Perhaps you should read the manual, expecially the examples: ChartNext - Chart Operations - MQL5 Reference - Reference on algorithmic/automated trading language for MetaTrader 5

You need to create two arrays: one will contain the names of all symbols, the second - the names of the charts.

Then it remains to go through the arrays and perform the comparison.

Example:

   long currChart,prevChart=ChartFirst();
   int i=0,limit=100;
   while(i<limit)                      // we have certainly not more than 100 open charts
     {
      currChart=ChartNext(prevChart);  // get the new chart ID by using the previous chart ID
      if(currChart<0)
         break;                        // have reached the end of the chart list
      string chart_symbol=ChartSymbol(currChart);
      //---
      int size_charts=ArraySize(charts);
      ArrayResize(charts,size_charts+1,9);
      charts[size_charts]=chart_symbol;
      //---
      Print(i,ChartSymbol(currChart)," ID =",currChart);
      prevChart=currChart;             // let's save the current chart ID for the ChartNext()
      i++;                             // do not forget to increase the counter
     }
//---
   int total=SymbolsTotal(true);
   for(int j=0; j<total; j++)
     {
      string symbol_name=SymbolName(j,true);
      int size_symbols=ArraySize(symbols);
      ArrayResize(symbols,size_symbols+1,9);
      symbols[size_symbols]=symbol_name;
     }
//---
   int size_charts=ArraySize(charts);
   int size_symbols=ArraySize(symbols);
   for(int j=0; j<size_charts; j++)

        {

You just have to insert the counter in this code
