Question

I’m trying to run a simple Hello World! program on a Fedora Linux system through the terminal using gcc, and get the following:

[abder-rahman@Abder Desktop]$ gcc hello.cpp

hello.cpp:1:22: fatal error: iostream.h: No such file or directory compilation terminated.

Why is that? What is going wrong?

Thanks.

Answer 1

1. You should compile C++ programs with g++, not gcc.
2. There’s no iostream.h header in standard C++. It’s iostream (though iostream.h may be offered for backwards compatibility with ancient C++ code).
