How Can I write strings in a new line with C Ansi ?e

I wanna write string in a new line. How can i do that ?


int main(int argc, char* argv[])
{
FILE *ponteiro_arquivo;

int i =0;

strcpy(sLinha, "0001 123456 nf 0,12\n"); /* copy 1 line*/

for (i =0 ; i < 5; i++)
if((ponteiro_arquivo = fopen ("c:\\gravar.txt", "w"))!= NULL){
fprintf(ponteiro_arquivo, sLinha);
/*always writing only the last line */
fclose (ponteiro_arquivo);
}


Thanks for help me

You are overwriting the file in each iteration of the loop. Try moving the open and close statements outside of your loop.

Or you can open the file for "write/append", in which case your printf will simply add a line at the end of the file. In your example, both of these methods would produce the same output.

Hope this helps,
Cedric

THANKS FOR YOUR HELP... IT'S RUN NOW.

I JUST OPEN THE FILE WITH OPTION "a".

it's still bad because it leaves with a lot of opened files hanging around - VERY bad! And it causes you to reopen it often - VERY slow!

Code:

---

int main(int argc, char* argv[])
{
FILE *ponteiro_arquivo;

int i =0;

strcpy(sLinha, "0001 123456 nf 0,12\n"); /* copy 1 line*/
if((ponteiro_arquivo = fopen ("c:\\gravar.txt", "wt"))== NULL)
{
  printf("Error!\n");
  return -1;
}
for (i =0 ; i < 5; i++)
{
fprintf(ponteiro_arquivo, sLinha);
/*always writing only the last line */
}
fclose (ponteiro_arquivo);
// ...
