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)
{
/************************/

}
return;
}
