Introduction
One-dimensional array
Multidimensional array
Advantage of Array
Write a C program using arrays that produces the multiplication of two matrices.
An array is a group of similar elements or data items of the same type collected at contiguous memory locations. In simple words, we can say that in computer programming, arrays are generally used to organize the same type of data.
Array for Integral value:
Array for Integral value
Array for Character value:
Array for Character value
Representation of an Array:
Arrays can be represented in several ways, depending on the different languages. To make you understand, we can take one example of the C language. The picture below shows the representation of the array.
Representation of the array
Arrays always store the same type of values. In the above example:
int is a type of data value.
Data items stored in an array are known as elements.
The location or placing of each element has an index value.
Important: Array can store only the same type of data items. From the below example you can see how it works:
Array work image
In the array a, we have stored all integral values (same type)
In the array b, we have stored all char values (same type)
In the array c, there is integral, float, char all types of values and this is not something an array can store so, option 3 is wrong because an array cannot store different types of values.
Declaration Syntax of Array:
VariableType VariableName[Sequence of Elements];
Example 1: For integral value
int A[10];
Here 10 means, this array A can have 10 integer elements.
2 5 8 44 21 11 7 9 3 1
Example 2: For character value
char B[10];
This array B can have 10 character elements.
f d a b n j l s e y
Initialization of an Array:
If an array is described inside a function, the elements will have garbage value. And in case an array is static or global, its elements will be initialized automatically to 0.
We can say that we can simply initialize elements of an array at the time of declaration and for that, we have to use the proper syntax:
Syntax: datatype Array_Name[size] = { value1, value2, value3, ….. valueN };
Types of Arrays:
There are two types of arrays:
One-Dimensional Arrays
Multi-Dimensional Arrays
One -Dimensional Arrays
A one-dimensional array is a kind of linear array. It involves single sub-scripting. The [] (brackets) is used for the subscript of the array and to declare and access the elements from the array.
Syntax: DataType ArrayName [size];
For example: int a[10];
Multi-Dimensional Arrays
In multi-dimensional arrays, we have two categories:
Two-Dimensional Arrays
Three-Dimensional Arrays
1. Two-Dimensional Arrays
An array involving two subscripts [] [] is known as a two-dimensional array. They are also known as the array of the array. Two-dimensional arrays are divided into rows and columns and are able to handle the data of the table.
Syntax: DataType ArrayName[row_size][column_size];
For Example: int arr[5][5];
2. Three-Dimensional Arrays
When we require to create two or more tables of the elements to declare the array elements, then in such a situation we use three-di

Homework Assignment – Array Technical Document
Write a technical document that describes the structure and use of arrays. The document should
be 3 to 5 pages and include an Introduction section, giving a brief synopsis of the document and
arrays, a Body section, describing arrays and giving an annotated example of their use as a
programming construct, and a conclusion to revisit important information about arrays described
in the Body of the document. Some suggested material to include:
Declaring arrays of various types
Array pointers
Printing and processing arrays
Sorting and searching arrays
Multidimensional arrays
Indexing arrays of various dimension
Array representation in memory by data type
Passing arrays as arguments
If you find any useful images on the Internet, you can use them as long as you cite the source in
end notes.
Solution
Array is a collection of variables of the same type that are referenced by a common name.
Specific elements or variables in the array are accessed by means of index into the array.
If taking about C, In C all arrays consist of contiguous memory locations. The lowest address
corresponds to the first element in the array while the largest address corresponds to the last
element in the array.
C supports both single and multi-dimensional arrays.
1) Single Dimension Arrays:-
Syntax:- type var_name[size];
where type is the type of each element in the array, var_name is any valid identifier, and size is
the number of elements in the array which has to be a constant value.
*Array always use zero as index to first element.
The valid indices for array above are 0 .. 4, i.e. 0 .. number of elements - 1
For Example :- To load an array with values 0 .. 99
int x[100] ;
int i ;
for ( i = 0; i < 100; i++ )
x[i] = i ;
To determine to size of an array at run time the sizeof operator is used. This returns the size in
bytes of its argument. The name of the array is given as the operand
size_of_array = sizeof ( array_name ) ;
2) Initialisg array:-
Arrays can be initialised at time of declaration in the following manner.
type array[ size ] = { value list };
For Example :-
int i[5] = {1, 2, 3, 4, 5 } ;
i[0] = 1, i[1] = 2, etc.
The size specification in the declaration may be omitted which causes the compiler to count the
number of elements in the value list and allocate appropriate storage.
For Example :- int i[ ] = { 1, 2, 3, 4, 5 } ;
3) Multidimensional array:-
Multidimensional arrays of any dimension are possible in C but in practice only two or three
dimensional arrays are workable. The most common multidimensional array is a two
dimensional array for example the computer display, board games, a mathematical matrix etc.
Syntax :type name [ rows ] [ columns ] ;
For Example :- 2D array of dimension 2 X 3.
int d[ 2 ] [ 3 ] ;
A two dimensional array is actually an array of arrays, in the above case an array of two integer
arrays (the rows) each with three elements, and is stored row-wise in memory.
For Example :- Program to fill .
An array is a group of data items of same data type that share a common name. Ordinary variables are capable of holding only one value at a time. If we want to store more than one value at a time in a single variable, we use arrays.
An array is a collective name given to a group of similar variables. Each member in the group is referred to by its position in the group.
Arrays are alloted the memory in a strictly contiguous fashion. The simplest array is a one-dimensional array which is a list of variables of same data type. An array of one-dimensional arrays is called a two-dimensional array.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
