    chars to int

    Why does print() put the string in reverse order ??

    Code:
    void print (unsigned int num)
    {
     int i;
    
     typedef union
     {
      unsigned int number;
      char string[4];
     } DATA;
    
     DATA data;
    
     data.number = num;
    
     for (i = 0; i < 4; i++)
      printf ("%c", *(data.string + i));
     
     putc ('\n', stdout);
     
     return;
    }

    This is because the low byte of the integer is stored before the high byte of the integer.

    Example: 0x31323334 (1234) is stored in memory as: 0x34 0x33 0x32 0x31.
