how to iterate a map with its key/value with a count just like "i ++" in the "for" statement

I am using go language and I want to iterate a map with its keys and values all over a map,
at the same time, I also want to count the number of items in the map

I tried this:

  for i := 0; k,v := range map; i++ { }

I just want to know if for ... range statement can work with i++ which is usual part of
for statement

As you must have discovered when you tried it, that doesn't work. You have to just spell it out:

i := 0
for k, v := range someMap {
    //...
    i++
}

The range clause of the for statement doesn't allow this. You have to write, for example:

var i int
for k, v := range myMap {
        whatever()
        i++
}

Note that if you don't mutate the map while iterating over it then

i == len(myMap)

is true afterwards.
