Hi all,

Just a quick note to say I've now solved the problem outlined in my original posting. It boiled down to not putting an ampersand (&) at the beginning of variable "theMatrix" in the function header.

Need help with a segmentation fault

Hi all,

I'm teaching myself C++ and getting a segmentation fault with my latest small prog. The fault occurs within the following function, at the "std::cin" statement.

Code:

void getValues(int** theMatrix, int& theRows, int& theColumns)
{
for (int row = 0; row < theRows; ++row)
{
   // prompt for values
   std::cout << std::endl << "Enter values for row " << (row + 1) << std::endl;

   // and then use a for loop to assign values from cin
   for (int column = 0; column < theColumns; ++column)
   {
      std::cin >> theMatrix[row][column];
   }
}
}

The intention of this function is to prompt for and read integer values into a 2D array.

Could someone please explain why I'm getting this fault as everything seems OK to me.

Thanks in advance,

Stuart
