Problem $1$ Filling the array

Get the number of elements the user wants in an array. A prompt for the user input is optional.

Allocate memory for an array of the appropriate size. Using pointers to $$walk the array$,$ set the value of each element of the array to its index. In other words, element $0$ should be set to $0,$ element $1$ should be set to $1,$ and so on$.$

Use the debugger to confirm that your array elements have been set properly.

Problem $2$ Printing the array

Using pointers to $$walk the array$,$ print out the value of each element in the array.

Problem $3$ Processing the array

Using pointers to $$walk the array$,$ calculate the sum of the elements in the array and print the sum. Gauss came up with a very elegant solution that you could modify to use here, but walk the array instead!
