Buy original books (foreign) at very low price in Bangladesh

Recently, a book named "COMPUTER ORGANIZATION AND ARCHITECTURE(8th Edition) by William Stallings " was needed to buy for my study and that's why i went to Nilkhet to buy the original copy of the book. But the book was not available at every bookshop and hardly i got a book but the seller wanted 650Tk. for this. Then another good seller gave me a advise to go to a shop where any foreign books can be purchased at the same price of rupee and then i went to that shop and bought the book at the price of 400Tk.(399Rupee).From then,i suggest every of my friends to visit the shop.Here,i have attached the address of the shop for everybody.

Implementation of Tic-Tac-Toe game (Human-to- Human) in C++

This is a simple tic-tac-toe game in c++ which i have collected from the web. I have edited it for myself and it is working 100% perfectly.You can also enjoy it :-)

Code:

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

void Board();
void PlayerX();
void PlayerO();
void Player_win();

char name_X[20];
char name_O[20];
int pos_for_X[3][3];
int pos_for_O[3][3];
int pos_marked[3][3];
