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.
