@mainframed767 @smallsco Apple’s default/standard compiler for A/UX is K&R only, so it will compile only old/specially prepared C sources.

Then, there’s the “extra” ANSI compiler from Apple. http://archive.3rz.de/Mac/a-ux/A-UX%20Developer%20Tools%201.1%20(Apple%20ANSI%20C%20compiler).iso.gz that I archived from original CDs. It’s more capable and was part of the SDK for A/UX 3.

Or you could use gcc.

New video: Let's Code MS DOS 0x31: ANSI C Data Types

The C programming language has only few builtin data types. But for a beginner those can be a bit confusing. So we will have a look at what data types are offered, and what kind of new datatypes you can build with C.

#include <fun.h>
#include <familie.h>
#define newYear 2024

main()
{
gobalHappy=newYear;
printf("Lets rock");
}

#ansiC #newyear

Does anyone know why the C standards body went with the solution of those weird PRIu64 macros instead of a new format specifier like %j or whatever?

My google-fu is weak, can’t even locate a copy of the C99 standard that might maybe mention what this is for.
