Homework Statement
folks,
I have a small problem understanding a function as to what its doing:
I have run this program in C++. I will comment the lines of code as per my understanding. Your insight would be useful
unsigned int myfunc(unsigned int n)
{
// for n here I took 1200
unsigned int temp =
//logical shift done here as it is unsigned, division for 1200 came to 0 as it was rounded
(n >> 24) |
// logical shift as well, logical and operation with hex value, result is 262144
((n << 8) & 0x00FF0000) |
// logical shift as well, logical and operation with hex value, came to 0 as it is rounded
((n >> 8) & 0x0000FF00) |
// computes to 2952790016
(n << 24);
//temp is then the sum of all operations which in this case is 0 + 262144 + 0 + 2952790016 totaling 2953052160.
return temp;
the value returned is the sum of all operations.
}
thanks for your help.
