The procedure of passing more than one arrays to a function is similar to the case of passing a single array. This is illustrated in Program.

Program sorts the integers in ascending order by using *insertion method. *The process of sorting starts with picking the second element which is arranged with respect to the first in the specified order (ascending or descending order).

Suppose, we want to sort an array in ascending order. The elements with higher values will move back, while elements with smaller values will move to the front; the smallest element will become the 0th element and the largest will be placed at the end. The mechanism of sorting is explained below.

Each element of an array is a variable of the type declared for the array. Thus, if an array is declared as int Array [n],all its n elements are of type int, and all the operations that can be done on variables of type int may be carried out on the elements of this array. The same holds for arrays of types float, double, and char. In Program integer array elements are subjected to arithmetic operations.

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).

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.*

In case of large arrays, the method of comparing every array element with key as described above is rather inefficient. However, if an array is a sorted one, the search process can be considerably shortened by using *binary search *method. For the application of binary search the array should be first sorted.

Searching an array for a value is the most common occurrence in programming as well as in real life. Often it is required to search a name in a list of names or search a roll number in a list of roll numbers.

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.

An array is similar to a list in which the objects are of the same type and stored in sequential memory blocks; this is the only relationship between the elements of an array. The input/output of values of elements of an array cannot be done as whole of array, but is carried out element by element. This may be done by accessing each element by its index value. Therefore, for large arrays, either a *for *loop or a *while *loop may be used for accessing each element for its input/output. For example, if elements of an array Array [4] having 4 elements are to be processed for input /output by user of a program, the program code may be written as follows:

As we know, a pointer to type T is analogous to an array of type T.A pointer can be used to represent a vector, as illustrated in Fig. When a pointer is declared, the memory is allocated only for the pointer variable. The memory for the array elements is usually allocated separately using dynamic memory allocation functions, namely, malloc or calloc.

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:

When we declare a pointer, it does not point to any specific variable. We must **initialize **it to point to the desired variable. This is achieved by assigning the address of that variable to the pointer variable, as shown below.

C language permits the use of **multidimensional arrays. **It is easy to visualize arrays up to three dimensions. However, we may have difficulty in visualizing a four, five or in general, an n-dimensional array.

A **two-dimensional array **(commonly called a ** matrix) **consists of elements of the same type arranged in rows and columns. The rows and columns of a matrix are numbered starting from 0. Thus, for an array of size

As in case of scalar variables, we can also use external or global arrays in a program, i. e., the arrays which are defined outside any function. These arrays have global scope.

In the HSC examination, there are six subjects each having a maximum of 100 marks. To pass the examination, a student has to score at least 35 marks in each subject. If a student passes, total marks and percentage marks are calculated and a class is awarded based on the percentage marks (perce)as follows:

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., c* _{i} =a_{i}+ b_{i}. *The algorithm to perform the desired addition is given below.

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.
