the if statement in TCL

Question

I have a question about if statement in tcl of the following code:

if {(($number == 1)&&($name == \"hello\")) || (($number == 0)&&($name == \"yes         


        

Answer 1

In ($number == 1) number is assigned 1 and the comparison is made.Ex: 1==1 here output is Boolean. But in {$number == 1 && $name == "hello"} $number is not assigned because of flower bracket $number is compared with 1 so output obtained is not Boolean.
