Question

what will be output of the following program
a.) 1,2,3
b.)1,3,2
c.)1,3,3
d.)3,2,1

Answer 1

A quiz question? The answer is 1, 2, 2, but such an option isn't there? Okay I don't really know

Answer 2

It's 1 2 2
a is 1
So you print "a", after that ++a add 1 to the a, then a is 2.
And after that a++ used, this code first use a and after that add 1 to the a.
In fact printf(++a) is:
a = a + 1 //a is 2 now
printf(a)

And print(a++) means:
printf(a) //a printed at first
a = a + 1

1, 2 , 2
