Every year I start trying to learn C and quickly hit some snag or other...
Hopefully, someone can point out what I'm doing wrong so that I can
progress a little further this year.

In Chapter 1 of Herbert Schildt's 'Teach Yourself C' there is a simple
illustration of scanf :-

#include 

main()
{
        int len, width;

        printf("Enter length: ");
        scanf("%d", &len);
        printf("Enter width: ");
        scanf("%d", &width);

        printf("area is %d", len * width);
}


This is supposed to prompt the user for two values and compute the result.

When I run this program, I don't get any prompts, before entering any
values. Is this just a quirk of using an OS/2 compiler, or is Mr. Schildt
in error here?

I'm using ICC from C Set/2 v1.0 and this is what the output looks like:-

[F:\dev\c]ex3
12
15
Enter length: Enter width: area is 180
[F:\dev\c]
