Blocks

Check whether a random number is even or odd using the remainder. This tutorial is part of the Nairda learning path. You can build it step by step inside the app, which checks every block you place before letting you move on. The steps We add a While loop, which repeats forever. We create a number variable called number and a text one called text. Above the loop we set number to a random value from 0 to 10. Behind it we add an If with a comparison in its condition. Inside the comparison we put an operation and choose the remainder. It takes the remainder of number divided by 2. If the remainder is 0 the number is even, so we write Is even. We add a second If with its own comparison. This one also gets an operation set to the remainder. And it also divides number by 2. If it is not 0 the number is odd, so we write Is odd. On the dashboard we draw a label and name it Result: And we drag the variable text onto the label. When you finish, the app takes you straight to the next tutorial in the path. ...

Give the While loop a condition so it stops instead of repeating forever. This tutorial is part of the Nairda learning path. You can build it step by step inside the app, which checks every block you place before letting you move on. The steps We create a number variable called n. We add a While loop. We put a comparison in its condition and choose less than. The comparison says n is less than 3, so the loop ends. Inside the loop we add a Set for the variable n. We give it a sum that adds 1. The sum takes the current value of n, so it grows each turn. Behind it we wait one second, to watch it count. On the dashboard we draw a label. And we drag the variable n onto the label. When you finish, the app takes you straight to the next tutorial in the path. ...

Create a function with its own canvas and call it from the main program. This tutorial is part of the Nairda learning path. You can build it step by step inside the app, which checks every block you place before letting you move on. The steps We create a text variable called terminal. We create a function called greet, which gets its own canvas. Inside the greet canvas we write hello world into terminal. Back in the main canvas we add the greet block, which calls the function. Behind it we add a While loop, which repeats forever. On the dashboard we draw a terminal and give it the variable terminal. When you finish, the app takes you straight to the next tutorial in the path. ...
