Syntax question

I'm really astonished and cannot figure it out ...

Code:

---

bool Mybool[10][5];
int x,i;

...
if (!Mybool[x],i) { ... }

---

My intention was obviously to write !Mybool[x][i] but the compiler didn't detect any error ... and I spent a lot of time until I found the mistake.

My question ... what is the compiler doing with this incorrect syntax?:confused:

Thks

so whats an issue ??

well ... I would like to understand/know what is being compiled when an

if (expresion1,expresion2)

is written.

Just "to know" if you like it that way.

Expression 1 is evaluated, then expression 2. The result of expression 2 is used by the 'if' to determine program flow.

Your original code is equivalent to...

Code:

---

!Mybool[x];

if (i) { ... }

You've stumbled onto the ',' operator. That's why there was no compile error.
