how can you scan a variable and then apply it?

Hey dudes, I am trying to write a code that change the sv cheats as i wish.
i mean like, i am going to write /cheats 1 and sv_cheats will change to 1;
so i try to scan from the user this info and then apply it into the code.
what is the scanning function called? how to use it? i mean in C you just scanf("%+letter",&variable)
also, i want this to print a fitting message to the client,
if the variable = 1 to print in GREEN svcheats is *on*
if the variable = 1 to print in RED svcheats is *off*
i have 0 idea how i can scan from the user chat and apply it. any help?

upd include

PHP Code:


		
			
#include <sourcemod>

#pragma newdecls required

public void OnPluginStart() {
    RegAdminCmd("sm_cheats", cheats, ADMFLAG_CONVARS);
}

public Action cheats(int client, int args) {    
    if(args < 1) {
        ReplyToCommand(client, "[SM] Usage: sm_cheats <value>");
        return Plugin_Handled;
    }    
    
    char arg[4];
    
    GetCmdArg(1, arg, sizeof(arg));
    
    if(StrEqual(arg, "1")) {
        ServerCommand("sv_cheats 1");
        PrintToChat(client, "\x04svcheats is *on*");
    }
    else if(StrEqual(arg, "0")) {
        ServerCommand("sv_cheats 0");
        PrintToChat(client, "\x03svcheats is *off*");
    }        
    return Plugin_Handled;
}

}

thanks for the code, But i am trying to understand the logic for improve.
a few questions,
is this the actual scan commnad? GetCmdArg(1, arg, sizeof(arg));?
if so, what does the one means? i understood that args is a char array, and the sizeof(args) means the bytes (am i even right?), but what does the one means?
when will args will be lower then one? when there is none? like cheats <nothing>?
thanks!

     if(args < 1) {

    char arg[4]; //creating char with any name, "arg" for example.

Thanks!
one last question, can you go a bit deeper about the first thing you need to input?
GetCmdArg(1, arg, sizeof(arg)); this 1 means you can input only 0 and 1? or what? i am not fully get what this 1 stands for (as you may see its new for me).

Arguement number to retrieve from the command.

Re: how can you scan a variable and then apply it?

argument number to retrieve.
for example we need to make a command like sm_cvar <cvar> <value>

so need to do like this

PHP Code:


		
			
    char cvar[64], cvarValue[32], buffer[96];

    GetCmdArg(1, cvar, sizeof(cvar)); //get the first argument (cvar)
    GetCmdArg(2, cvarValue, sizeof(cvarValue)); //get the second argument (value)

    Format(buffer, sizeof(buffer), "%s %s", cvar, cvarValue); //format 2 chars to one
    
    ServerCommand(buffer); //then execute the command and value from buffer char
    return Plugin_Handled;

understood, Thanks.
sorry to bother so much, But another last question.
if i would like to use this number and do something with it?
lets say i want to make a restart command and then enter seconds for it to wait before restart.
so i did this far :

Code:

public Action rr(int client, int args)

{

 if(args < 1)

 {

   ReplyToCommand(client, "[SM] Usage: sm_rr <seconds>");

   return Plugin_Handled;

 }

 

 char args[4];

 GetCmdArg(1, arg, sizeof(args));

 ServerCommand("mp_restartgame " + args);

 return Plugin_Handled;

}

i know its wrong, but how should i use that?

    } 
    char value[32]; //also do not forget to increase the size of the array. in your code char size is 4 which is too small.

    GetCmdArg(1, value, sizeof(value));

thanks,
char array in size of 4 means that it will contain 1 number? (integer byte size is 4)? how should i measure the array size? what 32 means? ofc its not 32 chars because that will be stupid. but what is it?
