What is the difference between '\0' and '\n'

#1

as we have used \n condition in while loop. \n is a new line character so until we get a newline character then loop will run then why at last we are putting a[i]=’\0’; instead of using ‘\n’ as newline character we are using ‘\0’ .why???

@Abhishmu5
null character is put just for terminating the character array. because our character array size can go till 1000.
Even if you don’t do this, code will work, it just a good practice of coding.

I hope it clears you doubt, please mark this doubt as resolved if you understood it.

hi @Abhishmu5

we write while(ch!=’\n’)
to read file till the end of line

suppose input file is
asdf dfsafa #@@!#$

so our character array contains all this things
right

now when we write
cout<<str<<endl;

it will print all the stuff(asdf dfsafa #@@!#$ ) and also print some garbage after that
your can try that
why??

because cout will print string until it get ‘\0’
as soon as cout get ‘\0’ it understood that now string is completed and stop printing

but in this case we don’t put ‘\0’
so it print garbage till he get ‘\0’

so to avoid this and to get rid of that garbage we have to right
str[i]=’\0’ at the end

i hope you understood now
thanks
