could not creat process?!

[samiei]

i would be plzed that some1 tells me why doesn't my program run?and gives this massege "could not creat process!"

#include<stdio.h>
#include<stdlib.h>
#include<conio.h>
struct list {
          char alph;
          int freq;
};
struct list a[256];
///////////////////////////////////////////////////////////////
int main(){
          int j,m,f,k;
          FILE *fin;
          char ch;
          clrscr();
          fin=fopen("a:test.txt","wt");
          printf("\n enter characters($ for end):");
            do{
                ch=getchar();
                putc(ch,fin);
              }while(ch!='$');
          fclose(fin);
          fin=fopen("a:test.txt","rt");
          for(j=0,m=0;j<256;j++)
          {     f=0;k=0;
                     while((ch=getc(fin))!=EOF)
                     {
                        if(ch==j)
                        { f=1;
                          a[m].alph=ch;
                          k++;
                        }
                     }
                     if(f==1){
                        a[m].freq =k;
                        m++;
                     }

                     rewind(fin);
          }
          fclose(fin);
          getch();
            return 0;
}

Which compiler and OS are you running it on?

[Brian]

Could someone translate?

[Dante Shamest]

Did you compile your program?
If so, which compiler did you use?
Did it generate any errors?
What operating system do you run?

[Salem]

Probably typed
prog.c

Rather than say
gcc -o prog.exe prog.c
prog.exe

[itsme86]

Wouldn't that just result in a "command not found" error? It sounds to me like he's possibly compiling it into an executable format that's not supported by the OS. But since he came on with a worthless question and hasn't returned to actually fill in any of the blanks we'll probably never know.

[samiei]

thx for all that trying to help.
i'm using win xp.
and turbo c++ and saved my program with the extension CPP.i copiled my program and it doesn't have any errors!

appreciate your help

Interesting!
I'm writing a simple database program for console and want to make graphical interface. I have Visual Studio .net, Dev-Cpp and Turbo C and interesting I found that turbo C 2 because of it library graphics and many useful functions is more suitable for my task than any of "newer" compiler. Too bad it is written for 16 bit OS and sizeof(int) is 2 bytes.
I think we should not underestimate the power of older comiplers such as Turbo C. It makes a life easier if you want to make graphical interface for console. At least that is my experience.

[Salem]

I seriously doubt that there is anything you can do in TC which can't be done in a host of modern 32 bit graphics libraries for the sake of a bit of reading.

[andyhunter]

for the sake of a bit of reading.

And I think we have a winner!

Its obvious that people just don't want to bother to try and learn how to program for the console, hence the 'I like the older compilers better' comments. It really isn't that hard but it does require a little effort, alas what are you going to do.

Here is adrianxw's console tutorial yet again for those that want to begin to understand console programming.

Cannot create process is not because he is using Turbo C++.

Cannot create process means that normally the process is already running and cannot have multiple instances running at the same time. If you code something in MSVC, run it, and forget to shut it down, recompile it and execute...you will get this error.

Bring up the task manager and kill the other instance of the application and execute it again. Often what happens is the window for the other process has either disappeared or the program does not appear on the task bar, but is still an executing process - this usually happens because of a major bug in the code.

DOS Turbo C++ version 1.0 thru version 4.52 all work perfect under XP. Interrupts work flawessly (software interrupts at least). You will have trouble with executing some DOS functions off of the DOS interrupt and you will certainly have trouble with directly accessing certain memory. You also cannot program the DMA and/or program sound cards due to the fact that hardware interrupts and the like don't work as expected.
