The easiest approach to sub or multi parameter commands is sscanf which is a string splitter. It takes a string apart based on a given range of specifiers(such as d, i, s, etc.)

I know you're not asking for code, but let's apart this example based on your command:

pawn Код:

CMD:givemoney(playerid, params[])
{
      new giveplayerid, cash; // we need to define the inputs using sscanf
      if(sscanf(params, "ud", giveplayerid, cash)) return SendClientMessage(playerid, -1, "USAGE: /givemoney [playerid] [cash]");
     
      GivePlayerCash(giveplayerid, cash);
      return 1;
}

Basically the "ud" are the specifiers.
"u" - the playerID / partofname
"d" - an integer value

sscanf returns 1 if the string didn't contain the inputs, or was formatted incorrectly according to the specifiers. 0 is returned when it is able to split the strings.
