Thread: String and NULL

>How do u store make a string with letters to null ?

Code:

word[0] = '\0';

>Also also do u detect if the string is null?

Code:

if ( word[0] == '\0' )
  ...

I was thinking of something like this

Code:

#include <string.h>
*/..../*
memcpy(string, 0, sizeof string);

But I guess your way works if you don't need to ensure everything in the array is null, I always over complicate things.

err, what if string is defined as follows

Code:

char *string="Hello World";

>err, what if string is defined as follows
Then any attempt to modify it results in undefined behavior.
