Question

Operator[] can be overloaded to do what two things:

a) Access elements of an array-like data structure and modify elements
b) Access elements of an array-like data structure and perform arithmetic operations
c) Create new elements in an array-like data structure and delete elements
d) Only access elements of an array-like data structure

Answer 1

The operator[] can be overloaded to access elements of an array-like data structure and modify elements.

Step-by-step explanation:

The operator[] can be overloaded to a) access elements of an array-like data structure and modify elements. This means that you can use the operator[] to retrieve elements from an array-like data structure and then modify those elements. Here is an example:

int myArray[] = {1, 2, 3, 4, 5};

int thirdElement = myArray[2];

myArray[2] = 10;

In the example above, the operator[] is used to access the third element of the array and assign it to the variable thirdElement. Then, the operator[] is used again to modify the third element by assigning it the value 10.

So, the correct answer is a) Access elements of an array-like data structure and modify elements.
