First.The first code isn't tried yet. Because GTA SA got deleted from my PC. So please test it and tell me if there is a problem in it.

Code:

 if (strcmp("/announce %s", cmdtext, true, 10) == 0)
		{

	if (!IsPlayerAdmin(playerid)) return SendClientMessage(playerid, 0xFF0000AA, "You are not authorized to use this command!");

	else

	SendClientMessage(playerid, 0xFF0000FF, "Announcement posted successfully!");
	SendClientMessageToAll(0xFF0000FF, "(( Admin Announcement: %s ))")
		;

Second.This code,Has a problem it doesn't want to get complied there are 5-6 errors while compling. So can you tell me about the right format for fixing it? And please explain the solution.

Code:

	{
	if (strcmp("/sethealth (Player) %s", true, 10) == 0)
	if (!IsPlayerAdmin(playerid)) return SendClientMessage(playerid, 0xFF0000AA, "You are not authorized to use this command!");

	else
	SendClientMessage(playerid, 0xFF0000FF, " (Player) health was setted to %s .");
    SetPlayerHealth(Player, %s)
	SendClientMessage(Player, 0xFF0000FF, " (playerid) has setted your health to %s . ")
 ;

Errors:-
error 035: argument type mismatch (argument 2)
error 017: undefined symbol "Player"
error 017: undefined symbol "s"
error 029: invalid expression, assumed zero
fatal error 107: too many error messages on one line

You'll have to use sscanf to get a variable, or format to set variables in a string, you might not understand it in the start, but read some on how to use it and it'll be easy as hell.

By the way, I don't think anyone have the time to test your script, do it yourself when you've got your samp back
