C = ++a + ++a + ++a; ans is 22 but how 6+7+8 = 21 how it became 22 !!

Alejandro Visiedo

• Mar 5th, 2016

It is the same as:
a = 5;
c = (a=a+1) + (a=a+1) + (a=a+1);
and the second block would be the same as:
c = a + (a=a+1) + (a=a+1); a=a+1;
So that, the result will be:
* a=8; c=21, in the first case.
* a=8; c=18, in the second case.

Why does ++i * ++i give 49 when i=5?

As per rule y=++x * x++ * ++x; if we tabke x=2;
y= 3 * 3 * 4;
y= 36
and x = 5

See we are available with i=5; so
++i * ++i = 49
as
++i executes first, result 6 and i= 6;
the second (++i) executed , and the result is 7 so the initialization done for int i is 7
therefore i*i =
7*7= 49
