Study Notes
Multi-Dimensional Arrays in C
- A multi-dimensional array in C is best described as a matrix.
- Data in a multi-dimensional array is generally stored in row-major order. This means that the elements of the array are stored in memory in a contiguous sequence, row by row.
- To calculate the total number of elements that can be stored in a multi-dimensional array, multiply the size of each dimension.
- The size of a multi-dimensional array is calculated in bytes.
- The simplest form of a multi-dimensional array in C is a two-dimensional array, which represents a table with rows and columns.
