I found this problem on a site full of interview questions, and was stumped by it. Is there some preprocessor directive that allows one to read from standard input during compilation?

Write a small C program, which while compiling takes another program from input terminal, and on running gives the result for the second program. (NOTE: The key is, think UNIX). Suppose, the program is 1.c Then, while compiling

$ cc -o 1 1.c 
int main() { printf("Hello World\n"); } ^D 
$ ./1
Hello World

EDIT It turns out this question is an exact duplicate. How to write program during compiling?

Answer 1

#include "/dev/stdin" is the trick.

A silly interview question at best.

Answer 2

In the spirit of one-upmanship, I tried to make a more platform/environment-independent version. However, I got stuck here... so this is my question, what can I replace '???' with?

#ifdef _WIN32
#include ???
#else
#include "/dev/stdin"
#endif

EDIT: Thanks to ohmantics I can now get the job with:

#ifdef _WIN32
#include "CON"
#else
#include "/dev/stdin"
#endif
