Which index is constant in column major traversal when accessing data for a specific student?

• Both indices

• Row index

• Column index

• No index

What is the result of a column major traversal?

• Values by row

• Values by column

• Random values

• No specific order

What does the outer loop represent in a nested loop used for row major traversal?

• None

• Specific value

• Row

• Column

How does swapping row and column indices affect traversal in a 2D array?

• Changes to column major

• Changes to row major

• Error in traversal

• No change

What type of loop is recommended for accessing each array within a 2D array?

• For loop

• Do-while loop

• Enhanced for loop

• While loop

Which method is used to find specific elements within a 2D array?

• Hash map

• Tree search

• Binary search

• Linear search

What is initialized before the nested loops when checking for a particular property in array elements?

• Index pointer

• Tracker value

• Counter

• Sum variable
