Arrays allow storing of a collection of related data under a single variable name. There are different types of arrays including one-dimensional, two-dimensional, and multi-dimensional arrays. One-dimensional arrays use a single subscript, two-dimensional arrays use two subscripts for rows and columns, and multi-dimensional arrays can use more than two subscripts. Arrays in C can be initialized at compile-time or run-time. Common operations on arrays include reading and writing elements, concatenation, comparison and more. C provides functions like strlen(), strcat(), strcmp() for string handling and manipulation.

It describes common string operations like searching, sorting, trimming, insertion, and deletion. It also lists various string manipulation functions in C like strcat, strcpy, strlen, and their applications in areas like text editing, search engines, and computational biology.
Arrays allow storing multiple values of the same type sequentially in memory. An array is declared with the type, name, and size. Elements are accessed using indexes from 0 to size-1. Strings are represented as character arrays terminated with a null character. Arrays can be passed to and returned from functions, and multidimensional arrays store arrays within arrays. Standard libraries provide functions for string and character manipulation.
A pointer is a variable that stores the address of another variable. Pointers allow a variable to indirectly access and modify the value of another variable. Pointers contain the address of the variable they point to. Common string operations like finding the length, comparing, copying and concatenating strings can be performed using standard library functions like strlen(), strcmp(), strcpy(), and strcat(). These functions make string handling easier compared to writing custom code.
Arrays allow programs to store and manipulate multiple values of the same type. An array defines a list of elements of the same data type, accessed using an index. One-dimensional arrays use a single index, while multi-dimensional arrays use multiple indices. Arrays are defined with a type, name, and size, such as int arrayName[size]. Individual elements are accessed using indices, such as arrayName[index]. The document provides examples of one-dimensional and two-dimensional arrays in C programming language and exercises manipulating arrays.
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.
The document discusses arrays and pointers in C programming. It defines arrays as homogeneous data types that allow a group of data items to be accessed using a single name and index. The document describes properties of arrays like type, length, and size. It also discusses initialization of one-dimensional and two-dimensional arrays. The document also covers strings as character arrays and functions in C including parameter passing, return values, and different types of functions.
MATLAB allows for the creation and manipulation of character strings. Strings can be defined using single quotes and treated as character arrays. Strings can be combined vertically using concatenation or char, and horizontally using concatenation, strcat, or by converting to a cell array of strings using cellstr. MATLAB contains many string functions for tasks like formatting, comparison, searching/replacing, and more.
Unit III discusses strings in C programming. Strings are represented as arrays of characters that are stored in contiguous memory locations. Common string functions like gets(), puts(), printf() are explained. gets() accepts a string from the user and puts() displays a string. printf() can display strings with format specifiers. The atoi() function converts a string to an integer.

Character Arrays & Strings
Introduction
A string is a sequence of characters. Any sequence or set of characters defined within double
quotation symbols is a constant string. In c it is required to do some meaningful operations on strings
they are:
Readingstringdisplayingstrings
Combiningorconcatenatingstrings
Copyingone stringtoanother.
Comparingstring& checkingwhethertheyare equal
Extractionof a portionof a string
8. 8
Declaring & InitializingStringVariables
char month1[ ]={‘j’,’a’,’n’,’u’,’a’,’r’,’y’};
Thenthe string monthisinitializing to January. This is perfectly valid but C offers a special way
to initialize strings.
The above string can be initialized as
char month1[]=”January”;
The characters of the stringare enclosedwithinapartof double quotes.The compilertakescare
of stringenclosedwithina pair of double quotes. The compiler takes care of storing the ASCII codes of
characters of the string in the memory and also stores the null terminator in the end.
/*String.c string variable*/
#include < stdio.h >
#include<conio.h>
voidmain()
{
char month[15];
printf (“Enterthe string”);
gets(month);
printf (“The stringenteredis%s”,month);
}
0 specifies a single character whose ASCII value is zero.
J A N U A R Y 0 ? ? ? ? ? ? ?
Character string terminated by a null character ‘0’.
A string variable is any valid C variable name & is always declared as an array.
syntax
char string_name[size];
9. 9
The size determines the number of characters in the string name.
Example:
char address[100];
The size of the array should be one byte more than the actual space occupied by the string since the
complier appends a null character at the end of the string.
Reading Strings from the terminal:
The function scanf with%s format specification is needed to read the character string from the
terminal.
Example:
char address[20];
scanf(“%s”,address);
->Scanf statement has a draw back it just terminates the statement as soon as it finds a blank space,
suppose if we type the string new york then only the string new will be read and since there is a blank
space after word “new” it will terminate the string.
->The function getchar can be used repeatedly to read a sequence of successive single characters and
store it in the array.
We cannotmanipulate stringssince Cdoesnotprovide anyoperatorsfor string. For instance we cannot
assign one string to another directly.
For example:
String=”xyz”;
String1=string;
are notvalid.To copythe chars inone string to another string we may do so on a character to character
basis.
10. 10
Reading a Line of Text
To read a line of text with white spaces, we have a special format specifier %[..] called “Edit set
conversion code” that can be used to read a line containing a variety of characters.
Example: To terminate a string only when a ‘n’ (New Line) character is inserted, we need to give the
following statement:
scanf(“%[^n]”,str);
Here, str – string variable
^n – Describes terminate the reading when ‘n’ character is encountered
Using getchar and gets Function
getchar() function is used to read a single character from the terminal. By providing a loop to
read characters until we provide a newline character, we are facilitating the reading of a line of text.
Example:
int c;
char character;
….
c = 0;
do
{
character = getchar();
line[c++] = character;
}while(character != ‘n’);
11. 11
We may also use the gets() function present in <stdio.h> header file to read a line of text. It is in the
form:
gets(str);
Example:
char line[80];
gets(line);
Writing Strings to Screen
Using printf() function
The format specifier %s can be used to display an array of characters that is terminated by null
(0) character.
Example:printf(“%s”, name);
We can also specify the precision. Example:
%10.4s
Indicatesthatfirstfourcharacters are to be printedin a field width of 10 columns. Including a –
(minus) sign immediately after the % symbol will print the content left-justified.
For variable specification of width and precision, we use the * symbol. Example:
printf(“%*.*s”,w,s,str);
Using putchar() and puts()
We can use the putchar() function repeatedly to print a string to the screen.
Example:
Void main()
{
char name[6] = “paris”;
for(i=0;i<5;i++)
12. 12
putchar(name[i]);
putchar(‘n’);
getch();
}
Another convenient way of printing a string to screen is using puts() function present in <stdio.h>.
Example:
puts(line);
Arithmetic operations on characters:
We can alsomanipulate the charactersaswe manipulate numbersinclanguage.Whenever the system
encountersthe character data it is automatically converted into a integer value by the system. We can
represent a character as a interface by using the following method.
x=’a’;
Printf(“%dn”,x);
Will display 97 on the screen. Arithmetic operations can also be performed on characters for example
x=’z’-1; is a valid statement. The ASCII value of ‘z’ is 122 the statement the therefore will assign 121 to
variable x.
It is also possible to use character constants in relational expressions for example
ch>’a’ && ch < = ’z’ will check whether the character stored in variable ch is a lower case letter.
A character digit can also be converted into its equivalent integer value suppose un the expression
Void main()
{
char character=’8’;
int a;
a=character-‘1’;
13. 13
printf(“%d”,a);
getch();
}
where a is defined as an integer variable & character contains value 8 then a= ASCII value of 8 ASCII
value ‘1’=56-49=7.
We can also get the support of the c library function to converts a string of digits into their equivalent
integer values the general format of the function in
x=atoi(string);
here x is an integervariable &stringis a character array containing string of digits. For example
string=“101”; it will be stored as numeral 101 to x.
Putting Strings Together
We cannot apply the arithmetic addition for joining of two or more strings in the manner
string1 = string2 + string3; or
string1 = string2 + "SACY";
For carrying out the above we need to write a program to copy the contents of the string2 &
string3 into string1 one after the other. This process is called concatenation of strings.
strcat() Function
strcat() joins two or more strings together. It takes the following form
strcat(string1, string2);
string1 and string2 are character arrays. When the above function is executed, string2 is
appendedtostring1. It does so by removing the null character at the end of string1 and placing string2
from there. The string at string2 remains unchanged.
strcat function may also append a string constant to a string variable. The following is valid
14. 14
strcat(part1,"SACY");
C also permits nesting of strcat functions. For example
strcat(strcat((string1,string2),string3);
is allowed and concatenates all the three strings together. The resultant string is stored in
string1.
String Handling Functions
C language recognizesthatstringisa differentclassof array bylettingusinput and output the array as a
unitand are terminatedbynull character.Clibrarysupportsa large numberof string handling functions
that can be used to array out many o f the string manipulations such as:
Length (number of characters in the string).
Concatentation (adding two are more strings)
Comparing two strings.
Substring (Extract substring from a given string)
Copy(copies one string over another)
To do all the operations described here it is essential to include<string.h> library header file in the
program.
strlen() function:
Thisfunctioncountsand returnsthe numberof charactersin a string.The lengthdoes not include a null
character.
Syntax: n=strlen(string);
Where n is integer variable. Which receives the value of length of the string.
15. 15
Example
length=strlen(“Hollywood”);
The function will assign number of characters 9 in the string to a integer variable length.Result is
length=9.
strcat() function:
when you combine two strings, you add the characters of one string to the end of other string. This
processiscalledconcatenation. The strcat() functionjoins2stringstogether.Ittakesthe following form
strcat(string1,string2)
string1 & string2 are character arrays. When the function strcat is executed string2 is appended to
string1. the string at string2 remains unchanged.
Example
#include<stdio.h>
#include<conio.h>
#include<string.h>
Void main()
{
strcpy(string1,”sri”);
strcpy(string2,”Bhagavan”);
Printf(“%s”,strcat(string1,string2);
getch();
}
16. 16
From the above program segment the value of string1 becomes sribhagavan. The string at str2
remains unchanged as bhagawan. Result string1= sribhagavan
strcmp function:
In c you cannot directly compare the value of 2 strings in a condition like:
if(string1==string2)
Most librarieshowevercontainthe strcmp() function,whichreturnsazeroif 2 strings are equal,
or a non zero number if the strings are not the same. The syntax of strcmp() is given below:
strcmp(string1,string2)
String1 & string2may be stringvariablesorstringconstants.String1,& string2may be stringvariablesor
stringconstants some computers return a negative if the string1 is alphabetically less than the second
and a positive number if the string is greater than the second.
Example:
#include<stdio.h>
#include<conio.h>
#include<string.h>
Void main()
{
strcmp(“Newyork”,”Newyork”);//will return zero because 2 strings are equal.
strcmp(“their”,”therr”);//willreturna9 whichis the numeric difference between ASCII ‘i’ and ASCII ’r’.
strcmp(“The”, “the”)// will return 32 which is the numeric difference between ASCII “T” & ASCII “t”.
getch();
}
strcmpi() function
This function is same as strcmp() which compares 2 strings but not case sensitive.
17. 17
Example :
#include<stdio.h>
#include<conio.h>
#include<string.h>
Void main()
{
strcmpi(“THE”,”the”);// will return 0.
getch();
}
strcpy() function:
C does not allow you to assign the characters to a string directly as in the statement name=”Robert”;
Insteaduse the strcpy(0functionfoundinmostcompilersthe syntax of the functionisillustratedbelow.
strcpy(string1,string2);
Strcpy function assigns the contents of string2 to string1. string2 may be a character array variable or a
string constant.
Example:
#include<stdio.h>
#include<conio.h>
#include<string.h>
Void main()
{
strcpy(Name,”Robert”);
getch();
}
In the above example Robert is assigned to the string called name. Result:Name=Robert.
