使用Julia编程语言进行打印

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.

在所有编程语言中， **打印**是最重要的步骤，我们在屏幕/控制台上打印文本。 通过预定义的功能/方法进行打印。

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

在Julia语言中–我们使用print()和println()函数在屏幕上打印文本。

## print()和println()函数 **(**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).

print()和println()函数用于打印对象的字符串表示形式，它们可以用于在字符串上打印任何文本/字符串，值，变量的值。 我们还可以使用字符串连接技术来打印多个内容(就像其他编程语言一样)。

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

print()和println()之间的区别在于， print()在打印文本之后不包括换行符，而println()包括换行符。

**Example 1:**

**范例1：**

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

**Output**

**输出量**

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

**Example 2:**

**范例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**

**输出量**

Hello World!
    Hello IncludeHelp!
    Hello World!
    Hello IncludeHelp!
    10
    10.23
    -1234.56
    10
    11
    20
    20
    x: 10
    x+1: 11
    x+10: 20
    x+x: 20
