Array Data Structure. In computer science, an array data structure, or simply an array, is a data structure consisting of a collection of elements (values or variables), each identified by at least one array index or key.An array is stored such that the position of each element can be computed from its index tuple by a mathematical formula. Mahnoor Khan. 36 0 obj Arrays are zero indexed, that is, referring to the array initialization above, the first element of the array is at index 0, hence mySensVals[0] == 2, mySensVals[1] == 4, and so forth.
