Array of Characters (Strings)
C Programming
In general, a strings in a sequence of character treated as one unit. A string constant is a one dimensional array of characters terminated by a null ('\0') character.
ARRAY OF CHARACTERS (STRINGS)
In
general, a strings in a sequence of character treated as one unit. A string
constant is a one dimensional array of characters terminated by a null ('\0')
character.
Example:
char
name[ ] = {'V', 'R', 'B', '\0'};
Where,
'\0' is a null character and specifies end of the string. Terminating the
string with null '\0' is important, because it is the only way the functions
that work with a string can know where the string ends.
The
last character is called '\0' null character, it looks like two characters but
it is actually one character. Each character in the array occupies one byte
memory and the last character is always '\0'.
C
provides a shortcut method initialising strings.
Example:
char
name[] = "VRB";
Note
that in this declarations '\0' is not necessary. 'C' insert '\0' automatically
at the end of the string.
Example:
char
name[] = "COMPUTER";
The
memory representation of above initialization is shown here.
Example 1: Program to
print array of characters.
/* Program using array of characters */
#include <stdio.h>
#include <conio.h>
main()
{
/* Local definitions
*/
char
name[]="VRB";
int i=0;
/* Statements */
while(i<=2)
{
printf("%c",
name[i]);
i++;
} /* while */
} /* main */
OUTPUT
VRB
EXPLANATION:
In this program, we have initialised a character array, and print the string
character by character using the while loop.
Example 2: Program to
print the character string from the array.
/* Program using array of characters */
#include <stdio.h>
main()
{
/* Local definitions
*/
char
name[]="VRB";
printf("%s", name);
}
#include <stdio.h>
main ()
{
/* Local definitions
*/
char name[] =
"VRB";
int i=0;
/* Statements */
while(name[i]!=
'\0')
{
printf("%c",
name[i]);
i++;
} /* whiles */
} /* main */
OUTPUT
LAK
EXPLANATION:
Here every character in an array is checked whether it is a null character are
not. If it is a null character then the control is transferred to the outside
of the loop, that is the end of the program. Otherwise it continues with
printing.
