红宝石 |字符串连接方法

concat是 Ruby 中的 String 类方法，用于连接两个 String 对象。如果给定对象是整数，则将其视为代码点并在连接之前转换为字符。

Syntax:String_Object.concat(String_Object)

Parameters: This method can take the string object and normal string as the parameters. If it will take integer then this method will convert them into the character.

Returns: This method returns the concatenated string as a result.

示例 1：

# Ruby program for concat method
   
# taking a string object
str = "Geeks"
   
# using the method
str.concat("ForGeeks")
   
# displaying the result
puts str

输出：

GeeksForGeeks

示例 2：

# Ruby program for concat method
   
# taking a string object
str = "Geeks"
   
# using the method
# but taking integer also inside the method
# it will convert it to character
str.concat("ForGeeks", 33)
   
# displaying the result
puts str

输出：

GeeksForGeeks!
