Question

In the last class I spoke of C bitwise logical operators. They       are &, | , >>, << for AND, OR and right and left       shifts.
      You are to write two C methods to extract and insert bytes into an       int.
      
      The first is  called GetNthByte that will take two  arguments       Value and ByteNdx, where ByteNdx is 0,1,2, or 3.
      
      The prototype for GetNthByte is  
          unsigned char GetNthByte (int  Value, int ByteNdx);
      
      GetNthByte will return the byte specified by ByteNdx as we count       the bytes from low to high 0 , 1, 2, 3.
      Thus
          GetNthByte(0xFACECAFE, 2) will return 0XCE, and       NthByte(0xFACECAFE, 1) will return 0XCA.
    
    PutNthByte will return a newly created value created by putting       a new byte into the byte specified by ByteNdx, again as we count       the bytes from low to high 0 , 1, 2, 3.
    
    The prototype for PutNthByte is
        unsigned int  PutNthByte (int  Value, int ByteNdx, unsigned char     NewByte);
    
    As usual you will create a script of your source, the creation       of executable, and execution. You may hardcode calls to NthByte in       your main. Use the %x format descriptor for output.
       
      Some interesting possible cases to try for GetNth and       PutNth
      
          Value                             ByteNdx              NewByte
             -1                                 2                              0xA
            0xDEADBEEF                 3                          'A'
            2^32 - 1                        2                                 0
            127                              3                                  0xF
