Operation for summing Array variables

Hi guys.

Please can you tell me how can I do summing for my array variable?

For example

Inserted Code
   for(int z = 0; z < Pairs; z++)
     {
        if( some conditions)
          {
              mPrData[z][0] = 1;

How I can then get summing of mPrData[z][0]?
If I will have 10 pairs and four will have my condition how I will get this number four?

THX

Hope this helps.....
Inserted Code
int Index;
   
   for (int i=0; i<NumPairs; i++)
      {
      // Store the original pair index first (Note stored in second dimension)
      ChangePips[i][1] = i;
      double ld_Point = MarketInfo(jPairs[i],MODE_POINT);
      if (ld_Point == 0) ld_Point = 1;
      // Calculate the pip & value change (assume for buy at this point)
      double ld_Pips = MT_PointsToPips(jPairs[i], iClose(jPairs[i],TradingPeriod,0) - iOpen(jPairs[i],TradingPeriod,0));
      // Store in the array (Note stored in first dimension)
      if (Direction[i] == "B")
         ChangePips[i][0] = ld_Pips;           
     
      }
     // Position 1 & 2
   Index = ChangePips[0][1];
   if (TradeOpen[Index] == 0 ) // No trade currently open for this symbol
      if (ChangePips[0][0] > MinPips ) // Minumum Pip Value reached
         OpenOneOrder(jPairs[Index],Direction[Index]);
   Index = ChangePips[1][1];
   if (TradeOpen[Index] == 0 ) // No trade currently open for this symbol
      if (ChangePips[1][0] > MinPips ) // Minumum Pip Value reached
         OpenOneOrder(jPairs[Index],Direction[Index]);

Hi guys. Please can you tell me how can I do summing for my array variable?
//-----


hey crusader...... a simple method is to use ++; .... as in cnt++; or cnts++; below..... there are other methods......h

Ok guys.
I see that there is no specific "function" for do simple summing of variable in loop. I know that ++ and thanks for info.
But I was expecting that mq4 will have something implemented for example ... Sum(mPrData[i][0]) and mq4 will know that it must do summing of all mPrData[][0] variables.
But looks to me that I must stay on ++ function

Guys I have second Q.

Down below I have attached code which is not using loop but only simple coding. But I am getting strange results. I am testing it on 1M chart and it is checking three pairs. When I open all three pair on 1M chart and attach this indi. I am getting different results!!! for example on same candle on EU and EJ chart I am getting only two "1" but on EG I get on that same candle three "1". This "1" is implemented in Line Properties to help me see if code is working correct. But looks to me that it isn't because How can I get on same candle different result with exact same indi?
Can anybody help me?
If needed I can also add here some pics examples of my 1M chart
