In which data layout is row data contiguous in memory?Column majorFortran data layoutArray of StructuresStructure of Arrays

The correct answer to the question about which data layout has row data contiguous in memory is "Row major", which is the standard layout for programming languages like C and C++. In row-major order, the elements of each row of a two-dimensional array are stored in contiguous memory locations.

To provide more clarity about the terms mentioned:

1. Column Major: This data layout stores elements column by column, making the elements of each column contiguous. It is commonly used by languages like Fortran.

2. Fortran Data Layout: This refers specifically to the column-major order used in Fortran for storing multi-dimensional arrays.

3. Array of Structures (AoS): This organization typically refers to storing instances of structures in an array form, where each structure holds multiple related data points.

4. Structure of Arrays (SoA): This layout stores different properties of an object in separate arrays, which can help improve performance in certain operations, but it does not maintain row contiguity.

In conclusion, if the question is specifically about which layout keeps row data contiguous in memory, the answer is Row Major, which contiguously arranges the data corresponding to rows of a multidimensional array.
