The chr function in Ruby returns the string containing the character represented by the int’s value according to encoding.
Syntax: string.chr([encoding])
Parameter: The function takes the integer value whose encoding is to be done. It takes a non-mandatory parameter encoding if encoding is to be done according to that.
Return Value: The function returns character.
Example #1:
# Ruby Program of Integer chr function # Initializing the numbers num1 = 65
num2 = 66
num3 = 97
num4 = 245
# Prints the chr # after encoding puts num1.chr puts num2.chr puts num3.chr puts num4.chr(Encoding::UTF_8)
|
Output:
A B a õ
Example #2:
# Ruby Program of Integer chr function # Initializing the numbers num1 = 119
num2 = 68
num3 = 89
num4 = 255
# Prints the chr # after encoding puts num1.chr puts num2.chr(Encoding::UTF_8)
puts num3.chr puts num4.chr(Encoding::UTF_8)

Output:
w D Y ÿ
