" " <-- String
A String can be everything. "Hello", "123", "+"
If you look in the code: The Author of this code want to print x and myArr[x]. The intention of printing : is to look it better or to separate x from myArr[x].
Play around with the code and see what happens when you remove ":" or when you insert "-". (Tap "try it yourself")

Answer 4

Int myArr[5];
For(int x=0;x<5;x++) {
MyArr[x] =42;
