+REP how to empty and check for an empty string var - PawnoQ - 08.02.2012

hi,

like the title says.

pawn Код:

new pNames[11][24];
            for(new q = 0; q < sizeof(pNames); q++)
            {
                pNames[q]="";
            }

Now my question is how to empty these strings and how to check if they are empty.
Can i do it like above?
And if yes then how to check for it (if it is emtpy?)

thx.

Try:

Код:

new pNames[11][24];
            for(new q = 0; q < sizeof(pNames); q++)
            {
                IsNull(pNames[q]);
            }

let me explain better:

pawn Код:

//This is my variable/array defining or whatever its called ;)
new pNames[11][24];

//Now e.g. i store a players name in one of these variables like:
GetPlayerName(playerid,pNames[0],24);

//So now i wanna check somehow if a variable is empty or if there is already a name stored in it.
//But i dont know how.

//After the check i want to emtpy all variables, so can i do it like this?:
for(new q = 0; q < sizeof(pNames); q++)
{
      pNames[q]="";
}

if(strcmp(pNames[0], "") == 0)
{
     
}

isnull definition:

pawn Код:

#define isnull(%1) \
    ((!(%1[0])) || (((%1[0]) == '\1') && (!(%1[1]))))

To explicitly empty a string:

pawn Код:

string[0] = EOS // End-Of-String
//or
string[0] = '\0'
