Code:

int *ptr=5;

Pointer can only be initialized to zero or null if it does not point to a variable of that type.

Code:

char *str="helloworld\n";
printf("string value is %s\n",*str)

The "%s" conversion specification takes a pointer argument not the actual character that *str points to. So if you want to print the entire string...

Code:

printf("string value is %s\n", str);

and if you want to print the character that *str points to...

Code:

printf("str points to %c\n", *str);
