Zero at end of pointer!

[FzzPoofy]

Hi,

I am having a problem with a pointer.

My pointer pn_eles[nTotNodes][nNode] is properly initialized filled with integer values, so that when I run this fragment:

	for (int iii=0; iii<nEles; iii++)
	{
		inEl >> pn_elNum[iii];
		
		for (int jjj=0; jjj<nNode; jjj++)
		{
			inEl >> pn_eles[iii][jjj];
			cout << pn_eles[iii][jjj] << "\t";
		}
		cout << endl;
	}

I get the following output:

1 2 5 4
2 3 6 5
4 5 8 7
5 6 9 8
7 8 11 10
8 9 12 11

But when I run this fragment:

for (int elcount=0; elcount<nEles; elcount++)
{
	cout << "elcount = " << elcount << endl;
	for (int iii=0; iii<nDim; iii++)
	{
		for (int jjj=0; jjj<nDim; jjj++)
		{
			aj[iii][jjj]=0;
			
			for (int kkk=0; kkk<nShape; kkk++)
			{
				aj[iii][jjj]+=NN_deriv[kkk][iii]*pd_nodes[pn_eles[elcount][kkk]][jjj];
			} //endfor
			
			cout << aj[iii][jjj] << "\t";
		} // endfor
		cout << endl;
	} //endfor
	cout << "\n \n";
} //endfor	 

I get a bus error when elcount is 5:

elcount = 5
Bus error

Through print statements, I discovered that the error is caused by pn_eles[5][3], which should be 11, is giving me:

11
0

How do I get rid of this zero at the end of my pointer array?


I'm not sure if I explained this well, please let me know if I need to clarify.

Thanks!

I don't understand. ¿how is giving you two values?
You said that the array was pn_eles[nTotNodes][nNode],
however you are trying to access till pn_eles[nTotNodes-1][nShape-1] ¿Is that a valid range?

I figured it out! There was a problem with something completely different that was causing the bus error.
