Question

The enhanced for loop

Select one:
a. is convenient for traversing all elements in an array
b. is convenient for traversing elements in a partially filled array
c. is only used for arrays of integers
d. is used to initialize all array elements to a common value

Answer 1

The enhanced for loop is most convenient for traversing all elements in an array, and it works with any type of data, not just integers. It is not designed to initialize array elements or to only loop through parts of an array. The correct answer is a. is convenient for traversing all elements in an array.

Step-by-step explanation:

The student has asked which statement is correct about the enhanced for loop. The right answer is that the enhanced for loop is convenient for traversing all elements in an array. It is a specialized loop construct that allows iterating through each element in an array or a collection without the need for a counter or an index variable.

An enhanced for loop cannot be used to initialize array elements to a common value, nor is it constrained to arrays of integers—it works with any data type. Also, it is not the best choice for traversing partially filled arrays where not all elements contain relevant data, as it will go through all elements including the uninitialized or default ones. Therefore, the correct answer is a. is convenient for traversing all elements in an array.
