Q1:

Are the following two statement same?
1. a <= 20 ? (b = 30): (c = 30);
2. (a <=20) ? b : (c = 30);

A Yes

B No

ANS:B - No

No, the expressions 1 and 2 are not same. 1. a <= 20 ? (b = 30) : (c = 30); This statement can be rewritten as, 


if(a <= 20)
{
    b = 30;
}
else
{
    c = 30;
}
2. (a <=20) ? b : (c = 30); This statement can be rewritten as, 

if(a <= 20)
{
    //Nothing here
}
else
{
    c = 30;
}
