Final answer:
Two-dimensional arrays are composed of rows and columns, similar to the layout of a spreadsheet or a chessboard where each cell represents an intersection of a row and a column.
Step-by-step explanation:
Two-dimensional arrays can be thought of as containing rows and columns. Each row represents a new line, and each column represents a new position within that line. This structure is similar to a table in a spreadsheet, where the intersection of a row and a column gives us a cell that can hold a value.
To visualize a two-dimensional array, consider a chessboard, which has rows (1 to 8) and columns (a to h). The cell at row 1, column a (1a), can hold a piece just like an element in a two-dimensional array can hold a value.
