// This program prints out a 2D array
// Remember that a 2D array is initialised with size:
// array[row][col] - this means that col is the inner loop, whilst row
// are the outer loop

// Problem: Print out a 2D array of numbers. Declare the 2D array and initialise
// it with numbers 
// 1. Declare a 2D array
// 2. Initialise the array with random values
// 3. Print out the array as a grid (i.e. a 2D array)
