I was over at a friends house who just got the MEGAMAX "C"
compiler for his 520ST. There seems to be a bug with the
printf function. For example:
#include <stdio.h>
main()
{
int c;
printf("Hello world\n");
printf("Enter a Char:");
c = getchar();
}
Does not Work until you put a "\n" in the second
printf statement.

p.s. We tried calling the program a.tos, but that did not help eithertim@ism780c.UUCP (Tim Smith) (03/26/86)
It sounds like stdout is buffered. Try saying fflush( stdout ); before the getchar(). -- Tim Smith sdcrdcf!ism780c!tim || ima!ism780!tim || ihnp4!cithep!tim

That is not a bug. Printf write to stdout which is a bufferwed stream. So if you want the prompt to appear before the getchar() you will have to flush the stream something like printf("Enter a Char:"); fflush(stdout); c = getchar(); I tried it just now, and it works. -- Jwahar R.
