To define a two-dimensional array, _________ size declarators are required.

Short Answer

Expert verified
Answer: Two size declarators are required to define a two-dimensional array, one for the number of rows and one for the number of columns.

Step by step solution

01

Understand Two-Dimensional Arrays

A two-dimensional array is an array of arrays, which can be thought of as a table with rows and columns. It consists of multiple one-dimensional arrays that share the same indexing system. In programming languages like C++ and Java, two-dimensional arrays are defined using a matrix notation with two indices: one for the rows and one for the columns.
02

Identify the Size Declarators for a Two-Dimensional Array

To define a two-dimensional array, we need to specify the size of both its dimensions: the number of rows and the number of columns. These dimensions are the size declarators for a two-dimensional array. We use two size declarators to allocate memory for the array and to access its elements.
03

Conclusion

In summary, to define a two-dimensional array, two size declarators are required. These declarators specify the number of rows and the number of columns, allowing for proper memory allocation and element access within the array.
