Now inside the while infinite loop there is for and everytime inside for "i" iteration starts over from "0" ideally "i" should get the incremented value and start from 2, output is: So the point is "i" value is not saved and every time loop starts from 0, So how can i make "i" to start from the last incremented value before entering to for loop.
