Convert 2 bytes into an integer

Question

I receive a port number as 2 bytes (least significant byte first) and I want to convert it into an integer so that I can work with it. I\'ve made this:

char buf[         


        

Answer 1

I receive a port number as 2 bytes (least significant byte first)

You can then do this:

  int number = buf[0] | buf[1] << 8;
