Drawing multiple TH1F arrays

ROOT
1

say I have something previously defined arrays of TH1F *h0[i] to hn[i] pointers

for (int i = 0; i < n+1; i++) {
   h0[i] = new TH1F( TString::Format("h0%d", i), "", nPos, -0.5, ((Double_t) nPos + 0.5) );   
   h1[i] = new TH1F( TString::Format("h1%d", i), "", nPos, -0.5, ((Double_t) nPos + 0.5) );   
    ...
   hn[i] = new TH1F( TString::Format("h7%d", i), TString::Format("Channel %d", chanEval[7]), nPos, -0.5 ((Double_t) nPos + 0.5) );   	
}

and at some point I want to draw, n TH1Fs in a single canvas. Instead of

Int_t w =2000; 	Int_t h = 965;
TCanvas *c0 = new TCanvas("c0","",w,h);
c0->SetWindowSize( w+(w-c0->GetWw()), h+(h-c0->GetWh()) );	
c0->Divide(n/2,2);

c0->cd(1);
gPad->Update();
h0[0]->Draw("C");
for (int i = 1; i<n; i++){
   h0[i]->SetLineColor(i+1);
   h0[i]->Draw("same c");		
}
	...
c0->cd(n);
  gPad->Update();
h1[0]->Draw("C");
for (int i = 1; i<n; i++){
   hn[i]->SetLineColor(i+1);
   hn[i]->SetLineColor(i+1);
}

how can I more elegantly write , where %d = i

for (int i=1; i<9; i++){
   c0->cd (i);
   gPad->Update();
   h(%d-1)[0]->Draw("C");	
   for (int i = 1; i<n; i++){
      h(%d - 1)[i]->SetLineColor(i+1);
      h(%d-1)[i]->Draw("same c");		
   }
}

The syntax you are using:

      h(%d-1)[i]->Draw("same c");

Is not valid C++ … obviously…
You making “some guess” from what we told you in another post…

What you are trying to do here looks like a 2D array … so do a 2D array.
You can find this in many good C++ books.
