String in C

STRING

The string in C programming language is actually a one-dimensional array of characters which is terminated by a null character '\0'. Thus a null-terminated string contains the characters that comprise the string followed by a null.

The following declaration and initialization create a string consisting of the word "Hello". To hold the null character at the end of the array, the size of the character array containing the string is one more than the number of characters in the word "Hello."

char greeting[6] = {'H', 'e', 'l', 'l', 'o', '\0'};

If you follow the rule of array initialization then you can write the above statement as follows:

 char greeting[] = "Hello";

Here is a simple program for string :

#include<stdio.h>
main()
{
unsigned char ch;
for(ch=1;ch<=254;ch++)
{
printf("%d %c ",ch,ch);
}
return 0;
}

This is a C program that show all the ASCII values
