Comma Operator with indexing 2D arrays

Question

I have this algorithm that is pseudocode for the dijkstra algorithm for graph theory. The first thing that goes on is a basic for loop.

visitedSet[0] = true          


        

Answer 1

You have to review how to access elements of 2D array. Also, take look at what comma operator does. You have to use [] twice:

adjacencyMatrix[0][i]

The following:

adjacencyMatrix[0, i]

is equivalent to:

adjacencyMatrix[i]

Which will still leave you with 1D array. And, as the error message says:

   distanceArray[i] = adjacencyMatrix[i];
// ^^^^^^^^^^^^^^^^   ^^^^^^^^^^^^^^^^^^
//   unsigned int   array of unsigned ints

You can not possibly expect this assignment to happen.
