Pragma issue

akashj87 · #1 03-Mar-2009, 12:28

I wrote the following program ;

CPP / C++ / C Code:

#include<stdio.h>
#include<conio.h>
void test_p();
#pragma startup test_p
int main()
{
  printf("i am in main");
  return 0;
}
void test_p()
{
printf("i am outside main\n");
}

As expected i should receive the output as
I am outside main
I am in main

But i am receiving linker error in turbo c 4.5 and output ("i am in main") in Devcpp

can you please tell me what went wrong ?

Please be descriptive, i am novice in programming

You are learning non-standard implementation-dependent features of a very old compiler.

Compilers are not required to recognize pragmas like this, so what's your point?

If you don't have a book and can't get one, why not try to find a tutorial that covers standard language features.

For example, you might start somewhere like this site: http://www.cplusplus.com/doc/tutorial/

If modern tutorials cover features that old compilers like yours don't implement, you might want to try to upgrade.

A search for threads on gidforums containing "download free compilers" gave the following link: http://www.gidforums.com/t-14630.html

If you are particularly attached to Borland, I would add http://www.turboexplorer.com/downloads to that helpful list for a (free) download of Borland's latest and greatest.

Regards,

Dave
