Array Fundamentals Quiz

An array is a data structure that can store a fixed-size sequential collection of elements of the same type. It is useful to use an array instead of individual variables when you need to store a collection of data of the same type, such as storing a list of student grades or a set of coordinates in a 2D plane.

A specific element in an array is accessed by an index, which represents the position of the element in the array. The index is significant because it allows for the retrieval and manipulation of individual elements within the array.

All arrays consist of contiguous memory locations. The lowest address corresponds to the first element and the highest address to the last element. Elements are stored in consecutive memory locations based on their index.

<p>To declare an array in C, a programmer specifies the type of the elements and the number of elements required by an array as follows: type arrayName [ arraySize ];. This is called a single-dimensional array, and the arraySize must be an integer constant greater than zero.</p> Signup and view all the answers
