Your first program
A program is a list of instructions that the computer follows from top to bottom, and print is the instruction that shows a line of text.
A program is a list of instructions. The computer reads them from the top down and does one after the other, exactly as written.
The instruction print shows a line of text. The text goes between double quotes, so the computer knows where it
starts and where it ends.
The lines that start with // are comments: notes for people, which the computer skips. In these lessons, a comment
that says prints shows what the program prints. Try it: change the text, then run the program again.
print "Hello!"
print "I am learning to program."
// prints Hello!
// prints I am learning to program.Exercise#
Change the program so it prints two lines: first Hello, Ada!, then Nice to meet you.
print "Hello, World!"Hello, Ada!
Nice to meet you.Run it on your computer: torb run your-first-program.trb
Hint
Change the text between the quotes, then add a second line that starts with print.
Solution
print "Hello, Ada!"
print "Nice to meet you."
// prints Hello, Ada!
// prints Nice to meet you.Recap#
A program runs from top to bottom, one line after the other, and print "..." shows a line of text.
