Initialize a string in C to empty string

Question

I want to initialize string in C to empty string. I tried:

string[0] = "";  

but it wrote

"warning: assignment makes integer from pointer without a cast" 

How should I do it then?

Answer 1

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

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

or

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

or

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

Answer 2

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.
