C/C++ :: Getting Started With Contour Plots
Oct 23, 2014I'm new to C++ programming and only have a little java experience but I'm trying to learn some C++. I want to create a simple contour plot from scratch, and I see that there are many programs online, but what I haven't found are the basic components to a contour plot! I know that I have to make some kind of grid, I need to identify/set levels, etc.

C Sharp :: Graphic Pen 1 Sided Width?
Apr 28, 2012I am drawing two circle (inner circle and outer circle) using DrawElipse method. I have created two pen object named OuterPen and InnerPen and creating Outer Circle using OuterPen and Inner Circle using InnerPen. Problem that I am facing is that when I increase the size of outer pen lets say 10px then it overlaps the inner circle and inner circle is hide. How can I increase the size of OuterPen outwards and not inwards so that it don't overlap the inner circle?

Jan 21, 2013tell me where the errors in the below code are?
Extra info:
getrowsize() gives the size of a row in bytes (see VGA CRTC register).
getVRAMMemAddrSize() gives the size of a pixel in memory (1=byte,2=word,4=dword)
set/getBitPlaneBit(startaddr,plane,offset,bit[,on when writing]) sets/gets a bit on a specific bit plane offset (start addr is the start address register from VGA,
plane is the plane to read/write,
offset is the offset within the plane,
bit is the bit to read/write (0-7),
[on(when writing) is the value of the bit)]

View 2 Replies View RelatedC++ :: Shared Library Vs Static Library?
Jan 17, 2014I've been reading about libraries; How to make them, how to use them, the different types of libraries, etc..
When using a shared library, does the program require that library to be installed on the computer after the program has been compiled into an .exe?
Ie.. if somebody downloaded a "Helloworld.exe" that I had compiled on my computer using a shared library (that wasn't part of a standard operating system), would they also need that shared library on their computer for the program to run without errors?
and for Static Libraries, when I compile a program using a static library, does it include in the final binary only the functions of the library that are actually used, or does the compiler add in the entire library?

On a million digits of Pi I've debugged the program and seem to have about a megabyte too much of memory at the end of the program (I start with around 250k before any allocation begins and end at around 1200).
int main(int argc, char *argv[]) {

May 9, 2013I have been trying to find a way around the following:
I am using a library functor to solve the root of a non linear equation. It passes two doubles and the name of a function that contains the equation to be solved.
Its xtor and operator are
RootFind(double tL,double tR,double (*fn)(double t));
void operator()(double tL,doubleR,double (*fn)(double t));
I want to be able to send another variable to function fn; I don't know what the value of the variable will be ahead of time.
How do I get the library functor to take an extra variable in the function passed?

C++ :: UDP Socket Library On Linux
Jan 29, 2014I'm attempting to write a little UDP socket library in c++ on linux so a user can just create a new instance of a UDPSocket class, specify destination ip and port, and just connect. Then the user should be able to call send() or receive() in any order they want.. and here I encounter a little problem..
Most of the tutorials for udp socket sending out there include a bind() call when you create your "server" that is supposed to receive data, but the code that send data does not need one. Because I also want my library to support unicast/broadcast/multicast, I have read that I need to set the socket option SO_REUSEADDR on my sockets (since multiple sockets will need to be connected to same destination IP/port for broadcast/multicast)
My question is.. do I need to create 2 socket handles per "UDPSocke in order to make this work? One for sending and one for receiving data? In my code when I try to work with only 1 socket, it is only able to receive stuff from itself on unicast.. Or should I just remove the SO_REUSEADDR when in unicast mode, then try to bind with both sockets, accept that the bind will only work on the 1st socket, and take it from there?
C :: Creating A Library Function
Jan 27, 2015I want to create a C library function that i can directly call in my code from any .c file having main program.following are codes...code of library function "foo.c"
Code:
#include "foo.h"
int foo(int x) /* Function definition */ {
return x + 5;
} header file "foo.h"
Code:
#ifndef FOO_H_ /* Include guard */
#define FOO_H_
int foo(int x); /* An example function declaration */
}
[code]....
to use this i have to compile the file in below manner...
Code: gcc -o my_app main.c foo.c
My concern here is that i want to compile the main.c and use function without compiling foo.c with i.e.
Code: gcc -o my_app main.c
any user of this function should only compile his program and should be able to use the function, the foo.c file should remain hidden from him
my system is Linux 2.6.18-308.4.1.el5 #1 SMP Wed Mar 28 01:54:56 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux
C :: Static Library Linking
Oct 7, 2014I am trying to refresh my memory here as I did some studies many years ago but the results elude me.Also todays c/c++ compilers may have better optimizations.Say I have a static library that includes three obj modules.Each of these object modules has a number of functions. These functions do not reference any other functions within the obj module.My main app links this library but only references one function from each of the object modules.
Question: Are the complete contents of each module linked into my main app or are todays linkers smart enough to just link the functions used?

Mar 8, 2013I am in try to use PlPlot library (for plotting) in C with code::blocks IDE (ver 10.05) on windows-7 plateform. I downloaded "plplot-5.9.9.tar" and unzipped it. In documentation it is not very clear to me (I am not expert in using third party lib.), how this library can be used with code::blocks i.e. where I have to save the lib, what should be added in compiler and debugger settings etc. It also seems from document that "makefile" (linux type!!) is necessary for Windows also? I am also unaware of MSYS makefile generator (given on Wiki page) on windows?

C++ :: List Library - How To Traverse Through A And B
Aug 22, 2013I'm trying to make a list that contains other lists. I want to use the <list> library /not my own implementation/. Here is what I do:
list<list<int>> Lists; //I create the main list
list<int> A, B; //Then I create the other lists
//After I fill them with data I add them to the main list
Lists.push_back(A);
Lists.push_back(B);
The problem comes when I try to go through A and B. I make an iterator of the main list:
list<list<int>> Iter = Lists.begin();
Then I need to make an iterator to traverse through A and B. But I can't make it. I do this:
list<int> Iter2 = Iter.begin() //But the compiler says it is not possible
How can I traverse through A and B?
C++ :: How To Use Regex Library To Use It In CLI Game
Jan 18, 2015I want to use C++ regex library, to use it in my lil' CLI game. The aim is to create the template(not C++ template :)) for command(like "go north"). Then, if player writes anything that contains "go", and "north" appearing after that(examples: "go north" "please go north" "Let's go north!" "Princess, I insist that we go to the north") would all be interpreted as simple "go north". I have used a bit of regex in Linux system, but not this ECMAScript regex that C++ uses.I've checked in some online regex tester, that if I write: ".*go.*north.*" then anything I want will be matched; however, I'd like these to be specifically separated by space(the rule is: between north and go there must be at least one character: a space, so that gornorth won't be interpreted as command.).
Bonus points: if it's possible to do that without some kind of black magic, I'd like to achieve following goals:
1)Before go, there can be any amount of characters, but if there is 1 or more characters, the character just before go must be space.
2)In between go and north, there must be at least one character, space. If there are more, then characters right after go and just before north have to be spaces.
