"input array type not allowed" - error; Help Needed!

[David Binka Kumatse]

Hello everyone, I just need a little help (mql5). I declared an array as an input on the global area but got some error saying "array type is not allowed".
Code below...what would be the right way to do it?

//+------------------------------------------------------------------+
//| datetime.mq5 |
//| Fxheadmaster |
//| [e-mail] |
//+------------------------------------------------------------------+
#property copyright "Fxheadmaster"
#property link "[e-mail]"
#property version "1.00"
//
input string pairName[5] = {"EURUSD","","","",""};
//
//+------------------------------------------------------------------+
//| Expert initialization function |
//+------------------------------------------------------------------+
int OnInit()
{
//---

//---
return(INIT_SUCCEEDED);
}
//+------------------------------------------------------------------+
//| Expert deinitialization function |
//+------------------------------------------------------------------+
void OnDeinit(const int reason)
{
//---

}
//+------------------------------------------------------------------+
//| Expert tick function |
//+------------------------------------------------------------------+
void OnTick()
{

}
//+------------------------------------------------------------------+

input string pairName[5] = {"EURUSD","","","",""};

Inputs can not be arrays.

// enter the currency pairs in the input separated by comma like: EURUSD, USDJPY, USDCAD
input string pairs = ""; // Currency pairs

string pairs_csv[];
    
int OnInit()
  { 
    
    int count = StringSplit(pairs, ',', pairs_csv); // split the string and store the count of elements
    
    Print("Number of pairs inputted: ", count);
    
    for(int i = 0; i < count; i++){  
    

      Print("Pair ", i + 1, ": ", pairs_csv[i]); // Print each pair for verification
    }
    
   //Comment(

   //"pairs_csv[1] = ", pairs_csv[1], "\n",
