Beginning Programming with Just BASIC -- Tutorial 5: Arrays

In which I discuss how to use arrays, and how to use them in conjunction with loops.

[CivilDefenseEngineer]

An array is basically a set of variables. They're just a handy way of organizing data. If you wanted to store the names of, say, everyone in a classroom, you might need 30 variables. Or just one array. Also arrays interface nicely with loops. Keep watching, you might get the gist of things.

It stands for "dimensions" and gives the maximum number of elements an array can hold. (So it knows how much memory to allocate to the program)

why the values in 2d array is not displaying in rows and columns? Thank you!

[ckildegaard]

Is JustBASIC an odd exception to the rule that arrays are indexed beginning at zero (not 1)?

for i=1 to 5
for j=1 to 5
print mat$(i, j);" ";
next j
print
next i
this is how you print in correct order coulmn and files.

Well, for one I don't see an "end if" anywhere. Also, I think it's bad practice to put a branch label inside of an if-statement (e.g. [wrong]), because if you try to enter the branch without going through the if, you're going to come to an "end if" at the end that it doesn't understand.

its a grid where you can put stuffs, each square has its own coordinates and such.

Sorry but im having problems AGAIN
Everytime I try to run any program (ex print "hello world" ) it say "Runtime Error:FileSystemAccessDenied (see error.log for more information)

Why were you expecting 16 inputs? You only changed the inner loop to 4 but the outer loop was still 5. 4x5=20. Basic maths lol

also, i wish i knew this when i wrote a programme that deal cards =="
1329 lines of code for 18 cards

[danieljay]

why does this not work??
[start]
print "Hello what is your name?"
input name$
print "hello "; name$
print "Lets start the quiz "; name$;"!"
Print "Who is the creator of Microsoft?"
input answer1$
if answer1$ = "Bill Gates" then
print "good job!"
else
[wrong]
print "Sorry thats not right! Play again?"
input wrong1$
if wrong1$ = yes then
goto[start]
else
end
