if statement not working right?

Question

I\'ve looked and looked with the debugger and cannot seem to figure out why the IF statement always prints the message.

The IF statement checks to see if yesno != \'

Answer 1

you cannot OR an expression (yesno!='Y') and a statement ("N") which is also an expression. its only two or more expressions that can be combined using || and && to get the required output.

if(yesno!="Y"||"N")

is actually

if(yesno!="Y" || TRUE)

which is always true because:

Exp||TRUE=TRUE 

regardless of the expression.

use if(yesno!="Y"|| yesno!="N")      // and in this case its && and not || i think
