fwrite problem

i am trying to write 2 strings to a file ,however after each string has been written i want to start a new line , i know that "\n" is the newline character however whenever i try and fwrite this it wont work. here is my code:

Code:

---


#include <string.h>
#include <stdlib.h>
#include <stdio.h>
#include <ctype.h>

FILE write(FILE *f, char *operand)
{ 
    fwrite(operand, 1, (strlen(operand)+1), bo);
   
}

void test()
{
    FILE *f;
    if ( ( f = fopen("test.txt", "r+b" ) ) == NULL) {
            printf( "File Cannot Be Opened\n" );
    }
    int a = 1;
    int b = 2;
    if( a == 1){
      char a[20];
      strncpy( a, "00000", 20 ) ;
      write(f,a);
    }
    if( b == 2){
      char b[20];
      strncpy( b, "11111", 20 ) ;
      write(f,b);
    }   
}
int main(void)
{ 
    test();
}

the file test.txt currently shows 0000 11111 , however i want it to show:

00000
11111

how can i put newlines in? thanks.

>how can i put newlines in?
'\n', perhaps?

From what it looks like, it might be asier to write in ascii format, not binary. Unless you have your reasons for using binary.

do i need to write the '\n' as a character or as a string? i'm assuming as a character, however doesnt fwrite only write strings?

u cant do that puting newline in bimary format, i have opened the file in ASCII format

Code:

---

  if ( ( f = fopen("test.txt", "aw" ) ) == NULL)

---

and this is a code to intsrt a new line

Code:

---

FILE write(FILE *f, char *operand)
{ 
    fwrite(operand, 1, (strlen(operand)+1), f);
    fputc('\n',f);
     
}

Code:

---

{
  char c = '\n';
  fwrite(&c, 1, 1, f);
}
