compiled but unrunable code

Hi

I am just starting out using cprogramming.com's tutorials. This is my second program, it is supposed to get a number by the user then say the number back.
Pretty simple, it is almost a carbon copy of the given code, it compiles but it does not run.

Code:

---


#include <stdio.h>

int main()
{
  int this_is_a_number;

  printf( "Please enter a number: " );
  scanf( "%d", &this_is_a_number );
  printf( "You entered %d", this_is_a_number );
  getchar();
  return 0;
}

I am using gcc on Mageia to compile, all I do is open up a terminal write "gcc Reading_numbers.c" in the teminal and press enter. It instantly spits out a file called a.out. That is the beginning of the trouble, I don't know what to do next to get it to work. I know that something I am doing is wrong but I am clueless, I have looked at other people's problems but cannot seem to find one that will help me

Now you type in the same terminal window
./a.out

Thank you

I was so confused I even tried to run it through the conpiler again as a.out. Seeing it was such a simple answer I feel rather silly now. Thanks for explaining.
