8. Array
C++ provides a data structure, the array, which stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

9. declare
To declare an array in C++, the programmer specifies the type of the elements and the number of elements required by an array as follows −
type arrayName [ arraySize ];
double balance[10];

10. Initializing Arrays
You can initialize C++ array elements either one by one or using a single statement as follows −
double balance[5] = {1000.0, 2.0, 3.4, 17.0, 50.0};

11. If you omit the size of the array, an array just big enough to hold the initialization is created. Therefore, if you write −
double balance[] = {1000.0, 2.0, 3.4, 17.0, 50.0};

12. #include <iostream>
using namespace std;
int main () {
int n[ 3 ]={1,2,3};
cout<< n[1];
return 0; }

13. String
The C-style character string originated within the C language and continues to be supported within C++. This string is actually a one- dimensional array of characters which is terminated by a null character '\0'.
Thus a null-terminated string contains the characters that comprise the string followed by a null.

14. char greeting[6] = {'H', 'e', 'l', 'l', 'o', '\0'};

16. #include <iostream>
using namespace std;
int main () {
char greeting[6] = {'H', 'e', 'l', 'l', 'o', '\0'};
cout << "Greeting message: ";
cout << greeting << endl;
return 0; }

17. Pointers
C++ pointers are easy and fun to learn. Some C++ tasks are performed more easily with pointers, and other C++ tasks, such as dynamic memory allocation, cannot be performed without them.

18. #include <iostream>
using namespace std;
int main () {
int var1;
char var2[10];
cout << "Address of var1 variable: ";
cout << &var1 << endl;
cout << "Address of var2 variable: ";
cout << &var2 << endl;
return 0; }
