Here’s a short practice exercise for Julia:
- Write a Julia function that takes two arguments (a and b) and returns the sum of the two arguments.
function sum_two_numbers(a, b) return a + b end println(sum_two_numbers(3, 4)) # should print 7
- Write a Julia program that uses a for loop to print the numbers 1 to 10 to the console.
for i in 1:10 println(i) end
- Write a Julia function that takes a number as an argument and returns “even” if the number is even, and “odd” if the number is odd.
function even_or_odd(number) if number % 2 == 0 return "even" else return "odd" end end println(even_or_odd(4)) # should print "even" println(even_or_odd(7)) # should print "odd"
- Write a Julia program that reads in a user’s name from the console and then prints a personalized greeting.
print("What is your name? ") name = readline() println("Hello, $name!")
- Write a Julia program that calculates the area of a rectangle, given its length and width.
function calculate_rectangle_area(length, width) return length * width end println(calculate_rectangle_area(5, 10)) # should print 50
These exercises should help you get more comfortable with Julia programming language. There are many more advanced topics to explore in Julia, such as linear algebra, machine learning, and data analysis. Keep practicing and exploring!
