Thread: Pointers

Hello, I have got a question about the pointers. Example: #include using namespace std; void main() { int a = 3; int &b = a; cout Wtf all I wrote is in one line????? In attachments is what I really wrote. I don't know what is wrong with this board?!?

Code:

#include <iostream>

using namespace std;

void main() {
	
	int a = 3;
	int &b = a;

	cout<<b<<endl;
	system("PAUSE");
}

What do you mean how would it look like with a pointer??

Yes I can just get the adresse of an variable but not the value in it.

int *b = &a;

Well thats exactly my problem :-). b points now at the adress of a but it wouldn't output the variable a....

Well,

Code:

#include <iostream>

using namespace std;

void main() {
	
	int a = 3;
	int &b = a;

	cout<<b<<endl;
	system("PAUSE");
}

works fine (reference - This is not a pointer):

Code:

3
Tryck ned valfri tangent för att fortsätta...

Code:

...
	int *b = &a;

	cout<<b<<endl;
...

gets the address, is that what you want?

Code:

Tryck ned valfri tangent för att fortsätta...

Code:

...
	int *b = &a;

	cout<<*b<<endl;
...

works fine (pointer):

Code:

Tryck ned valfri tangent för att fortsätta...

I'm really not sure what you're trying to acheive.

Nvm I've got it :-) Thank you muppertalert.
