B4Coder writes the same program as real code. Change the flowchart in the editor and the code changes with it.

1number = float(input("Type any number "))2if number > 0:3    print(str(number) + " is positive")4elif number < 0:5    print(str(number) + " is negative")6else:7    print("That's zero: not positive, not negative")

How each block becomes code: Python · Java · C++ · C# · JavaScript
