int corchoice, k, l, i ,j;
for (i = 6; i >= 0; i--)
{
cout << endl;
for (j = 0; j < maxc; j++)
{
if (np[i][j] == -1)
cout << " ";
else
cout << setw(6) << np[i][j];
}
}
cout << endl << "Is this pyramid correct?(yes = 1/no = 2)" << endl;
cin >> corchoice;
while (corchoice != 1)
{
cout << "please enter the row of the incorrect number." << endl;
cin >> k;
cout << "please enter the column of the incorrect number." << endl;
cin >> l;
cout << "Please enter a integer for the array number: " << "[" << k << "]" << "[" << l << "]" << endl;
cin >> np[k][l];
cout << endl;
for (i = 6; i >= 0; i--)
{
cout << endl;
for (j = 0; j < maxc; j++)
{
if (np[i][j] == -1)
cout << " ";
else
cout << setw(6) << np[i][j];
}
}
cout << endl;
cout << "Is this pyramid correct?(yes = 1/no = 2)" << endl;
cin >> corchoice;
}

After printing the array again, no values are changed.
