Little bit confused with the output, I got this during a challenge.

Answer 1

Iterations:

i=1, j=0; i+j>4 = 1>4: false.
Prints 1*0 = 0

i=1, j=1; i+j>4 = 2>4: false.
Prints 1*1 = 1

i=1, j=2; i+j>4 = 3>4: false.
Prints 1*2 = 2

i=3, j=0; i+j>4 = 3>4: false. // note: i+=2
Prints 3*0 = 0

i=3, j=1; i+j>4 = 4>4: false.
Prints 3*1 = 3

i=3, j=2; i+j>4 = 5>4: true.
Breaks the loop

Answer 2

The best way to understand any code is to use "Step over" from the debug menu in your favourite IDE or even on notepad++.Try it out and you will understand what you didn't understand. 😎😎
