What is string literal? Null character '\0'. What about slash zero. (\0)? How its work ? Tell me info. About that.

Answer 1

As Davide says, \0 on strings means the end of array.
For pointers, NULL is for no indicate adress of memory of pointer type (see pointers on c course), unusue. When you assign like:
int *ptr=NULL;
printf("%x\n",ptr);//outputs 0, because *ptr (the memory pointed by ptr) is NULL, (dont have any adrres).
*ptr=5;
prinf("%x\n",ptr);//outputs something like 234fab82 (an hexadimal number wich is a adrres memory where the machine store the value of 5)
int a=5;
ptr=&a;
printf("%x\n",ptr);//outputs the adrres of a, wich is type int, and store the value 5;
printf("%d\n",*ptr);//outputs the value of a, wich adrres is pointed by ptr, and her value is acceded by the * operator.

Good luck.
Sory for bad english.

Read this for string literal: https://stackoverflow.com/questions/50125126/what-is-a-literal-string-char-array-in-c

\0 is the character that tell where the string ends.

If I create the array:
char array[2];
array[0] = "a";
array[1] = "b";

And then I do:
printf("%s", array);

The output will be something like that:
abgj?hkf)&#-:dh....
Until a random \0 character is found in the memory

Answer 3

\n is what is know as an escape sequence character. And what is does is that it goes to a new line when you are writing something to the console. Just think of hitting the enter key on your computer when you type. Hope this helps.
