-var.....type: declare variables with/without values. Support multi variables and type can be written as int/float/char/string/bool. <{1+1}> is a value but 1+1 not(it's expression)

-example:

import string,iostream var a,c,d = 1, <{(2*2+6)/2}> ,4 int var b = "hello world" string var f1,f2,f3 float var c1 char var b1 = <{1+1==2}> bool input(f1) print(a," ",c," ",d," ",b," ",b1," ",f1)
