|
|
// EXERCISE: Declare the arrays as slices
|
|
//
|
|
// 1. First run the following program as it is
|
|
//
|
|
// 2. Then change the array declarations to slice declarations
|
|
//
|
|
// 3. Observe whether anything changes or not (on the surface :)).
|

|
// EXPECTED OUTPUT
|
|
// names : []string ["Einstein" "Tesla" "Shepard"]
|
|
// distances: []int [50 40 75 30 125]
|
|
// data : []uint8 [72 69 76 76 79]
|
|
// ratios : []float64 [3.14]
|
|
// alives : []bool [true false true false]
|
|
// zero : []uint8 []
