Thread: [Dev-C++] (no subject)

Hello people!
I am Dr. Jones, from Brazil.
I have programmed for +/- 1 year in QB4.5, one more year in VB5, and =
since some time ago I try to begin programming in C/C++, Assembly or =
Pascal. I think Assembly will have to wait until I got to learn one of =
the other two, so C/C++ and Pascal remain.
I have tried some Pascal compilers (like Turbo Pascal and Free Pascal), =
but I have never got the compilers even to run a single "Hello, world!" =
program. As for the C/C++ compilers, I have been more lucky. I have =
tried Turbo C, Miracle C, Quincy (a nice C INTERPRETER, not a compiler), =
and the great DJGPP, with RHIDE. I have got all them to work, and all =
these are very good. (Although Turbo C was some strange to use, and =
Miracle C seemed to be corrupted and did not work properly). And the =
wonderful LCC-Win32 and V. But Dev-Cpp is the best and easiest to use =
C/C++ compiler/IDE I've ever tried! Although I think DJGPP or Watcom (I =
have never got this last, however) are more "powerful", or =
"professional", and LCC-Win32 and V can (in my opinion) replace even =
Microsoft Visual C, with its ability to create Windows GUI programs, no =
one of them is easier to use than Dev-Cpp. As a new user to C/C++, this =
is the best for me. And I see day by day that it is not just an "easy" =
system to use, I feel more and more that I am going to use it =
definitely.

P. S.: Do you know of any tutor/sample program that can guide a VB =
programmer into the great world of C/C++?
I know up to now just the basic commands...

i have a program that asks the user to enter some numbers, finds the answers and reports them.  at the end i used the 

system("pause")

function which asks the user to press a key and then it closes the program.  Is there anyway to get the program to just keep returning to the beginning without having to restart it?  

Thanks

Hi,
I have just started using devcpp4 and have successfully written some =
basic programs. I am having a problem when executing programs. The =
program runs but the window immediately closes after the program has =
finished running and I cannot see the results of the program. Is there =
anyway to keep the window open after the program has finished running.
Thanks.

Mark,

At the end of the program under main, before return 0;, put in =
getchar().  That'll require an input from the keyboard before any other =
action will be taken, and in this case, shutting down the program.

(Make sure to include iostream.h and stdlib.h)

As I've recently asked this question, I'll pass on the info I was =
provided and which has worked for me....

quoted from Spiderman's response to my question:

    Include stdlib.h then at the end of your program write: =
system("pause"); here is an example:

#include <iostream.h>
#include <stdlib.h>

void main()
{
    cout<<"Hello world!\n";
    system("pause");
}

Hi

Has someone ever compiled the FOX toolkit library using the dev-c++ =
environment ? The FOX web site said it could be done using the mingw32 =
compiler, but I don't know if it could be done using the IDE.

thanks

Here is a sample of one way towrite to a text file . There areseveral other
ways. See your documentation.
#include <stdio.h>
#include <string.h>
#include <stdlib.h>

FILE *frw;

void  main(void);

void  main(void)
{
   char   save[51];

   if ( (frw = fopen("fname.txt", "r")) == NULL){
      puts("Can not open winning database");
      exit(0);
      }
   strcpy(save, "Hello World");
      fwrite(save, sizeof(save), 1, frw);

}

Corrected input: Sorry , in the first submission I forgot to put the "+" in
the fopen statement. This allows both read & write.
#include <stdio.h>
#include <string.h>
#include <stdlib.h>

FILE *frw;

void  main(void);

void  main(void)
{
   char   save[51];

   if ( (frw = fopen("fname.txt", "r+")) == NULL){
      puts("Can not open winning database");
      exit(0);
      }
   strcpy(save, "Hello World");
      fwrite(save, sizeof(save), 1, frw);

}

Hi:

I am trying to migrate a program written under Linux C, to compile & run =
it under Windows. I am finding problems with the sockets libraries. (I =
take it they are different). Can anybody tell me some about the socket =
lib in dev C++.? Will the functions be different ?

thanks

I’m trying to add another feature to my primitive program :O) I was trying
to add a regular calculator allowing a choice from the quadratic equation
calculator and from a regular arithmetic calculator I keep getting two
errors which I marked in the code below I’m still a beginner so I as if what
I’m trying to do even possible if not can I have a program open either one
(each in its own executable) if so how? Thanks

Hi
I am a student learning c++ and have written a program to displace =
fibonacci numbers till the value entered by the user. This program =
doesnt compile in DevC++ showing some linker errors however it does =
compile in Visual c++. Any Ideas on whats wrong ?
Thanks
Devik

Here's the code

/* This Program Displays N Fibonacci Numbers */
#include<iostream.h>


void main()
{
int c,a=3D1,b=3D1,newno,n;
cout<<"Enter the value of n ";
cin>>n;
cout<<"\nThe N Fibonacci Numbers are \n";
cout<<a<<" "<<b<<" ";
for(c=3D2;c<=3Dn;c++)
{
newno=3Da+b;
a=3Db;
b=3Dnewno;
cout<<newno<<" ";   }

}

Hi Devik,
I copied and pasted your code below and compiled it using Dev-C++ and =
there were no errors found.  It compiled fine but I could not run it =
successfully (which must be a problem with my compiler - as all my =
programs have compiled fine but refuse to run).  Best of luck!=20

how can i cout 1 message and then another in the same place as the first?
