MATLAB - Cell Arrays and Structures

What is wrong with this code snippet?

student(1).Name = 'Tom';
disp(student(1).Age);
student(2).Age = 20;

AMissing semicolon after first line.

BField 'Age' does not exist for student(1).

CCannot mix different fields in structure array.

Dstudent must be initialized before assignment.

Step-by-Step Solution

Solution:

Step 1: Check field existence for student(1)
student(1) has 'Name' but no 'Age' field assigned yet.
Step 2: disp(student(1).Age) tries to access missing field
This causes an error because 'Age' is undefined for student(1).
Final Answer:
Field 'Age' does not exist for student(1). -> Option B
Quick Check:
Accessing missing field causes error [OK]

Quick Trick: All elements must have same fields to avoid missing field errors [OK]
