The document discusses how strings in C act as pointers, with examples illustrating the usage of string variables and character traversal. It provides code snippets to demonstrate different methods to print characters of a string. Overall, it highlights the relationship between string names and their memory addresses.

2.  String itself act as a pointer
 String name is a pointer to the first character in the
string

4. char str[] ="Happy";
char *p=str;
printf("%sn",str);
printf("%sn",str);
printf("%sn", p);

5. for(i = 0; str[i]; i++)
printf("%cn",str[i]);
for(i = 0; str[i]!='0'; i++)
printf("%cn",*(str+i));

6. char *ptr; ptr=str;
for( i=0;str[i];i++)
printf("%ct",*(ptr+i));
ptr=str;
for( i=0;str[i]!='0';i++)
printf("%ct",*ptr++);
