In this program, an array num of type int is used to store the given integer numbers and variable nelem to store their count. First, the value of nelem is read. Then a for loop is used to read the given numbers and store them in array num. Finally, another for loop is used to print the given numbers in reverse order.

An array is an array of anything. A string is a specific kind of an array with a well-known convention to determine its length.

This feature can be used with arrays as well. A static array has the following characteristics:

Declaration of arrays, Initialization of arrays, Multi dimensional Arrays, Elements of multi dimension arrays and Initialization of multidimensional arrays. The C language provides a capability that enables the user to define a set of ordered data items known as an array.

For two vectors a and b having n elements each, the addition operation yields a vector (say c) of size n. The ith element of the result vector is obtained by adding the corresponding vector elements, i.e., ci =ai+ bi. The algorithm to perform the desired addition is given below.

An array is a powerful and easy-to-use data structure provided in the C language. We know that arrays provide easy access to their elements and entire arrays can be manipulated easily using loops. However, there are some drawbacks/limitations of arrays:

A three-dimensional array is that array whose elements are two-dimensional arrays. In practice, it may be considered to be an array of matrices. A three-dimensional array with int elements may be declared as below.

Any operation on an array has to be carried out element by element. It cannot be performed on the array as a whole. Therefore, in swapping also, an element of one array is swapped with an element of another array. The two may not have the same index value if you are not dealing with vectors and matrices.

The amount of memory an array can consume depends on the data type of an array. In DOS environment, the amount of memory an array can consume depends on the current memory model (i.e. Tiny, Small, Large, Huge, etc.).

Pointers and Arrays : Data objects in an array can be referenced through pointers instead of using array subscripts. The data type of such a pointer is referred to as "pointer to array of type". The array name itself behaves like a pointer, so there are several alternative methods to accessing array elements. For example :

Initializing Arrays : Arrays are initialized with a brace-enclosed list of constant expressions. A list of initializers for an incomplete array declaration completes the array's type and completely defines the array size.

The maximum or minimum value may be determined by comparing the values of array elements. Let us assume that the maximum value is represented by 'max'. The value of the first element of the array is assigned to max.

When a program containing an array of size n is compiled, the compiler allocates n blocks of memory for the array for storing the values of its elements. The size of each block depends on the data type of the array. For example, for the array AR [ ] defined below, five blocks of memory are allocated and each block is of the size of the memory block for an integer (i.e., 4 bytes on a 32-bit system).

Array Declaration

Every array is given a name. The rules for naming arrays are the same as those used for variable names. As with scalar variables, an array must be declared before it is used. The declaration of a one-dimensional array takes the following form:
