Why Hi is printed only once and Not Three times??

Answer 1

Because 5,3,0 makes no sense and therefore compiler gives an error . The only reason it ran was due to do statement.

Following code will print 3 times,

int i=3;
do{
printf("Hi");
}while(--i);
return 0;
}

Answer 2

Here's info about comma operator. May it helps you understand why the code is acting as it does.
