Help please

Program is in Dutch so if you want it to be English just say it.

Code:

#include <iostream>
using namespace std;

int main()
{
    // declaratie en initialisatie van pi end declaratie van straal:
    double pi = 3.14159265358979;

    cout << "Geef de straal van een cirkel in meters" << end1;
    cout << "en ik bereken de omtrek" << end1;
    cin >> straal;
    cin.get();                                //eind invoer

    cout << "De omtrek is: ";

    //declaratie en initialisate van omtrek:
    double omtrek = 2 * pi * straal;
    cout << omtrek << " meter";
}

So this are my errors:
C:\Users\***\Pictures\gta mods\emulators\C++\project 12.4\main.cpp||In function 'int main()':|

cout << "en ik bereken de omtrek" << endl; // E N D L

cin.get(); //eind invoer

cout << "De omtrek is: ";

}

what dot? ...

also change

cout << "en ik bereken de omtrek" << end1;

to

cout << "en ik bereken de omtrek" << endl;

thanks that is one error gone but still I got the error at

cin >> straal;

I tried code blocks and dev C++ and both give error I even tried to change straal to pizza but doesn't work please help me.

Like abuckau907 said you need to initialize the value like this

// declaratie en initialisatie van pi end declaratie van straal:
double pi = 3.14159265358979;
double straal = 0;

thanks bro, I had some few errors after but fixed them myself

REP+ for ya

cin >> straal;

You did not declare it buddy.
So why are you trying to use it. It's one of the basic you learn while learning C++.
You must declare a variable before you can use it.

Help please
