Ruby 整数时间函数与示例

Ruby 中的times函数返回从 0 到比数字本身小一的所有数字。它迭代给定的块，传入从 0 到限制的递增值。如果没有给出块，则返回一个枚举器。

Syntax: (number).times

Parameter: The function takes the integer till which the numbers are returned. It also takes an block.

Return Value: The function returns all the numbers from 0 to one less than the number itself.

示例 #1：

# Ruby program for times function 
   
# Initializing the number 
num1 = 8
   
# Prints the number from 0 to num1-1 
puts num1.times { |i| print i, " " }
    
# Initializing the number
num2 = 5
   
# Prints the number from 0 to num2-1
puts num2.times { |i| print i, " " }

输出 ：

0 1 2 3 4 5 6 7
0 1 2 3 4

示例 #2：

# Ruby program for times function 
   
# Initializing the number 
num1 = 4
   
# Prints the number from 0 to num1-1 
puts num1.times { |i| print i, " " }
   
# Initializing the number
num2 = -2
   
# Prints the number from 0 to num2
puts num2.times { |i| print i, " " }

输出：

0 1 2 3
-2

示例#3：

# Ruby program for times function 
   
# Initializing the number
num1 = 5
   
# Prints enumerator as no block is given 
puts num1.times 

输出：

#
