How to use Dev C++

Mar 18th, 2006

I cannot figure out how to open the results/output window in Dev c++. Also how to effectively use step over / step into . I kept breakpoints at certain points in my program but step over from then onwards does not happen by pressing ctrl+f7 and I dont know how to do it . I am using
Dev C++ 4.9.9.2 version .
Thanks ,

>I cannot figure out how to open the results/output window in Dev c++.
Assuming I understand what you mean, the output window is a command prompt process that's created when you run your program and terminates when your program ends. Just hit F9 to compile and run, or choose the option you want from the Execute menu. But keep in mind that you'll need to use a trick to keep the window open long enough to read your output. The accepted solution is to ask for input:

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
#include <ios>
#include <iostream>
#include <limits>
 
void pause_program ( const char *msg )
{
  std::cout<< msg;
 
  // This might not work as advertised
  if ( std::cin.rdbuf()->in_avail() > 0 )
    std::cin.ignore ( std::numeric_limits<std::streamsize>::max(), '\n' );
 
  std::cin.get();
}
#include <ios>
#include <iostream>
#include <limits>

void pause_program ( const char *msg )
{
  std::cout<< msg;
  
  // This might not work as advertised
  if ( std::cin.rdbuf()->in_avail() > 0 )
    std::cin.ignore ( std::numeric_limits<std::streamsize>::max(), '\n' );
  
  std::cin.get();
}

I never liked Dev-C++'s debugging interface. I always drop down to the command line and use gdb directly rather than fiddle with it.

int main() {

It is portable, since it's on my laptop I can carry it around with me everywhere I go. :rolleyes:

>Very Expensive
Didn't cost me a dime to use. :rolleyes:

Or am I just clutching at straws here.

If your intent was to make people laugh then I guess you succeeded...otherwise I pity on you.

Are you thinking of the same system() I'm thinking of? Are you thinking? system("PAUSE") is not expensive. The amount of time spent waiting for user input is about 3000000000000000000000000000000000000000000000000000000000000000000000000 times (give or take a few dozen powers of ten) as long as the amount of overhead that system() produces.

Portability is not an issue here; a command line program to be ported to other platforms would have the end-of-program wait-for-input removed anyway.
