Summary

In this chapter, we learned how arrays are homogenous groupings of data types, unlike structures. We then learned how to declare arrays, as well as how to initialize them in various ways, depending on how they were declared. We learned the differences between constant-length arrays and VLAs for initialization and how they are identical in every other way. We saw that we don't always have to specify the size of an array if we initialize it with values when it is declared. Once an array has been declared, its size is fixed and cannot change. We learned how to access array elements via the element's offset, also known as the index or subscript. We further saw how to manipulate the simplest kind of array – a one-dimensional array – directly via the for()… loop, as well as by using arrays as function parameters.

This chapter is a prerequisite to Chapter 12, Working with Multi-Dimensional Arrays, through to Chapter 16, Creating and Using More Complex...
