Question

Given the following JavaScript script segment: var x=0; var y=2; var z=0; if(x==0|| y==0) {x=1;} else if (x!=0 || y!=0) {x=y;}} else {if (y ! = 0 && z! = 0) {x=z;} else{x = false;}} What is the final value of x? a. 0 b. 1 c. 2 d. false What is the result of evaluating the following expression: 41 % 8 a. 0 b. 1 c. 2 d. all of the above e. none of the above What kind of errors can occur in a Javascript program: a. Logic errors b. Syntax errors c. Runtime errors d. all of the above e. none of the above

Explanation / Answer

Q: What is value of X ?

Here in first if condition will not get statify for a given variable values above. becasue x= 0 and y not equal to 0. So the interpreter goes to else if and check for the conditon with declared varaiable values given. and now finally reached to else condition here,

else {

         if (y!=0 && z !=0) ...............but here this conditon also fails because y = 2 and z = 0

         {

           x=z

          }

So finally, else after this will be executed and the values of x here is False

So, Answer is FALSE.

12 Q: Before answering this, I want you to know what is modulus.

Modulus means, it divides left-hand operand by right-hand operand and returns remainder.

41% 8.

Means 41 is divided by 8 and the reminder will be. 1

So Answer is : 1 (I mean: option A)
