Question

Which of the following code fragments will access the lastname data member of the teammate at index 0? Select all that are correct.

Answer 1

To access the 'lastname' data member of the teammate at index 0, one would typically use 'team[0].lastname;' for an object in an array, or 'team[0]['lastname'];' for an associative array or dictionary, with syntax varying by language.

Step-by-step explanation:

To access the lastname data member of the teammate at index 0 from a given array or list, the correct code fragment will depend on the programming language in use. However, a common way to access a property of an object in an array in many programming languages such as JavaScript, Java, or Python would be:

team[0].lastname;

or, if the data structure is an associative array or a dictionary:

team[0]['lastname'];

In both cases, you are accessing the first element of the array (since arrays are zero-indexed) and then accessing its lastname property. Note that the exact syntax may vary depending on the language and the structure of the array or list.
