What the hell happened to <iostream> (plain C)?

Did you paste the old text in instead of the fixed version?

You could always use your original example but use <stdio.h> functions rather than <iostream> functions.

Code:

$ cat ask.c
#include <stdio.h>

int main () {
   char ask[]= "Enter your first name: ";
   char answer[]= "So your name is ";
   char name[100];

   printf("%s", ask);
   scanf("%s", name);
   printf("%s%s.\n",answer,name);
}
$ gcc -o ask ask.c
$ ./ask
Enter your first name: Johnny
So your name is Johnny.
$

Unfortunately gcc has 2 different meanings, which is quite annoying. First: gcc stands for gnu compiler collection and (how to say) it is (more or less) a language-independent engine (to make executables from source code).
Furthemore gcc itself is one of the tools within gcc, the compiler collection, especially that is the gnu version of the good old c compiler.
If you want to use gcc (the compiler collection) you need to install the engine itself - which are the linker, the preprocessor, debugger among the lot of other goodies) and the language specific toolset too (like c, c++, fortran ... and/or whatever compiler you need).
The name of the c++ compiler is g++

yeah im pretty sure that all came with installing code::blocks, but i'm also curious about how people would use gedit and notepad and then just compile code straight from that

What do you mean how? The same way you've done at the start of this thread, except without mixing C and C++. If you want to use iostream, cin, cout, etc., that's C++, which means your code should end in .cpp and you should compile it with g++. If you want to use C, then the code should end in .c and you should use printf, etc.

in general gedit and notepad are not really used to write code, there are much better editors available exactly for that. Using one of those editors you will be able to "just compile code straight from that". Those are: vi (or vim), emacs, eclipse and a huge amount of other tools. They called IDE. (in MS Windows there is an editor called notepad++ which is also very good, because that is much more than a simple notepad).
So return back to your question: developers do not use gedit or notepad, but you can start using those and also write a makefile to compile and build your code.
