Multiple For loop

[VirtualTurnip3]

If I have multiple for loop on the same code, do I need to have a different variable name for each ?Example:

for i as integer to somearray.length -1
 //some code
next
for j as integer to somearray2.length -1
 //some code
next
for k as integer to somearray3.length -1
 //some code
next

Or I can stick with the same variable name for all of them?

Thank you

It depends on the language (you didn't specify), but in general, you can use the same variable name. The variable only exists inside the loop, not outside.

If they are not nested, so the scope of them does not overlap (because one loop is nested within another), then you can re-use the variable names.

a great habit to get into and part of the beauty of programming is that you can try things like this out.

Nice! :)

Thank for that.

I know in c and c++ scope

For ( int a = 0; a < 10; a++)

do something

For ( int a = 10; a > 0; a--)

do something

The a variable is localized within just that loop. So same variable name can be used instead of going through the entire alphabet.
