+// EXERCISE: Declare with bits
+//
+//  1. Declare a few variables using the following types
+//    int
+//    int8
+//    int16
+//    int32
+//    int64
+//    float32
+//    float64
+//    complex64
+//    complex128
+//    bool
+//    string
+//    rune
+//    byte
+//
+// 2. Observe their output
+//
+// 3. After you've done, check out the solution
