Code Snippets


This ruby program is an adaptation of a classic technical interview problem which displays sequences of the Foobar pattern.

def foobar_logic(n)

    c = 1

    while c <= n
        if (c % 3 == 0) && (c % 5 == 0)
            puts "Foobar"
        elsif c % 3 == 0
            puts "Foo"
        elsif c % 5 == 0
            puts "Bar"
            puts c


puts "How many digits of the pattern do they want to see?"
n = gets.chomp.to_i
puts "Result:"

def convertCelsiusToFahrenheit(celsius)
    celsius * 9/5 + 32
puts "Enter degrees in Celsius: "
celsius = gets.chomp.to_i
puts "The temperature is #{convertCelsiusToFahrenheit(celsius)} degrees Fahrenheit"

Temperature Conversion

This ruby program will prompt the user for a temperature in degrees Celsius and let the user know what the corresponding temperature is in Fahrenheit.

Ordinal Challenge

This ruby program will convert a plain number to the ordinal of the number. So for example, if the user enters 2, it will display 2nd, if the user enters 3, it will display 3rd, etc.

def convertToOrdinalNumber(number)
    if number == 11 || number == 12 || number == 13
        return "#{number}th"
        last_digit = number % 10
        if last_digit==1
            return "#{number}st"
        elsif last_digit==2
            return "#{number}nd"
        elsif last_digit==3
            return "#{number}rd"
            return "#{number}th"


puts "Enter a number"
number = gets.chomp.to_i
puts convertToOrdinalNumber(number)
