What is a multidimensional array ?

An array of arrays is a multidimensional array. When you want to store data in a tabular form, such as a table with rows and columns, multidimensional arrays are helpful.

An array with more than one dimension is referred to as a multi-dimensional array. It is an array of arrays and a multi-level array. The 2D array, often known as a two-dimensional array, is the most basic multi-dimensional array. Technically speaking, as you will see in the code, it is an array of arrays. A 2D array is also known as a matrix, a table with rows and columns, or a 2D array.

Declaring an array with many dimensions is comparable to declaring an array with one dimension. We must inform C that a 2D array has two dimensions.

At the first character that it cannot identify as a component of a number, the function stops reading the input string.

Before performing the operation, the compiler tries to uniformly type the operands when they are of different types. In some circumstances, you must also include type conversion instructions in your software.
