OR statement returning wrong number

Question

If i put 1 or 2 into this it will return 4. Why is this?I\'m more used to python stuff so sorry if this is rather basic.

e = 1;
f=0;

if(e==1){f=1;}
if(e==2){f=2         


        

Answer 1

Try replacing :

if(e== 3 or 4){f=4;}

with

if(e == 3 or e == 4){ f=4; }

The value 4 is considered to be TRUE by the language. In your code, 1 == 3 is FALSE, so the if statement is looking at (FALSE or TRUE) which is equals TRUE, so f is set to 4.
