Pointer to a string acts similar to that of a pointer to array, here the pointer variable holds the address of the first-string variable and hence the required operation is executed.
Syntax:
char ch[5]=”ABCD”;
char *ptr=ch; 
The above description depicts the pointer to a string where the first address value 1000 is stored in the pointer variable.
The next address is incremented by 1 as each character of a string holds a value of 1 memory space. This 1000 or the first address is used to access the string.
Let’s see an example how pointer is used to access an string:
#include<stdio.h>
int main()
{
char ch[10]="POINTER";
char *ptr=ch;
while(*ptr!='\0')
{
printf("%c",*ptr);
ptr++;
}
return 0;
}Here in the above program the address of the first-string variable is stored in the pointer variable as the string is initialised in it.
The pointer keeps on incrementing with 1 as each character holds a value of 1 memory space until it reaches to the end or NULL and keeps on printing the string by invoking the pointer, then the loop is terminated.
