It is the programmer's responsibility to stay within the proper bounds.

In particular, you must not let the subscript become negative for above N-1, where N is the size of the array.

Another situation in which an array's size need not be specified is when the array elements are given initial values.

As we will see in Chapter 9, the compiler will determine the size of such an array from the number of initial values. Most obviously, we can write subscripted references to array elements, as we have already seen.

Multi-dimensional arrays require multiple sets of brackets.

The examples in Listing 8-1 are valid declarations.short data[5]; /* define data, allocate space for 5 16-bit integers */ char string[20]; /* define string, allocate space for 20 8-bit characters */ int time,width[6]; /* define time, width, allocate space for 16-bit characters */ short xx[10][5]; /* define xx, allocate space for 50 16-bit integers */ short pts[5][5][5]; /* define pts, allocate space for 125 16-bit integers */ extern char buffer[]; /* declare buffer as an external character array */Notice in the third example that ordinary variables may be declared together with arrays in the same statement.

The statement If the array has two dimensions, then two subscripts are specified when referencing.

As programmers we may any assign logical meaning to the first and second subscripts.

Although arrays represent one of the simplest data structures, it has wide-spread usage in embedded systems.

Strings are similar to arrays with just a few differences.

    So, I will end up with four jobs in array B and three jobs in array A. Later on, I will have to sort them from longest processing times array B and shortest processing times array A. But I'm not 'there" yet. Does anyone have a recommendation as to how I should tackle the array assignment for B and A?…

    This dates to CLU 1974, and CLU helped popularize parallel assignment generally. In C and C++, the comma operator is similar to parallel assignment in allowing multiple assignments to occur within a single statement, writing a = 1, b = 2 instead of a, b = 1, 2.…

    Note Since we assigned the pointer the address of an array of characters, the pointer must be a character pointer--the types must match. Also, to assign the address of an array to a pointer, we do not use the address-of & operator since the name of an array like label behaves like the address of that array in this context.…

    Int *array would be illegal here; the compiler would not accept us assigning the { 45, 67, 89 } initializer to it. This variable, array, is an extra-big box three int s' worth of storage. One neat feature of C is that, in most places, when you use the name array again, you will actually be using a pointer to its first element in C terms.…
