my a book or website where I can make a transition from console programming to GUI programming. I'm totally confused about this. I know how to program in console and can make a whole program based on console. I also know the OPP programming, but it's clear that nobody uses console programming anymore.
I'm trying to implement a simple template array class, but when i came into the operator< i actually have to use a template :
my code is something like :
template<typename _Type, std::size_t _Size> class array { public :
[Code] ......
but i am having an error of shadows template param 'class _Type' is it w/ the name conflict between the array template parameter and the function template parameter ?

I have a generic template class with another template in one of its types. Now I want to specialize one of its methods for a particular (template) class, which leads to a compile error, however.
GCC ends with: :35:27: error: type/value mismatch at argument 2 in template parameter list for ‘template<class Type, template<class> class O> class Foo’ :35:27: error: expected a class template, got ‘Obj2<Type>’
What is wrong with the specialization? Can it even be achieved and how (if so)?
how I want the code to look. Only problem is it doesn't work (Line 11). I have some experience with templates but I'm not a pro.
Basically I want the "Channels<3>" to be a type that I can use to specify a Cable with similar to vector<float/int> it would be Cable<Channels<2 or 3>>.
What have I messed up with the syntax?
#include <iostream> #include <vector> using namespace std;
where 'g()' returns an object of the element type. However, the compiler is claiming, no matter how I write a call to the overload, the original template is selected and/or the overload is invalid, depending on the various ways I attempt to write said overload.
I have tried several variants on this code to no avail. Outer is in a header, along with the extern template statements, and the specializations after main are in their own cpp file. Main is in a different cpp file.
What do have to do to make this work? I cannot bring the definitions of f() into the header, and they will be different for different template parameters. Ideally, I want Test to remain a private member of Outer, though this can change if it's the only option.
And then have another template function declaration for all the attractor functions where I pass the same template value as in the first one.
As you can see, I'm calling another functions inside called attractors(_tmp). I know that one way around it could be to get rid of that function and just do all the logic inside of each if statement. Is there any way to pass the same template function parameter within a template function parameter?
I am trying to test my client-server socket program wherein the client connects to the server,client sends a message, server receives it and echo back to the client.So far, in the program server receives the message from the client, prints it BUT when it tries to send the message back to the client it shows an error.
sendto(): Invalid argument.I am new to socket programming.
Code:
//Server #include<stdio.h> //printf #include<string.h> //memset #include<stdlib.h> //exit(0) #include<netinet/in.h> #include<sys/socket.h> #define BUFLEN 512 //Max length of buffer #define PORT 10003 //The port on which to listen for incoming data }
/** This class build the singleton design pattern. Here you have full control over construction and deconstruction of the object. */ template<class T> class Singleton
[Code]....
I am getting error at the assertion points when i call to the class as follows:
I try to ON and OFF the LED's via parallel port. I connect the cathode of LED's with pin number 18 that is ground and anode of each LED is connected through a 1K resistor to pin 2 to 8. I write the following programe
I'm supposed to make a program that can tell which date, out of any number of dates entered by the user, is the earliest date. However, this is based off another program that I did not do in the last chapter. Since it's a pretty simple program to use as the base for the more "generalized" one, I decided to make the more basic one that can only take two dates, first. If it was just one integer, I could just use date1 for the first date and date2 for the second date, but each date uses 6-8 separate numbers.
how do I tell it something like, "if(date1 < date2)", with date1 and date2 including their month, day, and year. I could do a separate integer name/tag (I forgot what they're called) for each number, but that sounds like doing a lot more adding and subtracting, and like it could easily get messy.Should I, or can I, add all the numbers under the "date" together to see which date has the "lowest number" or "earliest date", or should I somehow handle each number, that is month, day, and year, separately?Here's the code so far:
Code:
include <stdio.h>int main(void) { int date1, date2; printf("Enter first date (mm/dd/yy): "); scanf("%d/%d/%d", &date1); printf("Enter second date (mm/dd/yy): }
I am trying to send a packet across a client/server communication. I am getting a seg fault (while running the program(It compiles fine)) when I try to read the neighbor file, You should be able to see this below the comment /***** Read neighbor file***/ :
I know this question must have been asked before, but the problem that I am facing is that I am using a library PoDoFo to parse PDF files. It seems that it is only compatible with C++.
Now I want the application to be web-based. That is, the user uploads a PDF file on the server, the server parses it and the parsed content is then sent back to the user.
Is such a thing possible with C++, or maybe any good work-arounds? Or should I look at server-side scripting languages like PHP and their respective libraries?
Where are the c programming variable name rules defined? I usually use these two websites for figuring out these kind of things but I don't see it anywhere.
I am trying to read all the 9 letter words in a words list text file and print them to the screen. Here is the code I have so far, but I am currently printing nothing.
Code:
#include <stdlib.h> #include <stdio.h> #include <string.h> int main() {
I'm trying to make an alphabet soup on C programming, and I'm stuck with a problem.I need to make a function able to automatically find all the words that exist in alphabet soup.
I have attached a circuit diagram below, which has been tested. Currently you have to manually push the switch to change the brightness of the bulbs. I want to program a chip to automate this.
Over 90 days the chip will output a high signal in replace of the switch every set period of time (say once every 1.5days). I can use any chip but the smaller the better!
I would like to make a program for final project, which can let me send any file to my computer at home, and i can access any files in my computer when i am not at home.sending and getting file will be with socket programming.
i would like to reach all folders in computer, not only the folder, where client program exist. how can i access other folders at remote computer by using my program?
why an array would lose its contents when I believe it shouldn't. Below is a skeleton program just to kind of show what seems to be happening. Basically I set up the delims array with just a star. The program runs a good number of times but at some point the delims array gets lost. My guess is the stack is overflowing or something? But it "appears" all other variables are ok (although I cant be sure).
I move the char delims into the while loop. What is this "actually" doing to the original delims variable ... are we wasting memory here (bearing in mind the original delims variable is sometimes loosing the string :/)
Write a program that orders three double numbers by increasing value. The program should include a function named sort3 that takes three double * arguments (pointer to double). The function prototype is void sort3(double *x, double *y, double *z); The function should reorder the values pointed to by its arguments so that after the call sort3(&x, &y, &z); the numbers satisfy . Your program should input data and print results using the following format:
Enter three numbers: 4.7 1.4 3.2 The ordered sequence is: 1.4 3.2 4.7
And here is my program: C code - 32 lines - codepad
I am getting a lot of errors when I run it through GCC. I can only use pointers.
#include <iostream> #include <stdlib.h> #include <time.h> using namespace std;
/* function main begins program execution */ int main() {
[Code] .....
I have gotten the conditions to execute properly but will end the program after doing a case instead of asking to play again and loop. Also how would i output the number of wins and losses?
