remove minus (-) - Unknown123 - 01.10.2011

pawn Код:

main()
{
    printf("result: %s", NoMinus("some-string-with-minus"));
}

stock NoMinus(string[])
{
    for(new i; i < strlen(string); i++)
    {
        if(string[i] == '-')
        {
            strdel(string, i, i+1);
        }
    }
    return string;
}

this return >>Script[gamemodes/gamemode.amx]: Run time error 5: "Invalid memory access"<<
but it should return >>result: somestringwithminus<<

pawn Код:

printf("result: %s, NoMinus("some-string-with-minus"));

This wouldn't compile.

Set it to the length of the max length of used strings.
for example, if you're using it only for "some-string-with-minus", you can set 1024 to 22. I set it to 1024, to avoid problems. If your strings will exceed 1024 characters change it to more.

There's no need for such a big function. I think you could try something like this:

pawn Код:

while((i = strfind(string, "-", false)) != -1) strdel(string, i, i+1);
