println

..  println(x)

Print (using :func:`print`) ``x`` followed by a newline.

Examples

In the Julia programming language, the println function is used to print the value of an expression followed by a newline character.

1. Print a string:

   julia> println("Hello, World!")
   Hello, World!

   This example prints the string "Hello, World!" and adds a newline character at the end.

2. Print numerical values:

   julia> x = 10
   julia> y = 20
   julia> println(x + y)
   30

   Here, the sum of x and y is printed, resulting in 30.

3. Print multiple values:

   julia> a = 5
   julia> b = 2.5
   julia> c = "Julia"
   julia> println(a, " + ", b, " is ", c)
   5 + 2.5 is Julia

   In this example, the values of a, b, and c are printed along with some additional text.

Common mistake example:

julia> x = [1, 2, 3]
julia> println(x)
[1, 2, 3]

In this case, if you mistakenly pass an array to println, it will print the array as a whole instead of printing its individual elements. If you want to print the elements separately, you can use the join function or a loop to iterate over the array and print each element individually.
