Explanation / Answer
Header parts being used deosnt exist in standard c++. they were part of some pre-1990s compilers, but it is certainly not part of C++.
conio.h is a C header file used in old MS-DOS compilers to create text user interfaces. Compilers that targeted non-DOS operating systems, such as Linux, Win32 and OS/2, provided different implementations of these functions. Same applies to iostream as well.
Remove .h and use #include <c> #include <iostream> instead. And all the library classes are in the std:: namespace, for example std::cout. Install required libraries .
Also how are you using the file , as .c or .cpp ? If it's a .c file, then your compiler may be interpreting it as C, and not C++. This could easily cause such an error. your default "include" directories for the standard library may not be set up right, but I don't know how you'd fix that, as that'd be compiler/environment dependent. try saving the file as .cpp and compile again.
