String

String :-
A String is nothing but a collection of Characters.

Syntax :- 

data type variable name[size]
char String[size];

Character data type	String data type
char a=’x’;	char a[size]; char a[20];

Ex:-

char name[10];

0	1	2	3	4	5	6	7	8	9

P	R	A	S	A	D	\0	\0	\0	\0
0	1	2	3	4	5	6	7	8	9

In the above example we can store only 9 characters remaining one character is Null characters'\0'.

Data type	Format specifier
Character data type	%C
String data type	%S

* Write a Program to Print your Name with out String.

#include<stdio.h> #include<conio.h> void main()       {             char a=’p’,b=’r’,c=’a’,d=’s’,e=’a’,f=’d’;             clrscr();             printf(“%c%c%c%c%c%c”,a,b,c,d,e,f);             getch();        }

Output:-

prasad

* Write a Program to Print your Name using one variable.

#include<stdio.h>  #include<conio.h>  void main()          {               char name;               clrscr();               printf("enter your name:");               scanf("%c",&name);               printf("your name is :%c",name);               getch();          }

Output:-

Enter your name: prasad  Your name is: p

To the above program we gave a name,in that only one Character will be print. 

Because Variable can store only one Character. 

If we want to store number of Characters in one Variable we have to create String.

* Write a Program to Print your Name using String.

#include<stdio.h>  #include<conio.h>  void main()        {             char name[20];             clrscr();             printf("enter your name");             scanf("%s",&name);             printf("your name is :%s",name);             getch();        }
