Question

int main()
{
int i,j,s;
i=0;
j=(0,23);
A:
printf ("%d\n",i+=5);
printf ("%d\n",i-=7);
if (i<=5&&i>=-5)
goto A;
s=((i!=j)&&(j));
printf ("%d\n",s);
return 0;
}

Answer 1

Yes @Daniel, ',' operator execute all statements but return the result of the last one, here 23

Output :
5
-2
3
-4
1
-6
1 // j == 23 which is different from -6, so s is 1

Answer 2

j is an int?:-0
