An array of characters (or) collection of characters is called a string.
Input and output for strings
Example
Following is the C program for input and output for strings −
#include<stdio.h>
main ( ){
char a[30];
printf("enter your name");
scanf ( "%s",a);
printf ("your name is %s",a);
getch ( );
}Output
When the above program is executed, it produces the following result −
1. Enter your name : Lucky 2. Enter your name : Lucky Lol Your name is Lucky Your name is Lucky
Note −
‘&’ is not used for accepting strings because name of the string itself specifies the base address of the string.
Space is not accepted as a character by scanf( ).
‘\0’ is placed by the compiler at the end.
Example
Following is the C program for using gets ( ) and puts ( ) for reading and writing strings −
#include<stdio.h>
main ( ){
char a[30];
printf ( "enter your name");
gets (a);
printf("Your name is");
puts (a);
}Output
When the above program is executed, it produces the following result −
1. Enter your Name : Lucky 2) Enter your name : Lucky Lol Your name is Lucky Your name is Lucky Lol
Note − Space is also accepted as a character by gets ( ).
