A blog about programming and more programming.

Program without header file?

with one comment

So continuing in the series of program without, here are two more programs. The first one is just a valid C program without any header file.

int main()
    return 0;

The above program will actually compile and run. But you will say it did nothing. So lets have a program without header file which prints something.

extern "C"
       int printf(const char *format,...);

int main()
    printf("Hello World");
    return 0;

The only unexplained feature is extern “C”. For more about it read this.
