Not the results I wanted

Weegee

Go Weegee!
Recently I was learning from a tutorial site and tried to replicate one of their examples. The link to it is here.

The code they used
PHP:
// rememb-o-matic
#include <iostream>
#include <new>
using namespace std;

int main ()
{
  int i,n;
  int * p;
  cout << "How many numbers would you like to type? ";
  cin >> i;
  p= new (nothrow) int[i];
  if (p == 0)
    cout << "Error: memory could not be allocated";
  else
  {
    for (n=0; n<i; n++)
    {
      cout << "Enter number: ";
      cin >> p[n];
    }
    cout << "You have entered: ";
    for (n=0; n<i; n++)
      cout << p[n] << ", ";
    delete[] p;
  }
  return 0;
}
Their code displays perfectly. I copied it over into my IDE (Visual C++ 2010) and it worked as the example intended. My replicated code:

PHP:
// Example use of dynamic memory (memory allocated during runtime)
#include <iostream>
#include <new>
using namespace std;

int main ()
{
	int i,n;
	int * p;
	cout << "How many numbers would you like to type? ";
	cin >> i;
	p= new (nothrow) int[i];
	if (p == 0)
		cout << "Error: Memory could not be allocated";
	else
	{
		for (n=0; n<i; n++)
			cout << "Enter number: " << endl;
		    cin >> p[n];
	}
	cout << "You have entered: ";
	for (n=0; n<i; n++)
	{
		cout << p[n] << ", ";
	delete[] p;
	}
	return 0;
}
This displays oddly for me. It displays all of the "Enter number" texts at once (So if i typed that I wanted to enter 2 numbers, it would display "Enter Number" twice and only gives me the option to input once). I think i copied I replicated it correctly, but I might have missed something, does anyone see or know what is wrong with my code? Let me know if you need to know something more

You need to pay attention to the curly brackets ({ and }).
  • Theirs:
    Code:
      else
      {
        for (n=0; n<i; n++)
        {
          cout << "Enter number: ";
          cin >> p[n];
        }
        cout << "You have entered: ";
        for (n=0; n<i; n++)
          cout << p[n] << ", ";
        delete[] p;
      }

    Code:
        else
        {
            for (n=0; n<i; n++)
                cout << "Enter number: " << endl;
                cin >> p[n];
        }

        {
          cout << "Enter number: ";

        }

        delete[] p;
        }

If something like for, if, else, or while is followed by { statement1; statement2; }, all of code will be inside it. However, if they're followed by statement1; statement2;, only statement1 will be inside them.

So this will print nothing:
PHP:
if (false)
{
    cout << "Hello!" << endl;
    cout << "Hello!" << endl;
}
while this will print "Hello!":
PHP:
if (false)
    cout << "Hello!" << endl;
cout << "Hello!" << endl; // This line isn't inside the if, so it's executed!
 
General chit-chat
Help Users
  • No one is chatting at the moment.
  • Varine Varine:
    Plus I'm confident it's only one of my bosses, the other owner is pretty cool. But I don't think he's the one that has as much control over executive decisions
  • Varine Varine:
    They aren't cutting my responsibilities or interjecting in my management abilities or anything, it's just stupid shit that comes up. And they don't exactly have people lining up for my job, there's not that many people applying for the positions I hire
  • Varine Varine:
    Eh, whatever. Thanks for listening guys
  • jonas jonas:
    Sure :) Let us know how it ends
  • Varine Varine:
    All of these things will end happily, they're just stressful. And I still lack many good friends that I can go to, and the ones I can are preoccupied with similar things. Thus general chit chat, cuz for some reason TH and Ghan and Tom all actively keep it up.
  • Varine Varine:
    Just gotta keep Miss Mazie up through the week until her shock wears off and she realizes that she still has family all around her, and bossman will do whatever he's going to do and I'll respond appropriately when it happens. Thank you all for the support, I do very much appreciate everyone being here for me through the years

  • vypur85 vypur85:
    Best of luck Varine!
  • vypur85 vypur85:
    I just gotten myself an offer to work in China. The pay quadruples my current one. Damn.... Not really ready to start a new life there in China.
  • The Helper The Helper:
    I have heard that they pay pretty good to English teachers in China - you would be an expat
  • jonas jonas:
    Cool, what kind of job?
  • Accname Accname:
    I would be careful with jobs in China. They can be hit and miss depending on where in China you go. Places like hong kong / Shengzen / Beijing can be neat. Other places not so much.
  • Accname Accname:
    I would recommend searching for some first person experiences for the city you got the offer in. Especially now when the political situation in China is deteriorating.
  • jonas jonas:
    Accname, long time no see
  • jonas jonas:
    What have you been up to
  • tom_mai78101 tom_mai78101:
    Hey Accname, welcome back.
  • Accname Accname:
    Not much. Working in the Renewable Energy Sector as an IT Consultant. Its okay, but I think I preferred working at the university. It was more relaxed and you met all kinds of crazy people there.
  • vypur85 vypur85:
    I gotten a teaching position for Biology in a college in Wuhan (yes, there)... I suppose it should be fine there (I hope). Many of my ex colleagues are teaching in China as well currently (none in Wuhan though)
  • vypur85 vypur85:
    And I signed the contract already. I guess there's no turning back....
  • jonas jonas:
    @Accname how many hours do you work? I heard in some sectors IT consultants rack up insane hours
  • jonas jonas:
    @vypur85 sounds nice, have fun : )
  • Accname Accname:
    I am supposed to work 40 hrs a week, but I can work more if I like and I will be paid for those hours (as long as I don't go too far, there are laws and company policies, etc)
  • Accname Accname:
    In practice its basically work as much as you like, as long as the job gets done in time.
  • jonas jonas:
    Haha, my job is like that as well... that usually means I have a few 70-80 hours weeks a year, and lots of 20 hours weeks...
  • jonas jonas:
    a few weeks ago, one of my friends basically said "jonas, I received an invitation to submit something to conference X but I'm too lazy to do it and also the conference isn't advanced enough for my high level of research*, why don't you write something? Oh by the way, the deadline is in two weeks. Enjoy!" so I got two 80 hour weeks out of that kind offer. (*of course he didn't say those parts, but it's a better story this way)
  • jonas jonas:
    now I'll have next week off to make up for overtime :p and I'll play some good old gothic 2
