Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Question

Consider the following declaration of an array of structures:

```plaintext
struct {
char gribble[12];
int word;
short little;
} records[5];

For each of the following variables, give its offset in bytes from the first byte of the array records. Assume x86-64 architecture.

(a) records[0].word _______________
(b) records[0].gribble[1] _______________
(c) records[0].little _______________

Topical Information Use C++. This lab will help you practice with dynamic memory (NOT mixed with classes). Program Information Heat flow through a rod can be simulated fairly easily in a computer program. We can simulate the rod using an array of temperatures. The rod begins all at the same temperature (user determined), but holding some position(s) of the rod at constant temperature (holding a match or ice cube to the rod) provides a [set of] heat source(s) (or sink(s)). To update the temperature at each time step (second?), you take the average of the positions on each side from the previous time step (and at the current position). For instance, if the following was the initial state of the rod: +------+------+------+------+------+------+------+------+ | 10 | 10 | 10 | 10 | 10 | 10 | 10 | 10 | +------+------+------+------+------+------+------+------+ And then the user specifies that there is a heat source at the left end of 100 degrees:…
Please use easy logic with proper indentations and comments for understanding!. Coding should be in C++. 3. Define a class which stores up to 10 integer values in an array. The class should also define the following 4 public methods: setNumber – accepts an integer value to store in the array. The value is stored in the next available element of the array (first call to the method stores the value in element 0 with the second call storing the value in element 1.) The method returns true if there is room in the array and the integer was successfully stored. Returns false otherwise. clear – removes all values from the array so that the array can be reused. displayNumbers – displays the values currently stored in the array. getStats – determines the largest, smallest, and average of the values currently stored in the array. These values are returned to the caller via reference parameters. All methods should produce correct results regardless of the order in which…
