FILE HANDLING

Hi I am a little bit new to C's advanced topics:
I need help in file handling.
I have Turbo C and I wrote a simple program to write data to file:

#include<stdio.h>

#include<dir.h>
#include<conio.h>
#include<stdlib.h>

// program to write your name to a file
void main()
{ FILE *pt;
char *b;
chdir("d:\test");
pt=fopen("bharat.text","w");
printf("ENter ur name ");
scanf(" %[^\n]",b);
fprintf(pt," %s",b);
fclose(pt);
getch();
}

When I executed the program, a new file("bharat.text")was created in
the BIN directory under the Turbo C directory. I wish that the file
should be created in "D:\TEST" folder.
Can any one tell me how to do that?

Change "d:\test" to "d:\\test" or "d:/test".

#include<stdio.h>

#include<dir.h>
#include<conio.h>
#include<stdlib.h>
<dir.h> and <conio.h> are non-standard headers.
// program to write your name to a file
void main()
Make that "int main(void)".
{ FILE *pt;
char *b;
chdir("d:\test");
The "\t" expands to a tab character. If you want a backslash
character in a string, you need to double it:

chdir("d:\\test");
pt=fopen("bharat.text","w");
printf("ENter ur name ");
Apart from the misspellings, stdout is typically line-buffered, so the
message may not appear before the scanf(). Add
fflush(stdout);
scanf(" %[^\n]",b);
fprintf(pt," %s",b);
fclose(pt);
getch();
getch() is a non-standard function.

You should have a "return 0;" here.
}

You'll get the usual:

Not portable. Can't discuss it here. Blah, blah, blah.

but see below anyway...
Change "d:\test" to "d:\\test" or "d:/test".


Or, more to the point, get in the habit of checking the return value of
system/library calls.

In addition to everything Keith pointed out, you have a real problem.
You have defined a pointer to char, b, but have not created any
characters for it to point to, nor have you initialized it to point
anywhere.
