Additional context

compiler shows errors but visual studio code editor does not show any basic errors in syntax

For Example:

#include <iostream> using namespace std; int main() { cout << "Line One\n"; cout << "Line Two\n" cout << "Line Three\n"; return 0; this is a comment with out "//" }

NO Formatting or shows syntax error by editor

Hi @Fady2007 . I noticed that you're trying to #include <iostream>, however I don't see a compiler specified in your configuration. In order for IntelliSense to find system headers, a compiler toolchain (and its headers) need to be located on your system. The C/C++ Extension does not currently bundle a free C++ compiler. Do you have a C++ compiler installed? If so, could you try specifying it in your configuration using the compilerPath field?
