Hello,
Should there be a `" "` sign in Julia to print variables and strings? In C/C++ language, `" "` sign is not needed to print the contents of a variable.
Thank you.

Can you be a bit more precise? I am not sure why a space (if that is what you refer to with `" "`) should be necessary.
If you do
```julia
a=3
print(a)
```
it just prints (the value of) a. If you also want a new line starting after that, use `println(a)`.

Your message is quite unclear. Are you looking for `”$(var1)moretext”`? That is, you can use parentheses if there is no space after the variable to be printed (or if you need to print something more complex: inside the parentheses, you can put arbitrary code)

Hello,
Thank you so much for your reply.
Why didn’t you use `$a`? Is it because your print statement doesn’t use the `" "` sign?

who said this? where? can you provide more context. That is true when you want to interpolate a variable into a string

Well, you are mixing maybe two things. Printing and generating strings.
If you just want to print something `print(a)` would dispatch on a method that prints the value of the variable `a` but if you want to generate a string containing (the value of) a, then you have to [interpolate](https://docs.julialang.org/en/v1/manual/strings/#string-interpolation) it, and that is what the `$a` does within a string.
So you could do `s="$a"` and get a string and sure, you can also just call the print function of that string `print("$a")` afterwards (even without storing that in `s`).
That is possible but not necessary to print `a`. And there might be cases where both are different, since `"$a"` internally calls `string(a)` (and not `print(a)`).
_edit:_ So I am not sure where your quote is from, but it is not correct, you can but you do not have to.

Hello,
Thank you so much for your reply.
So, when our variable is of string type, we use `$` before the variable name.

Hm, then you misread what I wrote or at least are not precise
If you have a string like
```julia
s = "HI!"
print(s)
```
works as well just fine
But if you want to bring a variable _into_ a string – the so-called interpolation, _then_ you do a `$` upfront. That is maybe comparable, but not the same, as the `%s` fields in C/C++s `sprint`s
An example
```julia
a=1 # Int
b=0.987 # Float
c = 1//2 # Rational
s = "We have $a, $b, and $c"
```
Then the String `s` looks like `"We have 1, 0.987, and 1//2"`
So the `$` is used `$` when _constructing_ a string. Sure this might be a string in the argument of a print
