Nested Loops: While Loop + For Loop

in Programming Questions • 1 year ago

So I recently started coding as part of my course curriculum, I lack quite a lot of experience with programs as a result am unsure about how to handle my current problem:

I'm working on a short Processing exercise that uses While Loops and For Loops with the intention to purposefully delay a calculation program, at least that's the half of it. The aim so far is to create a For Loop that runs a sqrt calculation a specified amount of times, in this instance a billion times (100,000,000). With the addition of a While Loop using a print function as part of the statement to print out a series of full stops. The final aim is to include the calculation loop INSIDE the forever while loop to delay the amount of times a full stop is printed. The end result should see a full stop being printed every half a second. Just to make sure I'm explaining myself clearly here are the actual instructions given:

float c = sqrt(257);
boolean always_true = true;
//commented lines - print functions marking start and end
//println("Starting calculations");
//My attempt at nesting the for loop within the while loop, unsure as to how to actually do this with the desired effect :/
while(always_true){
for(c = 0; c < 1000; c++){
print(".");
}
}
//println("Finished Calculation");

N.B. I realise this is really mediocre but I really want to get this complete and help myself understand this. Desperately want to improve my coding abilities.

Thanks a lot you've been a huge help, I was starting to worry that I wouldn't understand this. Is it safe to assume then that my issue was with the placement of my float variable, and the number of repetitions I was giving my test condition for my for loop when nested in my while loop? For the latter I was crashing the program inputting wrong code and foolishly resulted to reduce the number or repetitions for my test condition in hope to test my code better.
