練習一：用各種Loop方式印出1~10

//方法1：For in Loop
for indexA in 1...10{
    print(indexA)
}


//方法２：while Loop
var indexB = 1
while indexB <= 10{
    print(indexB)
    indexB += 1
}

//方法３：repeat While Loop
var indexC = 1
repeat{
    print(indexC)
    indexC = indexC + 1
}while indexC <= 10

練習二：用各種Loop方式印出Shopping List

//方法1：用for in
var shoppingListD = ["Six Eggs","Milk","Flour","Bananas"]
var indexD = 0
for indexD in shoppingListD{
    print(indexD)

}

//方法２：while Loop
var indexE = 0
var shoppingListE = ["Six Eggs","Milk","Flour","Bananas"]
shoppingListE.count
while indexE < shoppingListE.count {
    print(shoppingListE[indexE])
    indexE += 1
}

//方法２：repeat Loop
var indexF = 0
var shoppingListF = ["Six Eggs","Milk","Flour","Bananas"]
shoppingListF.count
repeat{
    print(shoppingListF[indexF])
    indexF += 1
}while indexF < shoppingListF.count
