Is this program having any sequence point issues?

Question

#include
 int main()
 {  
       int i=7,j;
       j=(i++,++i,j*i); 
       return 0;
}

j=(i++,++i,j*i);Is this well defined ? Let m

Answer 1

In your code " ," will be work as sequence point.

so in this

j=(i++,++i,j*i);

expression would be work from left to right.
so at first i++ then ++i and then j*i

at the last j*i would be stored in j;

but lastly your result would be elegant because " j " have no predefined data
so undefined value would be stored in j.

if you don't use " () "

your code would be work as single statement such as

j=i++;
++i;
j*i;
