ok here is what it says ... Declaration is not allowed here

ivan · Oct 27th, 2005, 5:37 PM

Here is what I have changed and now it works:

#include<math.h>  
#include<stdio.h>  
#include<stdlib.h>  
#include<conio.h>    
int main()  
{  
    system("cls");  
	int i;
  	for (i=1;i<10;i++)  
    {
   	printf("the values of the square root of %d is %d \n",i,sqrt((double)i));    
  	}
  
 }

Worked fine with TurboC V 1.01 for me.

Am I the only one that read Narue's post? Narue is right:

(Toggle Plain Text)

#include<math.h>  
#include<stdio.h>  
#include<stdlib.h>  
#include<conio.h>    
int main()  
{  
    int i;
  
    clrscr();

    for (i=1;i<10;i++)  
    {
        printf("the values of the square root of %d is %d \n",i,sqrt((double)i));    
    }

     return 0;  /* I added this too */
}

In C, you have to declare all your variables before executing anything. i's declaration was after the call to clrscr() so it was illegal.

That's strange !!! I can declare vari anywhere I wann and it make no err

>That's strange !!! I can declare vari anywhere I wann and it make no err
It's not strange at all. You're compiling as C++, not C.

But the asker say he using Turbo C 3.0 it is --> C++

it works if it i use b4 the clrscr ();

This thread is indicative of exactly what a thread should not be. Except for Narue's correct posts, it is largely a recommendation to the OP that he/she indulge in voodoo programming. That sucks. As to ASMvsC++'s last post: most C++ compilers are capable of compiling a program as either C or C++. The choice between the two may be made in various ways (including, sometimes, the file extension).

All that's saying is that clrscr() is not defined. Add this under your includes...

#ifdef WIN32
#    define clrscr() system("cls")
#else
#    define clrsrc() printf("\033c")
#endif

if i work in windows environment, does it automatically defines WIN32, or do i have to compile in the following manner:

gcc a.c -DWIN32
