+1. Using the var keyword, declare an array called cities with 2 elements of
+type string. Don't initialize the array.
+
+Print out the cities array and notice the value of its elements.
+
+2. Declare an array called grades of type [3]float64 and initialize only
+the first 2 elements using an array literal.
+
+Print out the grades array and notice the value of its elements.
+
+3. Declare an array called taskDone using the ellipsis operator.
+The elements are of type bool. Print out taskDone.
+
+4. Iterate over the array called cities using the classical for loop syntax and the len function and print out element by element.
+
+5. Iterate over grades using the range keyword and print out element
+by element.
