Removing text between /* */ in a file

Well, the program is designed to remove any text between the /* and */ in a text file input and also to give output of the original text. Copying the original text was easy, but I'm having trouble 'removing' text in between the /* and */ in a text file.

Say for example, a.txt had this:
/* Blah2 */ text /* /* Blah */ */

The output should be:

text /* Blah */

Heres wat I've done so far, I'm having trouble checking for /* and */ since they are 2 characters and getc() only returns one.. so any ideas?

Code:

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

// Formatting Constants
#define LINE "----------------------------"

// FILE* is a pointer variable
void original(FILE*);
void extractor(FILE*);

int main(int argc, char **argv)
{
	// Point to a File
	FILE *fp;
	fp = fopen(argv[1],"r");

	if (argc != 2)
	{
		printf("Please input a text file (one is required no more)\n");
	}
	else 
	{
		fprintf(stdout, "Removing /* and */ signs from %s...", argv[1]);
		// Check for contents in file
		fprintf(stdout, "\n");
		fprintf(stdout, "%s\n",LINE);
		fprintf(stdout, "Original contents of: %s\n",argv[1]);
		// Print out original contents
		original(fp);
		// Print out extracted (modified) contents
		fprintf(stdout, "%s\n",LINE);
		fprintf(stdout, "Extracted contents of: %s\n",argv[1]);
		extractor(fp);
		// Close file
		fprintf(stdout, "%s\n",LINE);
		fclose(fp);		
	}

	return 0;
}

void original(FILE *fp)
{
	int c;
	while ((c = getc(fp)) != EOF) 
	{
			putchar(c);
	}
	return;
}

void extractor(FILE *fp)
{
	int c;
	while ((c = getc(fp)) != EOF)
	{
		
         /************************/
         /* NEED TO FINISH THIS PART */
         /************************/

	}
	return;
}

Basically, you want to update a boolean flag inside that loop
int inComment = 0;

Some conditions inside the loop will make inComment = 1, and others will make it inComment = 0

You output a char when
if ( !inComment ) putchar( c );

Start by writing some code which recognises when a / is followed by a *

Hi,

Looking at your string

/* Blah2 */ text /* /* Blah */ */

Shouldn't the output be

text */


because

/* Blah2 */ text /* /* Blah */ */
********---------------------------- is the first pair of /* */

/* Blah2 */ text /* /* Blah */ */
---------------**********------is another pair of /* */

This leaves "test" and the last "*/"


Just wondering.
