Is C++ row or column-major?

In the C and C++ programming languages, arrays are stored in a row-major layout; thus, column-major accesses are not optimal and should be avoided if possible.

What is a column matrix?

A column matrix is a type of matrix that has only one column. The order of the column matrix is represented by m x 1, thus the rows will have single elements, arranged in a way that they represent a column of elements. On the other hand, unlike column matrix, a row matrix will have a single row only.
