Iask $1$: Arrays and Structure $(20$pt$)$

In this task, we will create a structure called myArray and it will have the following members:

$A[1000]$ : an array that stores up to $1000$ integer numbers. $A$ is the $1D$ representation of a $3D$ array

shape$[3]$: an array that contains the dimensions of the $3$D array.

Subtasks:

Create a structure myArray. Must finish in Lab. $(2$pt$)$

Create a function called random that creates a structure myArray. Must finish in Lab. $(3$pt$)$

Create a function called sum that returns the sum of the matrices. Must finish in Lab.$(3$pt$)$

Create a function called print to print the $3$D array. Must finish in Lab. $(2pt)$

Create a function called multiply that returns the element$-$wise matrix multiplication between two matrices. Must finish in Lab. $(3$pt$)$

Create a function called matmul that return the matrix multiplication between two matrices. This operation is only perform to the last two dimensions of the array$(5$pt$)$

Create one or more functions to check if the operation can be performed. Do not consider broadcasting. $(2pt)$

For all the function except random and the ones used to check, the only type of argument allowed is myArray. Note: Pointers are not allowed. Built$-$in functions are not allowed.
