#include <stdio.h>

int main(int argc, char** argv)
{
	FILE *fp;
	char ch;
	fp=fopen("sub.c","r");
	ch=getc(fp);
	while(ch!=EOF) {
		if(ch=='/') {
			ch=getc(fp);
			if(ch=='/') {
				while((ch=getc(fp))!='\n') {
					getc(fp);//This commment wil be removed
				}
			}
			if(ch=='*')/*This also wil be removed*/ {
				while(1) {
					ch=getc(fp);
					if(ch=='*') {
						ch=getc(fp);
						if(ch='/') {
							break;
						}
					}
				}
			}
		}
		printf("%c",ch);
		ch=getc(fp);
