   I think that is wrong.   
      
   C is a little strange as languages go, but you can have an expression   
   statement like:   
      
      1 + 1   
      
   which says to add one and one, and then ignore the result. It has a value, but   
   no meaning.   
   I suspect most compilers won't even do it, but I never looked.   
      
   More common is a function call with side effects, and ignore the value.   
      
   printf("Hi there!");   
      
   is an expression with the value ignored, but with a meaning.
