Answer / pavan_mustyala
Method1:
optimised code is to "left shift" the number 7 by 3 times.
Reason: 8 is (2 raised to power 3). So (7 * 8) is
equivalent to (((7*2)*2)*2). To multiply a number by 2,
shift it by 1 bit Left.
Method2:
Not optimised but it works. Addition in a loop.
int func()
{
int i;
int result = 0;
for(i = 0; i < 8; i++)
{
result = result + 7;
}
return result;
}

printf("%d",result);
}
