Last Lesson: Learn to Code...
Investigate a few computing systems, starting with BASIC then moving onto Python. Illustrate: program layout including Data Structures & Algorithms
QuiteBASIC
Approach programming first via Computational Thinking where problems are decomposed and simplified into smaller steps, an algorithm is then developed with an eye on possible supported commands, which are varied for different computer languages.
Plot Square numbers (1,4,9,16,25 …) eg 3x3
Simplification: to get a 3x3 use the (pseudo) command PLOT (X,Y) =
PLOT(1,1) PLOT(2,1)PLOT(3,1)
PLOT(1,2) PLOT(2,2)PLOT(3,2)
PLOT(1,3) PLOT(2,3)PLOT(3,3)
Algorithm Use LOOP to repeat line of blobs, for a particular Y
FOR X = 1 TO 3 PLOT (X, Y)
Then precede this loop with one for Y to duplicate vertically
FOR Y= 1 TO 3
A BASIC program thus is
10 LET N= 3
20 PRINT N*N; “ “
30 FOR Y= 1 to N
32 FOR X= 1 to N
40 PLOT X,Y
50 NEXT X
52 NEXT Y
Now inc “data structure”, so can generalise; q-BASIC only a 1D array type:
10 ARRAY A
15 LET N=6
16 FOR X = 1 to N
20 LET A[X]=X
21 NEXT X
30 FOR Y= 1 to N
32 FOR X= 1 to N
40 PLOT A[X],Y
50 NEXT X
52 NEXT Y
Also other examples in qBASIC

ADVICE SUMMARY
Learn Python - it is ideal time —
— Choose an appropriate Beginner Course
— Build a real Project
— Code for 30+ mins a day
GET an interest you can computerise — something for your CV
GOOD LUCK
