How to realize the creation and initialization of two-dimensional array in C language

This article is about how C language implements the creation and initialization of two-dimensional arrays. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Creation and initialization of two-dimensional arrays 1 creation of two-dimensional arrays int arr [3] [4]; char arr [3] [5]; double arr [2] [4]

Int arr [3] [4]

Two-dimensional array storage seems to be discontinuous, but in fact it is continuous.
