A code that has two loops i and j

Using Arduino Programming Questions
#1

Hi,

can someone explain to me what this for loop does in the simplest way?

Note: loops are nested

for (i = 0; i < 1024; i++) {

for (j = 1; j < 1000; j++) { }

Thank you very much.

Since you didn't post a complete sketch, it's kind of hard to tell from the context if the two loops are nested or separate. Start with this: for - Arduino Reference

It's called nested loops. It is used to access mutil-dimensions data

If { } is true, it does nothing.
If you’re lucky, the compiler will see this, and simply optimise it away completely.
