That's much nicer. It doesn't even require you to place the '\0' at the end, either. So what was that? That's much nicer. It doesn't even require you to place the '\0' at the end, either. So what was that?
### Null Termination ### Null Termination
Strings in C are null terminated, meaning that they end with the null character. This way, the compiler (and your and everyone else's) code will know where the string ends: once the character is null, the string is over. Strings in C are null terminated, meaning that they end with the null character. This way, the compiler will know where a string ends: at the null character.
Of course, there is no 'null' button on your keyboard, but you still need to type it out somehow. That's what \0 does. Whenever the C compiler sees \0, it will insert a null character. It's just like how \n prints a newline. Of course, there is no 'null' button on your keyboard, but you still need to type it out somehow. That's what \0 does.

### Printing Strings ### Printing Strings
Another thing C makes easier for us is the printing of strings. Rather than forcing you to print out every character in the array, you can just use the %s format specifier, and treat the string like you would any `int` or `double` value. Here's an example of the hello, world program from the very beginning, made slightly more complicated with strings: Another thing C makes easier for us is the printing of strings.
