Problem learning Namespace in C++

Question

This is my C++ code:-\

#include<iostream>
using namespace std;
namespace new1
{
void func
{
std::cout<<"new1";
}
}
namespace new2
{
void func
{
std::cout<<"new2";
}
}
main()
{
std::cout<<"In main.";
new1::func();
}

And this is the error message:-

..\Playground\:5:7: error: variable or field 'func' declared void
void func
^
..\Playground\:7:20: error: expected '}' before ';' token
std::cout<<"new1";
^
..\Playground\:9:1: error: expected declaration before '}' token
}
^

Can anyone explain what is wrong here?

Answer 1

Please link the code from the playground in the future.

Posting code directly inside the thread is messy.

Answer 2

Do this for classes.

Class new1
{
public:
// functions
//edit
};

Answer 3

Hm, where are sintaxes error in your code, you need to write void func() {} and it will be ok. Namespace is ok, and use certainly soo.

Answer 4

I was wrong.

@Shaldem

I did not know namespace, could be used like that.

Thank you for the info and sharing your code!

Answer 5

namespace new1;

Does not exist. Delete it.

You should have used Class there.

namespace is not used like that.
