Programming in C++, 2nd Edition

512 Arrays

It tells the compiler that ‘a’ is an integer type of array, and it should store five integers. In this

example, 5 is the subscript enclosed within square brackets. The compiler reserves two bytes of

memory for each integer array element; that is, 10 bytes are reserved for storing five integers in

the memory.

In the same way, arrays of different data types are declared as follows:

One-dimensional Array Declaration

char ch[10];

float real[10];

long num[5];

The array initialization is done as follows:

Array Initialization

int a[5] = {1,2,3,4,5};

Here, five elements are stored in an array ‘a’. The array elements are stored sequentially in sepa-

rate ...
