Lisp for the C++ programmer: cond expression

Here is the example for the cond expression of Common Lisp and its C++ equivalent.

 ; int x = 10;  
 ; if (x < 10) {  
 ;    puts("x is smaller than 10");  
 ; } else if (x > 10){  
 ;    puts("x is bigger than 10");  
 ; } else if (x == 10){  
 ;    puts("x equals to 10"));  
 ; }  
   
 (setq x 10)  
   
 (cond  
     ((< x 10) (print "x is smaller than 10"))  
     ((> x 10) (print "x is bigger than 10"))  
     ((= x 10) (print "x equals to 10"))  
 )
