Answer:
4) 3 11 44
Explanation:
Given data
int [] val = { 3, 10, 44 };
The total number of parameters of given array are 3, so total length of array is also 3.
The indexing of array starts with '0', Therefore the indexes of array with length zero are: {0,1,2}
The value of array at index 0 is = 3
similarly,
value at index 1 = 10
value at index 2 = 44
Here, Int i = 1 is storing the value '1' in integer variable i.
In addition to that, any value of index 'i' of an array is selected using array[i].
Therefore,
val[i] is selecting the value of array located at index '1' because i = 1.
val[i] = val[1] = 10
val[i]+1 is selecting the value of array located at index 'i' that is (1) and adding 1 to it
=> val[i] = 10
=> val[i]+1 = 10+1 = 11
Finally,
val[i] = val[i]+1; is copying the val[i]+1 = 11 to value placed at index 1 (10). Hence, the output would be {3 11 44}. So 4th option is correct.

The ____ operator executes one of two expressions based on the results of a conditional expression.
a. .
b. ( )
c. ,
d. ?:
Answer:
(d) ? :
Explanation:
The ternary operator (? :) is an operator that executes one out of two expressions based on the results of a conditional expression. It is a faster or shorthand way of writing an if ... else statement. The operator checks the conditional expression and depending on whether it is true or false, one of its two statements will be executed. For example:
String correct = (4 < 5) ? "yes" : "no" ;
In the code above,
i. the conditional statement is (4 < 5) and this will be tested for to return true or false.
ii. the first expression (the one after the ?) is "yes" which will be executed if the conditional statement returns true.
iii. and the second expression (the one after the : ) is "no" which will be executed if the conditional statement returns false.
Therefore, since the conditional expression returns true for 4 < 5, the first expression will be executed. i.e "yes". This means that the String variable <em>correct </em> will have a value of "yes".
