Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with BASIC V2.0 for the C64 by Commodore Business Machi.

What does the following BASIC V2.0 code do?
10 PRINT "HELLO, WORLD!"
20 END
This code prints the string 'HELLO, WORLD!' to the console and then ends the program.
What will be the output of the following BASIC V2.0 code?
10 FOR I = 1 TO 5
20 PRINT I
30 NEXT I
40 END
This code will print the numbers 1 through 5, each on a new line, and then end the program.
What does the following BASIC V2.0 code do?
10 DIM A(5)
20 FOR I = 1 TO 5
30 A(I) = I * I
40 NEXT I
50 END
This code initializes an array A with 5 elements, then fills each element with the square of its index, and then ends the program.
What does the following BASIC V2.0 code do?
