Bu soru 19.12.2010 tarihinde KingLion_m adlı kullanıcı tarafından sorulan bir sorudur.

Gelen Soru: Arkadaşlar bu programı Microsoft Visual Studio 2008 de nasıl yazabilirim?
Soru: Kendisine gönderilen 4 adet koordinat değerine göre (x1,x2,y1,y2) ekranın belirtilen bölgesine çerçeve çizen fonksiyon, main() fonksiyonu ile beraber çiziniz.
(Köşeler için 187,188,200,201 nolu ASCII karakterlerini, yatay çizgi için 205 karakterini, dikey çizgi içinde 166 karakterini kullanabilirsiniz).
Kolay gelsin.

Verilen Cevap:

Ascii karakterleri ile bir cerceve cizmek istedigimizde,kurgulamak istedigimiz sekil bir dikdortgen olacaktır.Eger tüm kenarları eşit bir dikdörtgen tasarlar isek buna kare cerceve de diyebiliriz.Her halükarda çizmek istedigimiz seklin ortası boş olacaktır.Yani cercevenin sadece koseleri ekranda 'monte' edilmelidir.Sorunun standart C++ dili ile yazılmıs algoritmasını asagıda yayımlıyorum,siz cout çıktı akışlarının yerine visual C++ output metotlarından bir tanesi uzerinde yazabilirsiniz.
#include <iostream>

using std::cout;

int main() {

int i,j;
       const int boy=15;
       cout << (char)218; // cercevenin sol ust kosesi

       for(i=0;i<boy;i++) {
       for(j=0;j<boy;j++) {
       if(i>0 && j>0 && i<boy-1 && j<boy-1) // cercevenin icinin boş olma ozelligi
       cout << ' ';
       else if(i==0 && j==boy-1) // cercevenin sag ust kosesi
       cout << (char)191;
       else if(i==boy-1 && j==0) // cercevenin sol alt kosesi
       cout << (char)192;
       else if(i==boy-1 && j==boy-1) // cercevenin sag alt kosesi
       cout << (char)217;
       else if(j>0 && j<boy-1)  // cercevenin alt ve ust kenarlari
       cout << '-';
       else if(i>0 && i<boy-1) // cercevenin sol ve sag kenarlari
       cout << '|';
       }
       cout << '\n';
       }
