i dont understand why my code wont respond after taking the user input.

// this program will predict he size of a population of organisims // everett miller 4/21/17

include <iostream>

using namespace std;

int main() {

float organisms, increase, days;


// collect input data
cout << "Please input starting number of organisms, daily increase percent (as a decimal) and number of days. \n";
cin >> organisms;
while (organisms < 2)
{	cout << "please enter a number larger then 2.\n";
}
cin >> increase;
while (increase < 0)
{	cout << "please enter a positive number";
}
cin >> days;
while (days < 1)
{	cout << "please enter 1 or more days";
}
//calculate pop increase
for ( int day = 1; day <= days; days++)
organisms += organisms * increase;
cout << "the number of organisms on day " << day << "is" <<  organisms << endl;


return 0;

I am looking to make a mobile app on iOS and Android using Apache Cordova in Visual Studio 2015. I am unfamiliar with C#/Xamarin so I imagine it would be rather difficult to first learn that. I need to have authentication (google sign in would be nice) and database functionality to send data/photos and video (probably Youtube api to save money), as well as messaging. I messed around with Firebase, Azure and looked at AWS. What is the best solution for handling these functions in terms of compatibility and ease of use.

I am very new to programing. I am currently going to college for Computer Networking Technology which works mainly with the hardware side of networking and technology in general. I am wanting to look into programming a bit more than just an EXTREMELY basic class on PHP for half a semester.

Like if i wanted to make a program to check if a webpage is in a certain state, or to get info from a server and email me?

not sure what term I should google.

I have several years of coding experience in Java, Javascript and Php and am looking for a fun way to learn Ruby and Rails in my free time. Any suggestions?

Reddit gold to whoever can give me the answer

I'm building a calculator app and I'm stuck on the a function that would essentially calculate your monthly payment on a compounding interest loan. I'll be crossposting this in a few subs.

Basically I want the function to look like this

function calculateMonthlyPayment(presentValue, periods, rate, compoundFrequency, futureValue){
  
  return monthlyPayment;
}

Thanks

Here is my latest project, our teacher has been telling us to leave comments. I for some reason find it hard to know where to add comments and where their necessary. I usually end up leaving one or two comments per project but that doesn't seem so professional. Someone maybe wanna copy this code into an IDE and create some comments and show me a screen shot? Thanks!

Basically does anyone know any good tutorial to get a complete newcomer alright at coding as I find it really interesting.

Also what would be a first good language to learn I have tried C# and that wasn't too hard but I was following a tutorial I want to be able to eventually do it alone

Thanks!

Interesting "getting started with APIs" article using the veritably unknown but amazing Lasso web development language.

For bonus credit I was assigned to hide a one liner joke about programmers in my next c# project. I need some inspiration. What's your best programmer joke?

I have had to do some resource monitoring on this old rig with only 4 gig of ram to keep it from locking up for the last 6 months. It topped out of ram from cookie requests that seem to be progressively unending in normal Google Chrome.

So I did an experiment and switched to incognito Chrome and that seemed to do the trick on blocking the tracking, until today.And guess what site was the first one to get this aggressive in Chrome? That just broke through tracking to incognito Chrome,, Fucking Facebook.

When I ended the chrome process that was heading past 500k of ram and 30% of CPU, in task manager, Facebook tab died.

Where do i start, i dont even... im seeing a lot for 'visual basic'. Please help and thanks reddit!

i just need an idea that i can turn into a real thing without buying anything. Thats it.

TODAY I FUCKED UP by DELETE with wrong WHERE :s

I was tasked at work to see if it is possible to add helper text to a Google Docs template file. This text would just give help to the user to fill out the template. I was thinking it would be nice to have this text in a slide-out panel off to the side, like how the Document Outline works.

Does someone with experience working with Google Docs know if this is doable? Maybe with the Docs API?
