i am new to c++. i compiled my code in visual-studio-code in windows10, with 2 variables of type string and string\_view. string variable is fine, but string\_view is giving errors.I also enable c++17 extension in configuration.json and edit configuration/ui file in vscode.

Here is my code:=

```
#include<iostream>
#include<string_view>
using namespace std;
int main(){
      string str="hello";
      cout<<str<<endl;
      std::string_view sv=" world";
      auto result=str+sv.data();

      return 0;
}

```

errors are:=

```
main.cpp: In function 'int main()':
main.cpp:7:12: error: 'string_view' is not a member of 'std'
       std::string_view sv=" world";
            ^~~~~~~~~~~
main.cpp:7:12: note: 'std::string_view' is only available from C++17 onwards
main.cpp:8:23: error: 'sv' was not declared in this scope
       auto result=str+sv.data();
                       ^~

```
