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 statements are all illegal:
char firstname[50], lastname[50],fullname[100];
firstname="Tina"; /* Illegal */
lastname="Turner"; /* Illegal */
fullname="Mrs"+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:
