Ruby 结构体 each()函数

each() 是Ruby中的一个内置方法，按现有顺序返回结构的每个值。如果没有传递块，它会返回一个枚举器。

语法：struct_name.each{|x|block }

参数：该函数接受一个单一的参数块，这是它的迭代方式。

返回值 ：它按照各自的顺序返回每个结构成员。

示例 1 :

# Ruby program for each method in struct 
    
# Include struct
Company = Struct.new(:name, :address, :zip)
  
#initialise struct
ele = Company.new("Geeksforgeeks", "India", 581)
  
# Prints the value of each member
ele.each {|x| puts(x) }

输出:

Geeksforgeeks
India
581

例2 :

# Ruby program for each method in struct 
    
# Include struct
Employee = Struct.new(:name, :address, :zip)
  
#initialise struct
ele = Employee.new("Twinkle Bajaj", "India", 12345)
  
# Prints the value of each member
ele.each {|x| puts(x) }
