About String in C

 

String in C programing


String is a sequence or a group of characters. The char type variable is capable of storing a single character while the character array is capable of storing the group of characters.
So,string is just a character array.

The general form of string declaration is ,

char stringname[size of array];
e.g. 
char s[50];

String in C programing String is a sequence or a group of characters. The char type variable is capable of storing a single character while the character array is capable of storing the group of characters. So,string is just a character array.


This statement will declare the character array capable of storing the 50 characters.
Initialization of string 
To initialize the string there are two ways,

(a) char str[5]={'a','j','a','y','\0'};
 In this case , all the characters are enclosed in the single quotes and are given within the Curley braces separated by comma.
'\0' is the NULL character and is used to end the string.

(b) char s[5]="ajay";

When the string is initialized by enclosing the group of  characters in the double quotes , the   '\0' or NULL character will automatically get inserted.

Reading and Displaying the strings : 
To read and display the string we will again used the scanf( ) and printf( ) functions respectively, but the format specifier will be %s.
