在 Julia 中获取字符串的长度 – length() 方法

length()是 julia 中的内置函数，用于返回指定字符串的长度以及所需的开始和结束位置。

Syntax:
length(S::AbstractString)
or
length(S::AbstractString, i::Integer, j::Integer)

Parameters:

• S::AbstractString: Specified string
• i::Integer: Inclusive starting position.
• i::Integer: Inclusive ending position.

Returns: It returns the length of the specified string with desired starting and end position.

示例 1：

# Julia program to illustrate 
# the use of String length() method
  
# Finding the length of the string
# "Geeks"
println(length("Geeks"))
  
# Finding the length of the string
# "Geeks" from 2nd to 4th position
println(length("Geeks", 2, 4))
  
# Finding the length of the string
# "Geeks" from 2nd to 5th position
println(length("Geeks", 2, 5))
  
# Finding the length of the string
# "GeeksforGeeks" 
println(length("GeeksforGeeks"))
  
# Finding the length of the string
# "GeeksforGeeks" from 2nd to 2nd position
println(length("GeeksforGeeks", 2, 2))
  
# Finding the length of the string
# "GeeksforGeeks" from 4th to 10th position
println(length("GeeksforGeeks", 4, 10))

输出：
示例 2：

# Julia program to illustrate 
# the use of String length() method
   
# Finding the length of the string
# "12345"
println(length("12345"))
   
# Finding the length of the string
# "12345" from 2nd to 4th position
println(length("12345", 2, 4))
   
# Finding the length of the string
# "2468" from 1st to 3rd position
println(length("2468", 2, 3))

输出：
