I had the mother of all facepalms today, debugging code with my boss.  I couldn't figure out why a page-to-print was producing growing margins with every page.  I looked that code over backwards and forwards, and then he hits a search one time, and I see the issue.

Code: [Select]

point.X = margin += colX_1;
                ^^^^ wut

Why the fuck does that even compile?  You can't set two variables in one statement, that's impossible.

Actually, you can. Any assignment operation returns the value of the assigned object. Using the += operator is an assignment operation, so it returns margin, which, after evaluating the right-most statement, is (margin + colX_1). It's perfectly legal.

C++ example:

Code: [Select]

int operator+ (int lhs, int rhs) {
     return (lhs + rhs);
}

int operator+= (int lhs, int rhs) {
     lhs = lhs + rhs;
     return lhs;
}

Every C-based language I've encountered returns the result of the assignment operation to allow for chained assignment.

EDIT: Ninja'd.

Does anybody know how to access the uhh.. terminal buffer of a windows terminal, directly? I want to make a simple function where i can place a character a specific spot in the terminal, based on its coordinates. I am using C++ by the way.

Hrm, random question.


I'm going to need to completely get off the support of my parents soon, and as such I'll need a better job for school/etc. I've a decent knowledge of programming, and could probably get enough training for a low-end programming job within a year. Is programming a good idea for a college job?

I don't want 40 hours of work and 40 hours of school every week or I'll go crazy, but if I could support myself on a 20 hour a week programming job (assuming one exists), that'd be great. It's something I don't hate, unlike waiting tables or something like that.

The curses library should get you what you want. It's cross-platform IIRC.

Its going to be difficult. Without contacts, experience or a degree you will have a hard time getting your foot in the door. And then you are looking for non-standard work. If you know people and are good at marketing yourself as well as programming you might be able to freelance 20 hours a week on average. But a steady 20 is going to be hard to find.

Alternatively Windows has a lot of console output functions such as WriteConsoleOutput

Is anyone here particularly talented in brainfuck? It looks interesting, but the name describes it very well.

I've spent ages with it. What do you want to know?

Ah, thought it'd be something like that.

'Twas just an idea.

It will be hard to find a job, but you might be able to find someone who will pay for helping/doing stuff for commission. For example, a classmate of mine found a job writing a frontend for a small company's database system, which payed nicely.

What's wrong with Rent-a-Coder?

The fact that you are competing against people in india who think $1.50 an hour is decent pay.

It only works if you have a pre-built set of templates and manage to snipe jobs that fit the template with minimal modification.

I'm happy, after one of my Java-based hobby projects ground to a complete halt 3 or 4 years ago now (damn, has it really been that long?) when I tried moving from a purely console-based system to a purely GUI-based system, I finally motivated myself to put some more hours into it this week... and I've made real progress! My program now works again - You can type in things and the program will do them! It's a good feeling, especially since the game wouldn't even get past the first menu before.

Of course, I've now got hours of reprograming all the old code System.out.println's  so that they work with the new GUI format, but once that's done, I can finally start actually programming in new stuff.

Oh wow, I just checked it out and it's much worse than I thought. Not programming, but I imagine it's similar there:
- one guy is looking for 500 word articles on food, paying 1$/article
- another guy is offering 40$ for 15k words story (isn't that like a thin book?)

I live in Bosnia, and there's no way in hell I'd work for so little money. I could make a better living hunting and gathering in our mine-ridden forests. Who the hell works for so little? I don't think these are competitive wages even in Somalia.

Yeah, looking around vWorker.com, the prices are all over the scale, but based on my pay rate of $110 a day (before tax) which is pretty much bottom dollar for a legitimate American programmer, I wouldn't even waste my time on most of this stuff.

.... Where do you work? I could definitely go for $110 per day. I currently make about $200 per week.

Granted, I'm not working as a programmer, but still....

I digress. I came in here with a purpose. Another probably really obvious problem with another piece of code.

Spoiler: The Code (click to show/hide)

Code: [Select]

#include<string>
#include<fstream>
#include<iostream>

using namespace std;

void sortNames(ifstream& names);

int main()
{
ifstream namesIn;

namesIn.open("Ch8_Ex9Data.txt");

if (namesIn)
sortNames(namesIn);
else
{
cout << "Please ensure the file is in the same directory as this program, and then run the program again." << endl;
namesIn.close();
system("pause");
return 0;
}
namesIn.close();
return 0;
}
void sortNames(ifstream& names)
{
int commaIndex;
string subString1;
string subString2;
string originalString;
string newString;

while(names)
{
names >> originalString;
commaIndex = originalString.find(',');
subString1 = originalString.substr(0, (commaIndex - 1));
subString2 = originalString.substr((commaIndex + 2), 100);
newString = subString2 + " " + subString1;
cout << newString << endl;
}
}

It's giving me an Out of Range "invalid string position" error. Wat do?
