Ödev1 (Homework): if ( (x==5) && (y>x) )
7. Örnek: Switch: (Değer bir ise bunu 2 ise şunu yap gibi)
#include <iostream>
using namespace std;
int main()
{
unsigned short int mk;
cout<<"0 ile 5 arasinda bir sayi seciniz :\n ";
cin>>mk;
switch (mk)
{
case 0: cout<<"Hayirli gunler dilerim\n";
break;
case 1 : cout<<" Gunaydin !!!\n";
break;
case 2 : cout<<"ikindi cayina bekleriz !!!\n";
break;
case 3 : cout<<"Aksam yemegine gelermiydiniz !!!\n";
break;
case 4 : cout<<"Yatiyada kalsaydiniz bari !!!\n";
break;
case 5 : cout<<"Gitmeyeceksiniz gibi gözukuyor bari biz kovalim !!!\n";
break;
default: cout<<"Lutffen 0-5 arasinda sayi seciniz\n";
}
cout<<"\n";
return 0;
}

8. Örnek: While (iken : 10'dan kükük se şunu yap)
#include <iostream>
using namespace std;
int main()
{
int mk = 0;
while(mk<=10) /*mk 10'dan küçük veya eşitse döngü 10+1=11 olanakadar devam eder*/
{
mk++; //mk'yı bir artırır.
cout<<"<mk : "<<mk<<"\n";
}
return 0;
}

9. Örnek For
#include <iostream>
using namespace std;
int main()
{
int mk;
for (mk=1; mk<=10; mk++) /*mk'yı 1 olarak al 10' akadar birbir arttır*/
{
cout<<mk<<"\n";
}
return 0;
}
