Change the name of output file

Hi All,

I have a program which takes a file as input and generates a output file with name FILExxx. The name of output file is hardcoded, and the name is same, whatever inputfile may be.

What I want is, if the input file is test, the output file should be named test_new, If the input file is myprog, the output file should be named as myprog_new.

Quote:

the input file is in some other location i.e.,
./myprog /data/tool2006/Myfile
so, when i do strcpy and strcat and compile the program, the output is generated in the path - /data/tool2006/Myfile_new

I want it in the current directory.

it is taking the whole path for strcpy, instead of only file name. how do i cpy only the file name

Thanx
jazz

Take the whole name of the input file, and append "_new" to the end of it. Use strcat().

Use strcat.
char * strcat ( char * dest, const char * src );
It appends src string to dest string. The terminating null character in dest is overwritten by the first character of src. The resulting string includes a null-character at end.

Parameters.

dest
Pointer to a null-terminated string with enough space allocated to contain both src and dest.
src
Null-terminated string to append.
Return Value.
dest is returned.

Portability.
Defined in ANSI-C.

Example.

/* strcat example */

#include <stdio.h>

#include <string.h>



int main ()

{

  char str[80];

  strcpy (str,"strings  ");

  strcat (str,"have been ");

  strcat (str,"concatenated.");

  puts (str);

  return 0;

}

Output:
strings have been concatenated

With a prefix of './' on the new filename, it will be placed in your current directory.

ex: ./myFile.txt
