First time b is 0 so a is 0

Now after b++, b will be 1

b = ++c, here c is 0 but after ++c, c is 1 so b will be 1

and c = 3

So
a = 0
b = 1
c = 3

Note: ++c means pre increment, first increment by 1 then assign

b++ means post increment, first assign then increment by 1

Lekhraj Singh

Here what you have done

a = b++;
// b is unassigned so by default it will take 0 as you have used post increment so first the value 0 is assingned then the value of b goes to 1

// a = 0;

Then
b = ++c;
// here you used pre increment so first the unassigned value of c goes to 1 then assings the value 1 to b

// b = 1;

c = 3;
// now you assigned the value 3 to variable c

// c = 3;

So the output is 0:1:3
