Thread: program to remove comments from source

Hi Iv been working on a program that opens a source file then copy's the src to another file excluding all comments. I have the idea and the concept, and have written this src:

Code:

#include <stdio.h>
#define IN 1       /* getc() is now reading comment(not outputting text) */
#define OUT 0      /* getc() isn't reading comment(outputting text) */

int main() {
   int mode, l, j, k;
   FILE *src, *newSrc;
   
   src = fopen("C:\\1-23.c", "rt");
   newSrc = fopen("C:\\src.c", "wt");
   mode = OUT;
   for (;;) {
      /* Entering comment */
      if ((l = getc(src)) == EOF) {
         printf("l End of file reached");
         break;
      }
      if ((j = getc(src)) == EOF) {
         printf("j End of file reached");
         break;
      }
      if (mode == OUT && l == '/' && j == '*') {
         mode = IN;
      }
      else if (mode == OUT && j == '/') {
         k = getc(src);
         if (k == '*') {
            mode = IN;
         }
         else {
            putc(j, newSrc);
            putc(l, newSrc);
            putc(k, newSrc);
            break;
         }
      }
      else if (mode == OUT) {
         putc(l, newSrc);
         putc(k, newSrc);
      }   
      /* Leaving comment */
      if (mode == IN && l == '*' && j == '/') {
         mode = OUT;
      }
      if (mode == IN && j == '/') {
         k = getc(src);
         if (k == '/') {
            mode = OUT;
         }
      }
   }
   fclose(src);
   fclose(newSrc);
   getchar();
   return 0;
}

I'm sorry if there's anything hard to understand in the source because i didn't write any comments. When i run this, it creates a blank file with weird characters in it. Can anyone please find were this bug is?
