Where is the last of five scores?
Short answer. Index 4.
What order does a 2D index use?
Row, then column.
Remember
| Index runs 0 to size - 1 |
| 2D: [row][column] |
Five scores. Why is the last one at index four? Indexes start at zero. So index one is the second score, sixty four. In the table, row one, column zero is six. Indexes run from zero to size minus one. Two dimensions: row, then column.
