WebThe definition of an array becomes apparent when the mechanics of accessing elements in an array is explained. The minimum data needed to define an array consists of a variable which contains the address of the start of the array, the size of each element, and the space to store the elements. For example, an array based at address 0x10010044 ... WebThe first two (.text and .data) are used to identify sections of an assembly language program. The last two (.data and .word) are used to declare and initialize variables. We will consider additional assembler directives in later labs.
