Strings and Characters

This page provides syntax for strings and characters in Julia as well as some of their associated functions. Each section includes an example to demonstrate the described syntax or function.

Characters and Strings

Char is a single character
String is a sequence of one or more characters (index values start at 1)

Some functions that can be performed on strings

Action

Function

Use typeof() function to determine type

Input:

# chars_and_strings.jl

letter = 'b'
word = "good-bye"
subword = "good"

word_length = length(word)
word_first_char = word[1]
word_subword = word[6:8]

println("Length of word: $word_length")
println("First character: $word_first_char")
println("Last three characters: $word_subword")

println("$letter is in $word: $(findfirst(isequal(letter), word))")
println("$subword is in $word: $(occursin(subword, word))")
println("chop off the last character: $(chop(word))")

Output:

Length of word: 8
First character: g
Last three characters: bye
b is in good-bye: 6
good is in good-bye: true
chop off the last character: good-by
