Printing in Julia programming language

Julia | printing: In this tutorial, we are going to learn how to print text/values/variable's values in Julia programming language?

In all programming languages – printing is the most importing step, where we print the text on the screen/console. Printing is done by predefined functions/methods.

In Julia language – we use the print() and println() functions to print the text on the screen.

The print() and println() functions

The print() and println() functions are used to print the string representation of an object, they can be used to print any text/string, value, variable’s value on the string. We can also use the string concatenation technique to print multiple things (like other programming languages).

The difference between print() and println() is that, print() does not include a newline after the printed text while println() includes a newline.

Example 1:

print("Hello, world!")
println("Hello, IncludeHelp")
print(10+20)
println("Julia is a programming language")

Output

Hello, world!Hello, IncludeHelp
30Julia is a programming language

Example 2:

# printing the text
println("Hello World!")
println("Hello IncludeHelp!")

# string concatenation
println("Hello", " ", "World!")
println("Hello", " ", "IncludeHelp!")

# printing values
println(10)
println(10.23)
println(-1234.56)

# printing variables
x = 10
println(x)
println(x+1)
println(x+10)
println(x+x)

x = 10
println("x: ", x)
println("x+1: ", x+1)
println("x+10: ", x+10)
println("x+x: ", x+x)

Output

Hello World!
Hello IncludeHelp!
Hello World!
Hello IncludeHelp!
