Copyright © 2012 Pearson Education, Inc. Q: Define an array? An array is a variable that can store multiple values of the same type Q: Write a format for declaring a one dimensional array? EX: int tests[5]; [ Array Size declarator] ;

Copyright © 2012 Pearson Education, Inc. Q: Design an array - Memory Layout for the following array int tests[5]; allocates the following memory: Subscripts first element second element third element fourth element fifth element

Copyright © 2012 Pearson Education, Inc. Array Terminologies Q: What is the difference between the array size declarator and the array size ? The array size declarator shows the number of elements in the array. The size of an array is the total number of bytes allocated for it. It is = (number of elements) * (number of bytes for each element)

Copyright © 2012 Pearson Education, Inc.. Q: Calculate the size of these arrays? 1. int tests[5] is an array of 20 bytes, assuming 4 bytes for an int 2.long double measures[10] is an array of 80 bytes, assuming 8 bytes for a long double
