Initialize a string in C to empty string

In addition to Will Dean's version, the following are common for whole buffer initialization:

char s[10] = {'\0'};

char s[10];
memset(s, '\0', sizeof(s));

char s[10];
strncpy(s, "", sizeof(s));

You want to set the first character of the string to zero, like this:

char myString[10];
myString[0] = '\0';

(Or myString[0] = 0;)

Or, actually, on initialisation, you can do:

char myString[10] = "";

But that's not a general way to set a string to zero length once it's been defined.
