ans=14 bcoz && operator says if both sides are true the value is true here in this example 14&&23 means true&&true bcoz compiler understand all digits true without 0(false) if u give value of variable a is 0 then the condition is false and else part is executed

If it's JavaScript, the output will be a because every number other than zero is true.

Maybe I'm wrong, but I think 1 is true and 0 is false. So if a and b both are one, then it will be true, and the if statement will execute. If not, the if statement will not execute.

@J.G. Any number other than zero is true. It's not just 1.

@Cheeze But before, you said in JavaScript. Is it just in js or in all languages?

@J.G. Since I only know JS, I never try it in any other languages. I believe it works the same as other languages but who knows I might be wrong.

Output is 14. The condition is true. "negative or positive. Anything that's not a 0 is a true value in if" source: http://stackoverflow.com/questions/14646718/if-statement-integer

@Jafca That makes sense, but I tried it, and if something other than 1 is put in, it doesn't work.

@Jafca I just realized I had a nested if statement that wasn't supposed to be. My logic in the program then gave me the wrong answer. That makes sense.

the outpur of this will be an error as you are asking an if without any parameters, you are just saying ( if a and b ) ?????? you need to supply some parameters for the program to check, etc if a and b larger than three (then) some code ( else ) some code.
