There are 4 'chars' per array element, which means sizeof doesn't work as I need it to. If it's 1, 2, 3 or 4 chars, it will return 1. If it's 5, 6, 7 or 8 chars, it will return 2. It only works in 4's. Is there no way to do sizeof on a char-array?

pawn Код:

public OnFilterScriptInit()
{
    new bool:charArray1[10][1 char];
    printf("sizeof: %i", sizeof(charArray1[]));
    
    new bool:charArray2[10][4 char];
    printf("sizeof: %i", sizeof(charArray2[]));
    
    new bool:charArray3[10][8 char];
    printf("sizeof: %i", sizeof(charArray3[]));
    
    new bool:charArray4[10][9 char];
    printf("sizeof: %i", sizeof(charArray4[]));
    
    new bool:charArray5[10][20 char];
    printf("sizeof: %i", sizeof(charArray5[]));
    return 1;
}

Output: 1 1 2 3 5

Sizeof is correct - it returns number of cells. Using 17 char will use 5 cells anyway.

Yeah I know. Is there a way to return the number of chars?

Let me rephrase it. When you initialise the array

pawn Код:

new bool:charArray1[10][5 char];

In fact it's same as if you'd do

pawn Код:

new bool:charArray1[10][2];

Number of chars isn't saved anywhere.

I know that.

Are char-arrays null-terminated? I'll test it out.

EDIT: Well, they aren't exactly null-terminated, but any chars you don't set are automatically \0 (null-terminator) so I can just init the array with 1 more char than I need then go from there.

It's not exactly ideal, as I can't use bool:, I have to do this:

pawn Код:

new charArray[5][5 char];
    
charArray[0]{0} = '0';
charArray[0]{1} = '1';
charArray[0]{2} = '0';
charArray[0]{3} = '1';

I can't think of another way to do this.

Thanks for the help anyway.

strlen works with packed strings. If all your values are non 0, then it will do the trick

[MP2]

That's the problem - maybe they are all 0/false.

To be honest I've been thinking the same thing. It's a lot of hassle to save a few KB (or less, I'm not sure) of memory.

If you array is shorter than 255 chars, you could sacrifice first char to hold the size of it. Of course not the handiest way
