What is Strings expalin with declaration type and example

In C Strings are defined as arrays of characters. For example, the following defines a string of 50 characters:

  char name[50];
C has no string handling facilities built in and so the following are all illegal:

  char firstname[50],lastname[50],fullname[100];

         firstname= "Arnold"; /* Illegal */
         lastname= "Schwarznegger"; /* Illegal */
         fullname= "Mr"+firstname
                 +lastname; /* Illegal */
However, there is a special library of string handling routines which we will come across later.
To print a string we use printf with a special %s control character:
   printf(``%s'',name);

NOTE: We just need to give the name of the string.
In order to allow variable length strings the  0 character is used to indicate the end of a string.
So we if we have a string, char NAME[50]; and we store the ``DAVE'' in it its contents will look like:
