My prog name is test and the problem is when i compile it gives error : 'test' is not recognized as an internal or external command,operable program or batch file.
Code:
#include <stdio.h>
#define ISDIGIT(y) ( y >= 48 && y <= 57 )
main( )

The below program is supposed to display the contents of all files listed in the command line. When I try to run the program I get the fatal error "Debug Assertion Failed" Expression: file != NULL. I've done some researching on the matter and I gather it might be because I don't have any files listed in the command line?
How to enter files in the command line! I opened the Command Window in Windows XP and tried typing in "C> argc" and "% argc" (argc being the name of the file containing the below program) without any luck.
Code:
#include <stdio.h>
#include <stdlib.h>
int main (int argc, char * argv[]) {
int ch; // int to hold EOF
int count;
FILE *fp;
for(count = 1; count <= argc; count++) // agrc loop

How can I send information and receive from external command prompt from my program??. I want to run an external command prompt, a code that's is not mine, to send information to this command prompt, then make my program hit enter at the command prompt and then receive back information from the command prompt.

If data is correct entered, the program should branch into line 69, a recognition of eof flag.
Instead, it always branch into line 71, the fail flag and i have no clue whats wrong.
I am programming an old-school dungeon crawler and thought it would be cool to get the pc's internal speaker in on the action. While Ive used the BEEP function to nice effect for generating music, how I would go about getting speech out of my internal speaker?

Code:
class foo {
public:
typedef std::vector<std::string>const_iterator iter;
iter begin () const;
iter end () const;
[Code] .....
In the future I see the need for this class to be able to control sequence (sorting) and also show a subset of the complete list based on a search parameter.
Using std::sort appear to solve the ability to sort the collection.
How can I return an iterator to the client which only iterates a sub-set of all items in the std::vector?
An example would be, I add this method to the class;
Code:
void find(const std::string& st);
So if the client performs (below) only items in std::vector that contains the character "a" should be possible to iterate.
Code:
foo f;
f.search("a");
One option would be to operate with two collection inside the foo class. One more static containing all items and the other containing the sorted and filtered items. This would lead to some copying but should work. Far from perfect.
I declared 3 private variables in header file.
I try to access one of the variable in its corresponding cpp file but I get an error message saying it's undefined. I did #include the header file. Why is this?
I've been wondering about something for a while:
Is it possible to declare a struct/class, in a cpp file, designed for local use, but with internal linkage?
The usecase is that every once in a while, I want to wrap "startXXX+endXXX" function pairs in a simple RAII struct. I just declare the struct in my cpp and use it once.
However, if I do this, (AFAIK), the compiler will generate an entry in the link table, which means I could potentially have link conflicts if I declare the same struct twice in two different cpp files.
Unless I'm mistaken, since the struct is declared in the same cpp that it is used, I wouldn't need external linkage. Is there a way to avoid it?
I am using C++ new/delete operators to allocate/deallocate the buffers. I think for each allocated buffer, there should be an additional info block stores the size and other info about the buffer. How to know more details about this info block? I need to override these two operators and find such an info block is useful to my implementation.

I need to know if I am using the correct method to choose file name. And how to set a script(double) variable to print input text or choose an on/off (0|1) input to be written to a text file.

I'd like to use the Big Integer Library [URL], but I have issues to use it. I'm using Xcode as compiler and I don't know how to include the library in my project files. When I drag all the files in the project directory and write the statement #include <BigInteger.hh> on the top of the declaration of the main function, even whiteout any other code, I get lots of build error on the .hh and .cc file.

I want to be able to make this code read those two lists from an external .txt file from my desktop for example. This will make it so I can read larger amount of words instead of having to paste them all in this script.

I want it to find those lists externally. How could this be done, if possible even?
I'm trying to remove the title bar from an external app. The reason is I don't want anyone to be able to move it.
But my code below doesn't remove the title bar. Could this be because it's not removable? I read somewhere title bars of external apps may be not removable if the app doesn't allow it.
So, I'm not sure why my code doesn't work - either it's wrong or the app doesn't permit it?
My app is a winform.
int style = GetWindowLong(app1Win, GWL_STYLE);
style = style & ~WS_BORDER;
SetWindowLong(app1Win, GWL_STYLE, style);
SetWindowPos(app1Win, HWND_TOP, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);

I'm trying to basically have a user input the amount of test they want averaged, then have the user input the test scores. Send the test scores to a function and have them ordered in ascending then send it to another function that averages it. When I wrote the function I keep getting the address back instead of the actual values.

#include <iomanip>
using namespace std;
void arrSelectSort( int* [], int);
void arrAverage(int);

I am new to C# and just want to understand if an entire Test Automation Framework can be built using only C#. I would not want any dependency on available commercial tools in the market for executing the Test Action steps. Though a few points that i see will need to be taken care of at the onset.
1. creating and maintaining Object repository in some form of file extension
2. preparing a GUI for capturing user Test Action Steps
3. retrieving the respective test objects from Object Repository and firing the respective Action commands on those objects
4. handling test data within the Automation Framework Solution folder.
I have been exploring a series of blogs and found that point # 2 and 4 are achievable. However points 1 & 3 above looks a big challenge.
my assignment is to print out the numbers from 2 to 20 stating if they are primes or not using loops and/or a function..once i execute, it throws the program into an infinite loop...

Why I take warning on this code :
Code:
#include<stdio.h>
extern int v = 0; // Declaration and definition of an external
int main(void)
[code]...
Is there any error? Why I take a warning: 'v' initialized and declared 'extern'|||=== Build finished: 0 errors, 1 warnings ===| ???
and what is the meaning of :An extern declaration that initializes a variable serves as a definition of the variable. This rule prevents multiple extern declarations from initializing a variable in different ways.
i'm iterating through the system processes an when i find a process that belongs to a text oriented application, i want to read that text inside the external app. For example, when i get the process to an instance of notepad, i want to get the text contained inside notepad. i've tried to do it using Process.MainWindowHandle pointer, but with no success. How to do it? (This is for an "nanny" app i'm writing, which need access to text in external applications so that i can detect any unappropriated words)
