Problem learning Namespace in C++

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?

Please link the code from the playground in the future. Posting code directly inside the thread is messy.

Do this for classes. Class new1 { public: // functions //edit };

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. https://code.sololearn.com/c8f4V61yovz3/?ref=app

I was wrong. @Shaldem I did not know namespace, could be used like that. Thank you for the info and sharing your code!

namespace new1; Does not exist. Delete it. You should have used Class there. namespace is not used like that.
