cell array; use curly braces to get content. | MATLAB

MATLAB - Cell Arrays and Structures

Consider the code:

C = {1, 2, 3};
val = C(2);
disp(val + 1);

What is the error in this code?

ACannot add 1 to a cell array; use curly braces to get content.

BIndexing with parentheses is invalid syntax.

CThe cell array C is not defined properly.

Ddisp cannot display numeric values.

Step-by-Step Solution

Solution:

Step 1: Identify the type of val after indexing
val = C(2); uses parentheses, so val is a 1x1 cell array, not a number.
Step 2: Understand why adding 1 causes error
Adding 1 to a cell array is invalid. To add 1 to the content, use curly braces: val = C{2};
Final Answer:
Cannot add 1 to a cell array; use curly braces to get content. -> Option A
Quick Check:
Parentheses return cell, cannot add number [OK]

Quick Trick: Add numbers only to content, not cells [OK]

Common Mistakes:

Using parentheses when curly braces needed
Assuming disp cannot show numbers
Thinking parentheses indexing is syntax error
