This code performs the following actions:
-
Initialization: A variable
myVar
is set to1
.int myVar = 1;
-
For Loop: A
for
loop runsi
from 1 to 100 (inclusive).for (int i = 1; i <= 100; i++) { ... }
-
Bitwise Left Shift: Within the loop, the line:
myVar = myVar << 1;
performs a bitwise left shift operation on
myVar
. This operation doubles the value ofmyVar
because shifting the bits to the left by 1 is equivalent to multiplying by 2. -
Comparison: Inside the loop, the code checks if the new value of
myVar
is not equal toi * 2
.if (myVar != i * 2) { return false; }
If the condition is true (
myVar
is not equal toi * 2
), the code immediately returnsfalse
. -
Return Statement: If the loop completes without triggering the
if
condition (i.e., it finds no mismatches), the code exits the loop and returnstrue
.return true;
What does the code do?
-
It checks if, for each iteration,
myVar
(doubled using bitwise left shift) is always equal toi * 2
. Since1 << 1
starts doubling from 2, and so on, the values ofmyVar
will indeed matchi * 2
. -
The code ultimately confirms that repeated left-shifting produces the same result as multiplying
i
by 2.
Result:
- The function will always return
true
, asmyVar << 1
(left shift) andi * 2
will align for every iteration of the loop.
