Question

Very simple C++ question. Basically why doesn't this work:

#include int num = 5; int *numPointer = # //cout << &numPointer << endl; cout << "Hello there" << endl;

Answer 1

u have to include the braces {

Answer 2

Netbeans has cout << "Hello there" << endl; in red underlined and it says "unexpected token cout. unable to resolve identifier cout"

Answer 3

hey there's a computer science group, you may post your question there
this group is only for math questions

Answer 4

u have to have the curly braces and also include void main ()

Answer 5

Oh I see. Is there a reason why I need void main(){}?

Answer 6

Tomas.A: I thought I was in the computer science group. Sorry, after this question I will go there.

Answer 7

I mean what is the reason

Answer 8

you can go straight away and i am sure agdwnwngo would help you

Answer 9

void main () is the part wherein the computer understands that the program has to be executed from that place the curly brace after that is where it starts execution from till the time the curly brace ends

Answer 10

Ok so even in procedural programming, we use that, right?

Answer 11

c++ is object orientated language

Answer 12

but it has c features so it can be procedural to my knowledge

Answer 13

i just don't know what that means in practice.

Answer 14

it has some modified terms and it has to be followed

Answer 15

it will be object orientated anyway but you can write code without using object (only main)

Answer 16

Also:
#include <iostream>

int void main()
{
int num = 5;
int *numPointer = &num;
//cout << &numPointer << endl;
cout << "Hello there" << endl;
return 0;
}
doesn't work: "Unable to resolve identifier cout". I am using netbeans.

Answer 17

using namespace std;

Answer 18

but java is fully object-oriented and i can write code just using the main method. but a lot of things have to be static afterwards. is that a difference between java and c++?

Answer 19

i meant int main() not int void main()

Answer 20

so you can do same thing in c++ too

Answer 21

you can write code just using main in c++ as in java

Answer 22

i'm not saying you can't in C++. I'm just asking if you're forced in Java to use static and in C++ you're not.

Answer 23

if you code all in main and use no objects that is.

Answer 24

idk im not very familiar with c++

Answer 25

o me neither. the real reason why i asked this question in the first place is to test the following:

Answer 26

#include <iostream>;

using namespace std;

int main()
{
int num = 5;
// int *numPointer = &num;
// Way 1
string str = &num;
cout << str << endl;

// Way 2
// cout << &num << endl;
// cout << "Hello there" << endl;
return 0;
}

Answer 27

Way 2 works as expected but way 1 doesn't.

Answer 28

ask in computer science group and u will get answer lol

Answer 29

i don't know pointers

Answer 30

Alright, thanks still.

Answer 31

(I asked it there)
