Explanation of ? operator missing in reference guide

Check the OPs posting history on this group and you will see that it
normally posts complete rubbish. The best thing to do is ignore it.

The intention ofcourse is to execute different code based on the value of A
like a case statement in pascal or a switch in C.

A = 4;

A ? B = 1; C = 2; D = 3; E = 4; F = 5;

A ? Init(); Work(); Draw(); Next(); CleanUp();

I would write that, this way:

     func[A]();

/* BEGIN new.c */

#include <stdio.h>

void Init(void);
void Work(void);
void Draw(void);
void Next(void);
void CleanUp(void);

int main(void)
{
     void (*func[])(void) = {Init,Work,Draw,Next,CleanUp};
     size_t A;

     for (A = 0; A != sizeof func / sizeof *func; ++A) {
         func[A]();
     }
     return 0;

}

void Init(void)
{
     puts("Init");}

void Work(void)
{
     puts("Work");

}

void Draw(void)
{
     puts("Draw");

}

void Next(void)
{
     puts("Next");

}

void CleanUp(void)
{
     puts("CleanUp");

}

/* END new.c */

Nice.
How about:

#include <stdio.h>
int Init(int i) { puts( "Init"); return i+1;}
int Work(int i) { puts( "Work"); return i+1;}
int Draw(int i) { puts( "Draw"); return i+1;}
int Next(int i) { puts( "Next"); return i+1;}
int CleanUp(int i) { puts("CleanUp"); return -1;}
typedef int (*ifi)(int);
int main(void) {
int A = 0;
while((A=A[(ifi[]){Init,Work,Draw,Next,CleanUp}](A))!=-1)0xF00L;
return 0;
}
