Problem Statement

Get two integers from the user, then create a two-dimensional array where the two dimensions have the sizes given by those numbers, and which can be accessed in the most natural way possible. Write some element of that array, and then output that element. Finally destroy the array if not done by the language itself.

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Create a two-dimensional array at runtime step by step in the Mathematica/Wolfram Language programming language

The provided Wolfram code defines a function arrayFun that generates a 2D array of size m x n initialized with zeros, and then assigns a random real number to the first element of the array. The function returns the value of the first element.

Here's a detailed explanation of the code:

  1. arrayFun[m_Integer,n_Integer]:=: This line defines the arrayFun function, which takes two integer arguments, m and n.

  2. Module[{array=ConstantArray[0,{m,n}]}, ...]: Within the function, a Module is used to create a local variable array. ConstantArray[0,{m,n}] creates a 2D array of size m x n filled with zeros.

  3. array[[1,1]]=RandomReal[];: This line assigns a random real number to the first element of the array, which has the indices (1,1). RandomReal[] generates a random real number.

  4. array[[1,1]]: Finally, the function returns the value of the first element of the array.

In summary, arrayFun generates a 2D array of size m x n filled with zeros and assigns a random real number to the first element. It then returns the value of the first element.
