Java File operations in C pgm

i am reading and writing to a a file in C language. the input file is described as follows

111 aaa descr1
222 bbb descr2
333 ccc <SPACE> {6 spaces are left after ccc i.e in 3rd column}
444 ddd descr4

when i read and write to a file, the space is not coming in the output file.
111aaadescr1222bbbdescr2333ccc444ddddescr4

Expected output:
111aaadescr1222bbbdescr2333ccc 444ddddescr4

Can somebody help me in modifying the code?

Code:
#include<stdio.h>
#include<conio.h>
struct buffer {
       char data1[255];
       char data2[255];
       char data3[255];
};
int main(int argc, char *argv[]){
 
 struct buffer dat;
  char *line = NULL;
   FILE *inFilePtr;
   FILE *outFilePtr;
  inFilePtr = fopen("test.txt", "r+");
  outFilePtr = fopen("out.txt", "w+");
   while (!feof(inFilePtr)){
      fscanf(inFilePtr, "%s", &line);
      printf("%s", &line);
      fprintf(outFilePtr,"%s", &line);
   }
   fclose(inFilePtr);
   fclose(outFilePtr);
 getch();
 return 0;
}

fscanf skips over blanks. Experiment with this
Code:
char tmp[80]={0x0};
while fgets(tmp, sizeof(tmp), inFilePtr)
{
    fprintf(outFilePtr, "%s", tmp);
}

hi Jim,
fgets is not working. the output is same as the input

111 aaa descr1
222 bbb descr2
333 ccc <SPACE> {6 spaces are left after ccc i.e in 3rd column}
444 ddd descr4

That's exactly what you asked for -- spaces in the output, just like the input.

If that's not what you want now, what do you want instead?
