    // The sizeof funtion outputs the size of any data type. 
  //If you want to know the size of datatype in long ints use %ld (this is the safe way to 
  //do it if you have a newer compiler. Therefore, this program prints the size of a char, 
 //short int, int, and long int. This is from smallest to biggest; although, 
  //an int and long int are of the same size.
