Back 46

the first is false idk about the sec one true

Front 47

which operator will execute first

Back 47

idk

Front 48

what will print out

int a =1

if (1==a){

int a=2;

}

Back 48

2 within the {} 1 outside the {}

Front 49

int a=1;

switch (a){

case 0:

a =1

break;

case....

Back 49

Another one is missing a break after case 1 and the answer to that one is 3!

Front 50

one has all the proper breaks!

Back 51

that one is 2
