[Solved] Accessing Nested For Loop Indexes

This will not visit all indexes of the array because array indexes begin at 0, not 1. In other words, the first element of the 2D array would be adjacencyMatrix[0][0] so you should start both of your iterations from 0.

If the array has a length of 5, the largest index would therefore be four so be careful how far you iterate.

For example, if you did:

for (int i = 1; i <= number_of_nodes; i++)
    for (int j = 1; j <= number_of_nodes; j++)
        adjacencyMatrix[i][j] = adjacency_matrix[i][j];

Then it would visit:

adjacencyMatrix[1][1]; 
adjacencyMatrix[1][2]; 
adjacencyMatrix[2][1]; 
adjacencyMatrix[2][2]; 

etc...

If you did:

for (int i = 1; i <= number_of_nodes; i++)
        adjacencyMatrix[i][i] = adjacency_matrix[i][i];

Then it would visit:

adjacencyMatrix[1][1]; 
adjacencyMatrix[2][2]; 
adjacencyMatrix[3][3]; 
adjacencyMatrix[4][4];
