sudo dergisinde bugün rastladığım güzel bir komut ^^

c# windowsform

csharp beginner

```c++ using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks;

Go to settings > developer options > there you can see Super user setting click on that and select the option always allow. Then install SuperSU from Google play store and let the supersu’s binary update then you are rooted. Then open supersu and go to setting and scroll down to the option access > and set Default access to GRANT. Then you will have full root access, if you forget to give always allow and grant then your application which needs root will hang. Do not give prompt as option always allow and Grant will do..

Why does my program go into an infinite loop when someone enters an invalid input character?

```c++ #include using namespace std; void mainMenu() { int ch; cout<<"Main Menu"<<endl; cout<<"1. Customer"<<endl; cout<<"2. Item"<<endl; cout<<"3. Shopping"<<endl; cout<<"4. Quit"<<endl; cout<<"Choose one: "<<endl; cin>>ch; while( cin.fail() ) { cout << "Bad input, try again." << std::endl; // Reset the stream. cin.clear(); cin.ignore(std::numeric_limits::max(),''\n''); cin>>ch; } // until you enter integer value you will //try to input new value

lists with pointer // abstract classes

```c++ #include #include using namespace std; class Shape { public: Shape(int a,int b):x(a),y(b) {} virtual void display()=0; virtual void printArea()=0; protected: int x; int y; };

aggregation //how difficult to say =D

```c++ #include #include using namespace std;

how to use lists with abstract class

```c++ #include #include using namespace std;

output 3 virtuality

#include<iostream>
using namespace std;
class BC{
public:
void show_class(){
show1();
show2();
}
private:
void show1(){
cout << "#1 BC\n";
}
virtual void show2(){
cout << "#2 BC\n";
}
};
class DC : public BC{
private:
void show1(){
cout << "#1 DC\n";
}
virtual void show2(){
cout << "#2 DC\n";
}
};
class DDC : public DC{
private:
void show1(){
cout << "#1 DDC\n";
}
virtual void show2(){
cout << "#2 DDC\n";
}
};
int main()
{
BC b;
b.show_class(); // #1 BC, #2 BC 
cout << endl;
DC d;
d.show_class(); // #1 BC , #2 DC
cout << endl;
DDC dd;
dd.show_class(); // #1 BC , #2 DDC 
cout << endl;   // show_class is in BC class, so it shows its show1() function because of no virtuality
return 0;
}
